Auxiliary grip rotary hand tool assembly method

The invention relates to a method for assembling an auxiliary grip rotary hand tool, in particular to a hand tool assembly technology which can realize a quick and simple assembly process.

Press, conventional hand tools refer to tools such as socket wrenches, T-wrenches, and Y-wrenches that require hand-held operation. These hand tools are mainly used to unscrew or tighten the screw parts (such as bolts or nuts), and the specific operation method is to hold the middle part of the handle of the hand tool with one hand to ensure the smoothness of the hand tool, and then Turn the handle of the hand tool with the other hand to achieve the purpose of unscrewing or tightening the screw. In addition, in order to increase the speed of rotation of the screw, the general user usually slightly bends the hand held in the middle of the handle, and then quickly rotates the handle with the other hand, and then uses the inertial rotation force to increase the rotation of the screw. Speed; however, in this way of operation, the hand tool is not able to maintain the smoothness of the shaft, and it will affect the rotation speed of the handle due to the resistance generated by the palm rubbing the middle of the handle, and even the friction grip. The handle is too long and the palm of the hand is broken, which causes inconvenience and trouble in the operation of the hand tool.

In order to improve the aforementioned shortcomings, the related art has developed a patent such as the new model of the Republic of China No. M315141, "Improvement of the grip of the tool, which has improved the grip and the adjustable grip position. Function, however, because the elastic body is uncompressed, the sliding sleeve is pressed against the elastic body and tightly abuts against the side edge of the limiting member, so when the holding position is adjusted, only Push the side of the thumb to rub the sleeve Move, then, in the adjustment process of the holding position, the thumb can be pulled and the operation is inconvenient due to the ergonomics, and the interference caused by the accidental sliding sleeve and the invalid operation are more likely to occur. Not only that, but also due to insufficient friction, the side edge of the thumb slips off the sliding sleeve, which causes the redness or broken skin of the thumb side to occur, resulting in operational inconvenience and great troubles. produce.

In addition, there is a patent as shown in the invention No. I410307, "The kit and the tool bar including the kit, and the assembly method thereof," which has the functions of holding the fast rotation and adjusting the grip position. Among them, the patent also discloses a method of tool assembly, however, due to the poor design of the structure and the configuration of the components, the following defects are caused:

1. When assembling the tool, press the two clips (ie, steel balls) on the two perforations on the first kit simultaneously with one hand, and then insert the elastic members from the top of the first kit with the other hand until the elasticity The smaller spiral pitch portion of the top end of the piece seals the two card members. Since the elastic member is required to release the hand of the card holder before the two card members are about to be touched, it is easier to let go. If the card is not detached, the assembly process must be repeated, resulting in inconvenience in assembly operation and an increase in assembly man-hours.

2. In the adjustment operation of the grip position, since the elastic member of the patent is uncompressed, the second sleeve is pressed against the elastic member and tightly abuts against the side edge of the stopper, so When making the first set of position adjustment, the second set can only be pushed down by the friction of the side edge of the thumb. Therefore, during the adjustment operation of the holding position, the thumb can be pulled off due to the ergonomics. It is easy to operate with inconvenience, and it is easy to cause interference and invalid operation caused by accidental contact with the second kit. Not only that, but also due to insufficient friction, the side edge of the thumb slips off from the second set. , causing redness or broken skin on the lateral side of the thumb The injury occurred, which caused inconvenience and troubles in the operation of the quick-turn position adjustment.

In view of this, the above-mentioned patents are not perfect in terms of structural design, configuration between components, adjustment of holding position, and assembly process. Therefore, there is still a need for further improvement, and based on related industries. Under the urgent need, the inventors have continuously developed a set of inventions different from the above-mentioned prior art and patents through continuous efforts.

The main purpose of the present invention is to provide an auxiliary grip rotary hand tool assembly method, which is mainly to make the assembly process of the hand tool and the adjustment operation of the holding position easier and simple by changing the component arrangement and the assembly process. In order to achieve the purpose of shortening the assembly man-hour cost, and in the adjustment operation of the holding position, the thumb can be easily pulled down and the force is applied to adjust the holding position, thereby being ergonomically operative. The operation is simple and smooth, and the adjustment operation time of the holding position is shortened. The technical means adopted for achieving the main object of the present invention is to thread the magnetic component inside the front portion of the joint member so that the magnetic component is located near the perforation of the joint member. The clip is embedded in the perforation so that the clip is held by the magnetic component without being detached from the perforation. The elastic member and the control member are sequentially sleeved on the outer circumference of the front portion of the coupling member, so that the elastic member elastically acts between the control member and the coupling member. Place the kit in the front of the coupling so that the front of the control protrudes from the front of the kit. The fastener is sleeved on the front end of the sleeve that protrudes out of the sleeve. The rear end of the shaft of the body is sequentially passed through the fastener, the kit, the control member and the coupling member. The magnetic component is then withdrawn from the coupling member, and the clamping member abuts against the peripheral surface of the shaft of the body.
