Positioning piece, through being stamped to form, it has a socket part with metal sheet, is socketed on the joint portion of this accommodating body; Two location divisions are the two opposite side ends that are connected in this socket part, and respectively this location division has a protuberance, and this two protuberance is to be resisted against respectively in the locating slot at opposite position place on this adjustment knob.
The beneficial effects of the utility model are:
Electric tool of the present utility model, its assembling is comparatively easy, and turning knob is comparatively smooth and easy.
Description of drawings
For further specifying concrete technology contents of the present utility model, after being described in more detail in below in conjunction with embodiment and accompanying drawing, wherein:
Fig. 1 is the three-dimensional exploded view of the utility model one preferred embodiment.
Fig. 2 is the part member front view in embodiment illustrated in fig. 1.
Fig. 3 is the part member assembling view in embodiment illustrated in fig. 1.
The specific embodiment
Seeing also Fig. 1 to shown in Figure 3, is the electric tool 100 that the utility model provides a preferred embodiment, and it includes:
One casing 10 is by 11 of two housings and connect and form.
One electro-motor 20 is to be located in this casing 10, and its output shaft is provided with a gear 21.
One battery 30 is removably to be incorporated on this casing 10.
One switch 40 is to be fixedly arranged on this casing 10, and electrically connects with this battery 30 and this electro-motor 20 respectively, but with conducting or block this battery 30 and the electric connection of 20 of this electro-motors.
One speed change and outputting torsion control device 50 are to be located in this casing 10, and it includes an accommodating body 51, one group of planetary gearsets (not shown) and rotating disk 52; Wherein, this accommodating body 51 has one and is the cylindric joint portion 512 that holding part 511 cylindraceous and axially is connected in these holding part 511 1 ends, along having an external screw thread 513 on the outside wall surface of this joint portion 512; This planetary gearsets is to be arranged in this joint portion 512, and is connected with the gear 21 of this electro-motor 20; In addition, this planetary gearsets has an output shaft 53 and stretches out this joint portion 512; These round turntable 52 central parts have a perforation 521, has an internal thread (not shown) on the hole wall of this perforation 521 with on the external screw thread that is incorporated into this joint portion 512, by rotating this rotating disk 52 this rotating disk 52 is moved on this joint portion 512, and adjust the maximum outputting torsion of this electric tool 100 thus; In addition, this rotating disk 52 has most engagement grooves of arranging along its periphery 522.
One adjusts knob 60, be one to be lid cylindraceous and to have a body cylindraceous portion 61 and a roof 62, and these roof 62 central authorities has a circular open 621 (as shown in Figure 2); What have majority on these body portion 61 internal faces helps 611 in conjunction with protruding, and has the convex cone 622 that majority is the radiation-like arrangement on the internal face of this roof 62, and 622 of each two these convex cones form a locating slot 623; This adjustment knob 60 is to be incorporated on this casing 10 in rotary mode, and it helps 611 to be to be embedded in respectively in the engagement groove 522 of this rotating disk 52 in conjunction with protruding, can drive this rotating disk 52 and rotates on the joint portion 512 of this accommodating body 51 to rotate this adjustment knob 60;
