As more preferably technical solution, the auxiliary hold-down mechanism can drive clamping plate opposite direction to compress in driver plate
On the basis of, elastic compression further is carried out to clamping plate, improves the clamping effect of clamping plate, specific work process is as follows：When above pushing away
When arm and lower push arm are moved with the promotion of driver plate, since clamping plate has displacement straight up, so clamping plate drives hinge
Joint chair moves up, and relatively upper push arm makees the sliding of diagonal upward direction in the through-hole of upper push arm with the hinged slide bar of hinged seat, in turn
So that the holddown spring between upper push arm and hinged seat is compressed again, the elastic potential energy of holddown spring itself is converted into pressure
And it is transferred on clamping plate so that clamping plate further clamps object.
When needing clamping plate to be detached with object so that the output end for the part that moves along a straight line makees resetting movement, above-mentioned
The part that moves along a straight line can be the tools such as cylinder in the prior art, hydraulic cylinder or electric cylinder.
The utility model compared with prior art, has the following advantages that：
1）The utility model is simple in structure, only needs single driving member that the Bidirectional clamping to object can be realized, and grasps
Make simple and convenient；
