Inside cavity, second end 22 and ejector pin bar 75 contradict.At this point, instrument is in safety position.Due to the torsion of the second torsional spring 34
Much smaller compared with percussion force, the first in command 1, can be around the first rotation counterclockwise of pin shaft 31 in curable grip lesser by operator
Turning, second handle 2 goes successively to the inside cavity of the first in command 1, i.e. the first in command 1 and second handle 2 is in not linkage status,
Second handle 2 does not rotate.Operator hold with a firm grip the first in command 1 when, the first in command 1 can not made to rotate easily, but not
It will drive the rotation of second handle 2, be also just unable to complete the percussion of stapler.Operator can also obtain touch feedback at this time,
The first end 51 for solving current pointer 5 is not up to second position region, does not fire.When external force releases, the first in command 1 is the
It is resetted under the action of two torsional springs 34.
As shown in figure 12, the schematic diagram in second position region is moved to for the first end 51 of the pointer of the embodiment 5.The mistake
Cheng Zhong, turning knob 71 make screw rod 76 that pulling-on piece 6 be driven to move to the near end, and drive the first end 51 of pointer 5 along clockwise direction
It is mobile, so that the first end 51 of pointer 5 enters second position region from first position region.Therefore the second end 52 of pointer 5 pushes away
Movable slider 42 is mobile to the second segment 412 of sliding slot 41, so that the first position limiting structure 43 is close to the second position limiting structure 44, compression pressure
Spring 45 deforms.At this point, the handle abutting portion of second handle 2 will interfere with sliding block 42 in the rotating path of the first in command 1.
It is located at structure when cock such as handle assembly that Figure 13~15 show the embodiment.In 1 quilt of the first in command
When holding rotation counterclockwise, sliding block 42 and 2 abutting portion of second handle contradict and second handle 2 are stopped to go successively to the first in command
In 1 internal cavity.Second handle 2 and the first in command 1 become linkage status as a result,.Second handle 2 is with 1 inverse time of the first in command
Needle rotation, the second end 22 of second handle 2 push ejector pin bar 75, and ejector pin bar 75 can further push the pushing slice of nail and ring of stapler
Shape cutter is sutured and is cut to the tissue performed the operation.
It can be seen from the figure that pressure spring 45 is gradually compressed in the moving process of sliding block 42.Further, second handle
Pulling-on piece abutting portion 23 is additionally provided on 2, when second handle 2 is rotated from safety position to firing position, the meeting of pulling-on piece abutting portion 23 exists
It ejects apex and jacks up pulling-on piece 6, be detached from the drag hook of pulling-on piece 6 and pointer 5.At this point, pointer 5 restores in the counterclockwise direction to initial
Position.In this embodiment, a metal is provided at position corresponding with the first end 51 of pointer 5 in the shell 74 of stapler
Piece 77, when the recovery of pointer 5 to initial position, meeting and sheet metal 77 are hit, and be made a sound, and operator's pointer is prompted to reset.
Since the first end 51 of pointer 5 is back to first position region, in the second end 52 and sliding block for unclamping 1 backpointer 5 of the first in command
42 are detached from.Then, after the reset of pointer 5, since pointer 5 no longer has an active force to sliding block 42, pressure spring 45 is when restoring to the original state
Deformation force can push sliding block 42 to slide again to the first segment 411 of sliding slot 41, be restored to initial position.Second handle 2 also exists
Restore under the restoring force of first torsional spring 31 to initial position.The first in command 1 is due to being nibbled under the action of sliding block with second handle 2
It closes, therefore it is first as second handle 2 resets, while resetting under the action of the second torsional spring 34 again.
The utility model embodiment also provides a kind of stapler, including the handle assembly.It can not up to be hit in stapler
When hair-like state, the first in command will not drive second handle, would not also fire stapler, doctor can also by operating experience come
