Transmission parts 400 are inputted to be sequentially connected by one-way clutch mechanism and eccentric part 210.It is defeated that one-way clutch mechanism is set to power
Enter between the output end of transmission parts 400 and eccentric part 210.Specifically, one-way clutch mechanism is set to the defeated of reduction assemblies
Between outlet and eccentric shaft 211.During the storage of impact energy, one-way clutch mechanism is in contact condition, i.e. deceleration group
Driving condition is between the output end and eccentric shaft 211 of part.Eccentric shaft 211 rotate and by lifting frame, impact bar 231 and
Boss 232 drives compressed spring accumulation of energy.During the release of impact energy, one-way clutch mechanism is in discrete state, that is, subtracts
Discrete state is between the output end and eccentric shaft 211 of fast component, spring energy-storage mechanism 100 drives impact bar 231 and boss
232 move in a straight line, and impact bar 231 only drives eccentric shaft 211 and bearing 212 to make rotating motion by lifting frame, deceleration group
Part is not rotated synchronously with eccentric shaft 211.During the release of impact energy, since abrupt release goes out stored energy, meeting
Very big impact force is generated, one-way clutch mechanism is in discrete state at this time, effectively protects reduction assemblies and is not hit power
Influence.And by the energy discharged it is more as far as possible be used to impact to by impulse member, improve punching provided by the present invention
Hit the target efficiency of device.

Transmission connection is realized in contact.Specifically, bevel gear slowing-down structure include as driving wheel power input shaft cone pinion 410 with
And the large bevel gear 420 as driven wheel.Shifting block 421 is set to an end face of the large bevel gear 420 far from the gear teeth, drive pin 2113
It is set to an end face of eccentric shaft 211.Using shifting block 421 and drive pin 2113 realize large bevel gear 420 and eccentric shaft 211 it
Between transmission and separation, have that structure is simple, the operation is stable, is easy to contact with isolated advantage.In large bevel gear 420 and partially
In the separation process of mandrel 211, also without disturbance or impact.Further, the quantity of shifting block 421 and drive pin 2113 is one
It is a.It can guarantee that eccentric shaft 211 turns over 180 ° still and will not connect with large bevel gear 420 during one-way clutch mechanism separation
Touching is conducive to compressed spring all stored impact energys of release.As shown in figure 9, as a kind of achievable mode, it is eccentric
Axis 211 has shaft 2111, and large bevel gear 420 is rotatably dispose in the shaft 2111 of eccentric shaft 211 by rolling bearing.
As shown in Fig. 8 and Figure 10, during the storage of impact energy, the shifting block 421 and bias of 420 end face of large bevel gear
The contact of drive pin 2113 of 211 end face of axis reaches upper dead center position to drive eccentric shaft 211 to rotate up to eccentric shaft 211.When inclined
Mandrel 211 crosses upper dead center position, and impact energy starts to discharge, and under the driving of energy-storaging spring, lifting frame drives eccentric shaft 211
Quick rotation, the revolving speed of eccentric shaft 211 are more than the revolving speed of large bevel gear 420, and drive pin 2113 is separated with shifting block 421, while big
Bevel gear 420 is continued to rotate along former rotation direction.In eccentric shaft 211 from upper dead center position to during rotating 180 °, compress
Spring, which releases energy, to be finished, and the rotation of eccentric shaft 211 runs out of steam.The shifting block 421 of 420 end face of large bevel gear is continuing to rotate
It is contacted again with the drive pin 2113 of 211 end face of eccentric shaft in the process, into the process of storage impact energy next time.
