Rigid shock, and reduce the beat that end effector 3 is closed and is generated in opening procedure, be conducive to obtain better Cheng Ding
Form.
3 closing course of end effector is as follows：Closure axis 34 is driven by taper transmission gear when being closed transmission component
When rotating along the first direction of rotation (first direction of rotation can be clockwise), which is being closed axis 34
On move down, at this point, being closed nut 35 drives direction movement of the nail bin groupware stent 32 towards nail-anvil assembly 31 until the end
Actuator 3 is closed.Since nail bin groupware stent 32 is cantilever design, in order to ensure the match result of end effector 3, generally
The front end 323 of nail bin groupware stent 32 is arranged to less than connecting portion 322, the purpose of the design is：If front end 323
Be arranged to it is concordant with connecting portion 322, then end effector 3 be closed during, front end (the nail bin group of nail bin groupware 100
It is located at the part of 32 front end 323 of nail bin groupware stent in part 100) elder generation is contacted with the tissue for being sewn and cutting, at this point,
The end effector 3 is also to be closed completely, if starting firing action at this time, match result is bad.Therefore, the nail bin groupware
Stent 32 has to move towards the direction of nail-anvil assembly 31 again, to realize being closed completely for jaw.During this, nail bin group
The front end 323 of part stent 32 will be applied to by the front end of nail bin groupware 100 be sewn and cut it is structural opposite
Power and micro- lift upwards, and then cause the whole slight oscillatory upward along the first direction of the nail bin groupware stent 32, due to nail bin groupware
100 be movably arranged on be closed nut 35 on, nail bin groupware stent 32 can relatively closed nut 35 swing along the first direction, therefore, even
Socket part 322 is stress weak part by the way that front end 323 to be arranged to the structure type less than connecting portion 322, thin to stress
Weak position is strengthened, and can avoid 32 bending of nail bin groupware stent, reduces the fatigue damage of nail bin groupware 100, improves nail bin
The service life of component 100.
Axis 34 is closed for the ease of fixation is described, 34 one end of the closure axis is fixed on the housing 1, the other end
It is fixed on center bearing bracket 2.In the present embodiment, the closure axis 34 is fixed on by rigid support 51 on the housing 1.
