The fixing slot (non-label) that component 100 coordinates.The connecting portion 322 includes connection sheet 324 and from the connection sheet 324 or so
The Extendible flake 325 that both sides are downwardly extending.Mounting hole 326 is offered in the connection sheet 324, the mounting hole 326 includes
Axis hole 327 and the escape groove 328 for tearing formation outward from the both ends of the axis hole 327.
Fig. 2 and Fig. 3 are referred to, the drive component that is closed includes 34 He of closure axis being mounted on the center bearing bracket 2
The closure nut 35 being arranged on the closure axis 34.Taper biography is provided between the closure axis 34 and closure transmission component
Moving gear group, the taper driving gear set include the first bevel gear 41 being arranged on the closure transmission component and setting
Second bevel gear 42 in the center bearing bracket 2 support, one end of the closure axis 34 is inserted into the second bevel gear 42
And pass through flat structure and connect.The closure axis 34 is used with the closure nut 35 being disposed thereon and is threadedly coupled, the closure spiral shell
The rotary motion for being closed axis 34 is converted into linear motion so that the closure nut 35 can be on the closure axis 34 by mother 35
It moves linearly along the longitudinally for being closed axis 34.The closure nut 35 is inserted into the mounting hole 326, the closure
It is clearance fit between nut 35 and mounting hole 326, the closure nut 35 drives the nail bin groupware stent 32 to be closed described
The longitudinally movement of axis 34 is closed described in 34 upper edge of sympodium.The closure nut 35 includes pressure section 351, is compressed described in
The axle portion 352 and the lateral convex block 353 formed from the 352 outside projection of axle portion that portion 351 is downwardly extending, the axle portion
352 are inserted into axis hole 327 so that the axle portion 352 coordinates with axis hole 327, are gap between the mounting portion and axis hole 327
Cooperation.When being closed nut 35 with the assembling of nail bin groupware stent 32, lateral convex block 353 is first aligned with escape groove 328, so that institute
It states 35 sets of nut of closure to be set on nail bin groupware stent 32, then, nut 35 will be closed and rotate so that the lateral convex block 353
It misplaces with escape groove 328, at this point, the connecting portion 322 of nail bin groupware 100 is clamped between pressure section 351 and lateral convex block 353,
It is detached to prevent non-magnetic shim storehouse assembly support 32 with being closed nut 35, simultaneously as the nail bin groupware stent 32 is with being closed nut 35 again
For socket, axle portion 352 is polished rod, mounting hole 326 is unthreaded hole, therefore can be opposite between nail bin groupware stent 32 and closure nut 35
Do the swing in slight amplitude.In the present embodiment, 32 relatively closed nut 35 of nail bin groupware stent rotates in order to prevent, institute
It states and fixing piece 36 is fixed on nail bin groupware stent 32, the card coordinated with the convex block 353 is provided on the fixing piece 36
Slot 361, the convex block 353 are located in the card slot 361, and the fixing piece 36 is located at the lower section of the connecting portion 322, in this reality
It applies in example, which welds with nail bin groupware stent 32.The fixing piece 36 is accommodated in nail bin groupware stent 32.It is described
Center bearing bracket 2 has accommodating second bevel gear 42, the accommodating cavity 21 for being closed axis 34, the side phase of left and right two of the accommodating cavity 21
To being provided with cavity wall 211, the connecting portion 322 is accommodated in the accommodating cavity 21, and the connecting portion 322 fits in described accommodating
In chamber 21 and the connecting portion 322 can move in the accommodating cavity 21 along the longitudinally for being closed axis 34.The connecting portion
322 two Extendible flakes 325 correspond to two cavity walls 211 and set respectively, and Extendible flake 325 is bonded to limit the nail with cavity wall 211
Storehouse assembly support 32 shakes in the left and right directions of nail bin groupware stent 32.In other embodiments, it is mobile smart in order to mention
Degree is provided with lead, and is provided on accommodating cavity 21 and connecting portion 322 with being somebody's turn to do between the connecting portion 322 and accommodating cavity 21
The arcuate guide hole of lead cooperation, so as to evade face contact, improves mobile accuracy.The arcuate guide hole, which is arranged on, prolongs
It stretches on piece 325, really, Extendible flake 325 can be not provided with, then the arcuate guide hole is formed directly into connection sheet 324.
Pre-bending shrapnel 37 is provided on the nail bin groupware stent 32, the pre-bending shrapnel 37 is clamped in nail bin groupware branch
Between frame 32 and housing 1, the pre-bending shrapnel 37 includes being located at the first sheet body portion 371, the setting of 324 top of connection sheet
The second sheet body portion 372 above the frame body portion 321 and the folding from the fold-down formation in the second sheet body portion 372
Portion 373, which is located at the lower section in the second sheet body portion 372, and the folding part 373 is set close to connection sheet 324, described
Folding part 373 supports frame body portion 321.There is folding line between first sheet body portion, the 371 and second sheet body portion 372.By following closely
Set pre-bending shrapnel 37 that can both prevent to generate between nail bin groupware stent 32 and housing 1 between storehouse assembly support 32 and housing 1
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.
The fixing groove (not shown) docked with the closure axis is recessed on the rigid support 51, it is in the present embodiment, described
Bearing 52 is provided between rigid support 51 and closure axis 34, the bearing 52 is arranged in the fixing groove.The rigidity branch
