Description

  The present invention relates to a lighting tool for a driver tool that is detachably attached to a driver tool so that a screw can be easily attached or removed in a dark place.

  Conventionally, when attaching or detaching a screw in a dark place indoors or outdoors, a flashlight to be hand-held is prepared together with a driver tool, or a headlamp is attached to the head. In the case of a flashlight, hold the flashlight in one hand and hold the driver tool in the other hand, illuminate the light of the flashlight on the head of the screw, The screw is attached to and detached from the blade tip. In the case of the headlamp, since both hands are free, the shaft portion of the driver tool is supported by one hand, and the handle portion is grasped by the other hand, and the screw is removed.

  In the former case, the driver tool must be operated with only one hand, so the hand is likely to become unstable and difficult to work. In the latter case, it is easy to operate the driver tool because both hands are free, but with the headlamp alone, the illumination is blocked by the hand and the screw becomes a shadow, making it difficult to see the screw and the tip of the driver tool. There are challenges.

  In view of the above problems, for example, an electric part such as a battery and a switch is incorporated into a handle part of a driver tool together with a light emitting body that illuminates the blade tip portion of the shaft portion, and the light emitting body is caused to emit light by pressing the switch during operation to illuminate the blade edge portion. Driver tools have been developed (see, for example, Patent Document 1).

Utility Model Registration No. 3119888 (page 3-4, FIG. 2)

  However, the driver tool according to Patent Document 1 is convenient in work because it is not necessary to prepare a flashlight separately, and the light of the light emitter is blocked at hand like a headlamp. Although there is nothing, it is easy to see the screw, but it is necessary to incorporate electric parts such as a light emitter, a battery, and a switch into the handle portion of the driver tool. For this reason, the structure of the driver tool becomes complicated, and it has a fatal problem that the production of the driver tool becomes troublesome and the production cost becomes high. In addition, since the light emitter is provided integrally with the driver tool, driver tools of various sizes including the light emitter must be manufactured. Furthermore, if some of the electrical components incorporated in the handle are damaged, the driver tool itself needs to be replaced with a new one, which is not economical.

  Therefore, the present invention has been made to solve the above-mentioned problems, eliminates the need to process the driver tool so as to be detachably attached to the driver tool, eliminates the need for high production costs, and allows for various sizes of driver tools. It is an object to provide a lighting tool for a driver tool that is applicable and convenient and easy to handle.

  In order to achieve such an object, a lighting tool for a driver tool according to the present invention includes an illuminating unit provided with a light emitter, and an attaching part that is detachably attached to a shaft part of the driver tool. A tightening screw which is formed in a cylindrical shape having both ends opened so that the shaft portion is loosely inserted, and a screw hole is formed in the outer peripheral surface of the mounting portion, and a tip of the screw hole is freely advanced and retracted into the mounting portion. When the attachment portion is mounted on the shaft portion of the driver tool, the light emitter is directed toward the blade edge portion at the tip of the shaft portion to illuminate the blade edge portion.

  A lighting tool for a driver tool according to the present invention includes an illumination part having a light emitter and an attachment part that is detachably attached to a shaft part of the driver tool, and the attachment part is a cylindrical shape in which the shaft part is loosely inserted. A screw hole is formed on the outer peripheral surface of the mounting portion, and a fastening screw whose tip freely moves forward and backward in the mounting portion is screwed into the screw hole, and the mounting portion is mounted on the shaft portion of the driver tool. In this case, the light emitter is directed toward the blade edge part at the tip of the shaft part so as to illuminate the blade edge part. In this way, it is not necessary to incorporate electric parts such as a light emitter and a battery in the driver tool itself, and only a driver tool illuminator needs to be manufactured, so there is no high production cost. Moreover, since it can be applied to driver tools of various sizes by being detachably attached to the driver tool, it is versatile and convenient. Further, even when the driver tool lighting device is damaged, it is sufficient to repair or replace only the driver tool lighting device, so that the driver tool can be used as it is and is economical.

