For those of ordinary skill, on the premise of not paying creative work, can be implemented with obtaining others according to these accompanying drawings
Example.
Embodiment of the present utility model 1 as shown in Figure 1, Figure 2, Figure 3 shows, the utility model is a kind of difficult screw dismounting device,
Its stripping attachment body 1 has trigger 21, handle 11, gun-shaped shape.
Be installed with body 3 on stripping attachment body 1, in body 3 impact pole 31 be equipped with, be arranged with impact pole 31 with
The sealing ring 32 that the inwall of body 1 coordinates.Impact pole 31 can be to move in body 3.
In the right of impact pole 31 in body 3, namely the rear end of body 3, a bullet 4 is filled in, bullet 4 has the He of bullet 41
Gunpowder 42.Stripping attachment body 1 is provided with a pressing pole 7 for being connected with spring 71, and pressing pole 7 can expose body 3 after pulling open
Rear end, for loading and taking out bullet 4, pressing pole 7 unclamps can be pressed in the rear end of body 3 and push down bullet 4.
The rear of stripping attachment body 1 is provided with firing lock corresponding with the position of gunpowder 42, and firing lock hits including one
What one percussion spring 22 at the rear portion for being located at stripping attachment body 1 that pin 23, striker 23 are connected, percussion spring 22 were connected pulls
Machine 21.Firing lock is existing structure, can compress percussion spring 22, and after cocking 21, percussion spring 22 unclamps, striker
23 are released by percussion spring 22, fire gunpowder 42.
The front end spiral shell of body 3 is provided with a sleeve 5, and sleeve 5 has the through hole 50 for being available for impact pole 31 to pass through, outside sleeve 5
Wall is provided with deep-slotted chip breaker 51.
One end face of one screw impact head 6 is provided with blind hole 61, and the blind hole 61 is slidably set in before sleeve 5
End, the slide block (not shown) set by the inwall of screw impact head 6 is slidably embedded in deep-slotted chip breaker 51.Screw impact head 6
Another end face also is provided with that the blind hole 62 outside the screw head for needing dismounting can be set in.
When actually used：
The size of the screw terminal of the screw dismantled as needed, selects the He of screw impact head 6 of the blind hole 62 of correspondence size
The corresponding sleeve 5 of screw impact head 6, screw impact head 6 is mounted on sleeve 5, and sleeve 5 is mounted on body 3, loads bullet 4, with pressure
Elastic rod 7 is pushed down, and compresses percussion spring 22.
Blind hole 62 is enclosed within the screw terminal of the screw for needing dismounting, by trigger 21, striker 23 is released, fires gunpowder 42,
Bullet 41 is projected, and promotes impact pole 31 to project, and impact pole 31 hits the bottom of the blind hole 61 in screw impact head 6 through after sleeve 5,
Bolt impact head 6 is knocking-on, because the slide block set by the inwall of screw impact head 6 is slidably embedded in deep-slotted chip breaker 51, so
Screw impact head 6 is rotatably knocking-on.
Due to the energy instantaneous burst of gunpowder 42, so screw impact head 6 is bumped against with the speed that is exceedingly fast with huge energy needing
