Specific embodiment
With specific embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings: as Fig. 1 to Fig. 7 institute
Show, electric impact wrench, including rotary shaft 5 and the clamshell 1 being set in rotary shaft 5, described rotary shaft 5 is provided with spacing hole
51, several spacing balls 4 are installed in described spacing hole 51, described clamshell 1 is provided with chute 11, activity in described chute 11
Described spacing ball 4 is installed, described chute 11 end is provided with only stops mouth 111, and on described clamshell 1, buckle is provided with baffle plate 3, institute
State and torsion spring 2 is installed in clamshell 1.
Draw-in groove 12 is provided with described clamshell 1, is provided with hole clipping 121 in described draw-in groove 12, described baffle plate 3 is provided with card
Enter the card article 31 of described draw-in groove 12, described card article 31 is provided with projection 311.
It is provided with pin hole 53 in described rotary shaft 5.
It is tetragonal union joint 52 that the end of described rotary shaft 5 is provided with section, is provided with and cuts in described union joint 52
Face is the endoporus 521 of orthohexagonal, and described endoporus 521 is connected with described spacing hole 51.
Described torsion spring 2 is provided with first hook portion 21 and second hook portion 22, and described first hook portion 21 is inserted in described pin hole 53, institute
State baffle plate 3 edge setting jagged, described second hook portion 22 is arranged in this breach, and described first hook portion 21 and described second hook portion 22 are joined
Close thus fixing the position of described torsion spring 2.
The port that described spacing hole 51 is located within described rotary shaft 5 is provided with and only stops ring portion 511, described only stops ring portion
511 inner ring bore is less than the external diameter of described spacing ball 4 thus preventing described spacing ball 4 from passing through.
On described clamshell 1, described chute 11 number of setting is twice, the described spacing hole 51 of setting in described rotary shaft 5
Number be two.
It is provided with two spacing balls 4 in each described spacing hole 51.
After clamshell 1 is coordinated with spacing ball 4, in clamshell 1, it is provided with chute 11, spacing ball 4 has part in rotary shaft 5 simultaneously
In spacing hole 51, separately some in the chute 11 of clamshell 1, so, clamshell 1 cannot be carried out radial motion, and spacing ball 4
Limit motion and cannot drop out disengaging spacing hole 51.
Projection 311 on baffle plate 3 is fitted close with the hole clipping 121 of clamshell 1, so that baffle plate 3 cannot depart from clamshell 1.
Baffle plate 3 is therefore restricted from free motion, and clamshell 1 forms an assembly with baffle plate 3, so this assembly is in rotary shaft 5
On cannot be carried out move axially, that is, complete random sample, will not drop from rotary shaft 5.When pulling down baffle plate 3, need using one
Article, so that the card article 31 on baffle plate 3 bends in the hole clipping 121 on insertion clamshell 1, so that projection 311 departs from hole clipping
121, now just can split out baffle plate 3.
Accompanying drawing 3 show the retaining mechanism naturalness of this device: clamshell 1 under the twisting force of torsion spring 2, clamshell 1, turn round
Spring 2, baffle plate 3 rotates to position as shown in Figure 3 together.Spacing ball 4 is in by clamshell 1 outer ring impaction state, spacing ball 4 by
Interior compression, spacing ball 4 peak exceeds rotary shaft endoporus plane, can lock correlated parts, such as screwdriver bit.
Accompanying drawing 4 show the retaining mechanism open mode of this device, now can dismount screwdriver bit: clamshell 1 is rotated by external force,
Clamshell 1, torsion spring 2, baffle plate 3 rotates to position as shown in Figure 4 together.There is space, limit at clamshell 1 inside and spacing ball 4 cooperation
Position ball 4 can be freely-movable in clamshell 1.Now rotary shaft 5 endoporus can dismount screwdriver bit.Have due to inside spacing ball 4 clamshell 1
Space, spacing ball 4 can smoothly be installed in place or be removed to two side shiftings, screwdriver bit.Go when being applied to external force on clamshell 1
Remove, clamshell 1, under the twisting force of torsion spring 2, returns to naturalness, as shown in Figure 3.
Protection domain of the present utility model includes but is not limited to embodiment of above, and protection domain of the present utility model is to weigh
Sharp claim is defined, and any replacement that those skilled in the art that this technology is made is readily apparent that, deformation, improvement each fall within
Protection domain of the present utility model.
This utility model is simple and reliable for structure, easily manufactured low cost, can quick-clamping screwdriver bit, save labor time,
Improve work efficiency.