XX line expanded sectional view of FIG. The side view of the integrating watt-hour meter of the state which uses the driver tool to which this invention is applied.

  BEST MODE FOR CARRYING OUT THE INVENTION The best mode of a driver tool lighting device according to the present invention will be described below in detail with reference to the drawings. 1 is a perspective view of a lighting tool for a driver tool according to the present invention, FIG. 2 is a perspective view of the lighting tool for a driver tool mounted on the driver tool, and FIG. 3 is an enlarged sectional view taken along line XX of FIG. is there. The driver tool illuminator A includes an illuminating unit 3 that holds an illuminator 2 that includes an LED 1 that is a light emitter, and an attachment unit 4 into which a shaft part b1 of a driver tool B described later is loosely inserted. Moreover, the illumination part 3 has the holding | maintenance part 5 in which the lighting fixture 2 fits.

  The holding part 5 and the attaching part 4 are both formed of a synthetic resin material, and the holding part 5 and the attaching part 4 are made of cylinders having substantially the same outer diameter and the same length. In both cases, the central axes are parallel and integrally formed. The holding part 5 has an opening 5a at one end and a closing 5b at the other end, and a columnar lighting device 2 is tightly fitted into the holding part 5 from the opening 5a side. The lighting device 2 incorporates electrical components such as an LED 1, a battery (not shown), and a switch 6 in a compact manner. Specifically, the LED 1 is provided at the tip of the lighting fixture 2 protruding from the opening 5 a of the holding portion 5, and the switch 6 is provided on the outer peripheral surface of the lighting fixture 2 outside the opening 5 a. The LED 1 is located on the central axis of the cylindrical holding portion 5 and illuminates the front thereof.

  Both ends of the mounting portion 4 have openings 4a and 4b, and the inner diameter dimension is set so that the shaft portion b1 of the driver tool B of various sizes can be loosely inserted. A screw hole 7 is formed in the outer peripheral surface of the mounting portion 4, and a fastening screw 8 made of synthetic resin is screwed into the screw hole 7. The tightening screw 8 is knurled on the outer peripheral surface of the head 8a. The screw 8b of the tightening screw 8 is attached to the mounting portion by picking up the head 8a with a fingertip and rotating it forward or backward. 4 can move forward and backward freely. Therefore, by pushing the tip 8c against the outer peripheral surface of the shaft part b1 of the driver tool B, the driver tool illumination tool A can be fixed. The screw portion 8b moves back and forth in a state of being orthogonal to the central axis of the cylindrical mounting portion 4.

  Although the illumination tool 2 is fitted in the illumination unit 3, the illumination unit 3 itself may be formed as an illumination tool. That is, electric parts such as LEDs, batteries, and switches may be directly incorporated into the illumination unit 3. As described above, the mounting portion 4 and the holding portion 5 are formed to have substantially the same outer diameter, and the central axes are formed in parallel and in close contact with each other, so that it can be formed compactly as a whole. The driver tool illumination tool A can be downsized.

  The driver tool illuminator A according to the present invention has the above-described configuration. Next, a method of mounting the driver tool illuminator A on the driver tool B will be described. The driver tool B has a metal shaft portion b1, and a plus-shaped or minus-shaped blade edge portion b2 is formed at the tip thereof (in this case, a minus-shaped blade edge portion b2). Further, a handle portion b3 that is a combination of synthetic resin and rubber is provided at the base end of the shaft portion b1, and the base end side of the shaft portion b1 enters the handle portion b3. Further, the handle b3 has an outer peripheral surface that is formed into a curved surface along the direction of the central axis so that the handle b3 can be easily held by the hand, and is easily gripped. The driver tool B may have a wooden handle b3.

