With reference to Fig. 3~5, when movable part 100 is mounted on fixing piece 200,211 one end of fixed pin is stuck in arc chute
In 111, when 100 opposed fixed member 200 of movable part rotates, arc chute 111 is rotated with movable part 100, and fixed pin 211 can be in arc
It is slided in shape sliding slot 111, when the position where the first end 111a of arc chute 111 turns to fixed pin 211, fixed pin
211 pairs of arc chutes 111 carry out stop /V so that 100 stop motion of movable part, powerless in linkage and torque work
With movable part 100 is located at the first extreme position at this time, and linkage stops driving traction piece movement；It is backhauled when movable part 100 is past
It is dynamic, when 111 second end 111b of arc waist-shaped hole reaches the position where fixed pin 211, fixed pin 211 to arc chute 111 into
Row stops /V so that 100 stop motion of movable part, powerless in linkage and torque effect, at this time movable part 100 be located at
Second extreme position, linkage stop driving traction piece movement.In the present embodiment, fixed pin 211 is in position limiting structure
Limited block, arc chute 111 collectively constitute the position limiting structure of the present embodiment with fixed pin 211, for limiting turning for movable part 100
Dynamic angle, makes movable part be limited between the first extreme position and the second extreme position and moves, and realizes position-limiting action.
In technical scheme, position limiting structure directly carries out /V to movable part 100, is limited with setting in the prior art
The scheme that bit slice carries out sliding block /V is compared, and in the technical solution of the prior art, banking stop is set to carry out /V to sliding block, i.e.,
/V is carried out to transmission mechanism end, reaction force acts make transmission mechanism generate excessively in entire transmission mechanism
Loss, long-time service will cause transmission parts to generate loosening, and the present invention is equivalent to directly to this 100 direct /V of movable part
The force application part of lift pincers transmission mechanism carries out /V, when movable part 100 reaches above-mentioned two extreme position, linkage 300
In powerless or torque application, avoid impact of the reaction force to whole transmission mechanism, reduce the loss of transmission parts, solve length
Phase leads to the problem of loosening using rear lift pincers transmission mechanism and causes movement transmission inaccurate, and lift is avoided to clamp transmission mechanism and is transported
Dynamic deviation so as to extend the service life of lift pincers transmission mechanism, improves the stability and sensitivity of lift pincers device.And without setting
For limiting the banking stop of sliding block movement, transmission mechanism can be simplified.
Fig. 6 clamps the assembling schematic diagram of movable part and fixing piece one embodiment in transmission mechanism, reference chart for present invention lift
2nd, 6, when movable part 100 is mounted on fixing piece 200, resigning step 112 and above-mentioned 212 position of resigning breach are corresponding, and two
Person forms one and allows bit space A so that when linkage is fixed on movable part 100, swing rod 320 can allow at this in bit space A
Activity, this allows bit space to provide space for the movement of swing rod, avoids linkage 300 and fixing piece 200, movable part
It is interfered between 100.
