Specific embodiment:
As shown in Figure 1-Figure 3, present embodiment uses following technical scheme: it includes gear-box 1, motor 2, motor
Main shaft 3,4, first jiaos of teeth 5 of clutch, the first helical gear 6,7, second jiaos of teeth 8 of the second helical gear, the third angle tooth 9, cylinder 10,
Connecting rod 11, collet 12, handle 13, switch 14 are provided with motor 2 in gear-box 1, electric machine main shaft 3, motor are provided on motor 2
It is provided with umbrella shape curved tooth on main shaft 3, clutch 4 is provided on gear-box 1, first jiao of tooth 5, are provided on clutch 4
One helical gear 6 and the second helical gear 7, wherein first jiao of tooth 5 is combined with 6 elasticity of the first helical gear, the first helical gear 6 and second is oblique
Gear 7 is meshed, and the second helical gear 7 is set on second jiao of 8 axis of tooth, and second jiao of tooth 8 is nibbled with 9 phase of the third angle tooth on cylinder 10
It closing, cylinder 10 is arranged in gear-box 1, and one end of cylinder 10 is connect with connecting rod 11, and the front end of gear-box 1 is equipped with collet 12,
The lower section of gear-box 1 is equipped with handle 13, and switch 14 is equipped on the medial surface of handle 13.
Wherein, the outside of the gear-box 1 is provided with water conservancy diversion reinforcing rib, can play reinforcement cabinet, heat dissipation and wind-guiding
Effect；There are two attachment 15 and springs 16 for the junction installation of the handle 13 and gear-box 1, utilize attachment 15 and spring
16 are flexibly connected with gear-box 1, play cushioning effect；There are two overflow hole 10-1, cylinders 10 for setting on the cylinder 10
It is inside provided with and hits sub- 10-2 and piston 10-3.
As shown in figure 4, if only one overflow hole 10-1, and when aperture is bigger than normal, then hit sub- 10-2 and piston 10-3 it
Between the pressure in space will be small, hit that sub- 10-2 is small with the mobile distance of piston 10-3, and impact force is small, and machine burden is light；Anti- mistake
Come the aperture overflow hole 10-1 it is less than normal when, spillage drag is big, and the pressure for hitting the space between sub- 10-2 and piston 10-3 will increase, and hits
Sub- 10-2 is easy that piston 10-3 is followed to walk, and hits that sub- 10-2 stroke is big, and impact force is also big, and machine burden is big, especially in figure A condition
When, sub- 10-2 and striker 10-4 rigid contact are hit, if overflow is inadequate, and its is easily damaged machine.Present embodiment
In order to solve this problem, two overflow hole 10-1 are designed, working condition one of overflow hole when scheming B and C, which is already expired, hits son
10-2 sealing ring, becomes exhaust outlet, only remains next overflow hole, and air overflow at this time is few, increases the stroke for hitting son, and raising is hit
Power is hit, and when working condition is when scheming A, hitting sub- 10-2 sealing ring has returned outside two overflow holes, is hitting sub- 10-2 and striker
Before 10-4 rigid contact, can abundant overflow, mitigate machine burden improve working efficiency.
The working principle of this specific embodiment:: electric machine main shaft 3 drives first jiao in clutch 4 by angular motion