  Therefore, on the side of the blade edge portion b2 of the driver tool B, the central axis of the shaft portion b1 and the central axis of the mounting portion 4 are substantially coincident and the LED 1 faces the same direction as the blade edge portion b2, so Place A. Then, in this state, the cutting edge b2 at the tip of the shaft portion b1 is loosely inserted from the opening 4b on the side opposite to the LED 1 in the mounting portion 4, and the driver tool illumination tool A is positioned on the back end side of the shaft portion b1. In this state, the head 8a of the fastening screw 8 provided on the attachment portion 4 is rotated in a predetermined direction by the fingertip, and the tip 8c of the fastening screw 8 is brought into contact with the outer peripheral surface of the shaft portion b1. In this case, the shaft portion b1 is covered with a resin cylindrical cover b4 for safety, and the tip 8c of the screw portion 8b of the tightening screw 8 is brought into contact with the surface of the cylindrical cover b4. As a result, the driver tool illumination tool A is detachably attached to the driver tool B.

  Next, the screw attaching / detaching operation will be described using the driver tool B to which the driver tool illumination tool A is mounted in this manner. FIG. 4 is a side view of the integrated watt-hour meter in a state where the driver tool to which the present invention is applied is used. The integrated watt-hour meter C is generally mounted on the outer wall W of each house, and although not shown, a lead-in wire from a utility pole is connected and a wiring from the integrated watt-hour meter C is connected to a breaker in the house. In particular, in a dense residential area, the integrated watt-hour meter C is often mounted on a dark wall W narrowed between houses. For maintenance and inspection of the integrated watt-hour meter C in such a place, The driver tool B equipped with the driver tool illumination tool A according to the present invention is used for the attaching / detaching operation of the tightening screw.

  The integrated watt-hour meter C is attached to the front surface of the meter body c1 by a transparent cover member c2, and the lower end of the meter body c1 is a box-shaped terminal for connecting a distribution line (not shown). Part c3. The front surface of the terminal portion c3 is opened, and a terminal lid c4 that covers the terminal portion c3 is detachably attached to the front surface. More specifically, a sealing screw c5 is screwed into the left and right two portions of the terminal part c3 so that the attached terminal lid c4 does not come off, and the terminal screw c5 is attached to and detached from the terminal c3. The lid c4 can be opened and closed.

  Therefore, when the surroundings of the integrated watt-hour meter C are dark and the sealing screw c5 cannot be seen, the switch 6 of the illumination unit 3 is pressed to cause the LED 1 to emit light. Thereby, the light illuminates the blade edge part b2 side at the tip of the shaft part b1. Therefore, when the blade edge portion b2 of the driver tool B is brought close to the terminal lid c4 of the integrating watt-hour meter C, the position of the sealing screw c5 can be easily understood by the light of the LED. Next, as shown in FIG. 4, the blade tip b2 at the tip of the shaft portion b1 is placed in the groove c7 of the screw head c6 in the sealing screw c5, and the driver tool B is rotated in the direction indicated by the arrow in FIG. Thereby, one sealing screw c5 can be removed. Similarly, the other sealing screw c5 is also removed. After the terminal cover c4 is removed and the terminal part c3 is inspected, the terminal cover c4 is put on again and both the sealing screws c5 are attached to the original positions. Also in this case, if the LED 1 is illuminated as described above, the work can be easily performed without the sealing screw c5 being difficult to see.

  At this time, the driver tool illumination device A is compact because the attachment portion 4 and the holding portion 5 both have a cylindrical shape having a parallel central axis. Therefore, even if the sealing screw c5 is positioned close to the cover member c2 side on the upper surface of the terminal lid c4, the driver that rotates around the driver tool B when the sealing screw c5 is attached / detached. The tool illuminator A hardly hits the outer peripheral surface of the cover member c2 so that the rotating operation of the driver tool B is hardly hindered.

  As described above, the lighting tool A for the driver tool according to the present invention does not need to incorporate the electrical components such as the LED 1 and the battery into the driver tool B itself, and only the driver tool lighting tool A needs to be manufactured. It does not take. Further, since it can be applied to the driver tool B of various sizes by being detachably attached to the driver tool B, it is versatile and convenient. Furthermore, even when the driver tool illuminator A is broken, only the driver tool illuminator A needs to be repaired or replaced, and the driver tool B can be used as it is.
