At the same time, the second servo motor is started again. The second servo motor drives the second threaded rod to rotate. The rotation of the second threaded rod causes the second slider to move longitudinally, so that the second slider moves laterally and longitudinally. The second slider drives the first hydraulic rod to move. The first hydraulic rod drives the clamping mechanism and the length adjustment mechanism to move longitudinally, so that the movement of the base plate frame can be accurately controlled to move in all directions.

[0015] (2) The utility model drives the bidirectional threaded rod to rotate by operating the third servo motor. Since the threads at both ends of the bidirectional threaded rod are in opposite directions, the two third sliders will approach each other. The two third sliders drive the length adjustment mechanism at the bottom to approach each other, thereby fixing the bottom plate frames of different widths.

[0016] (3) The utility model drives the fixing block to move through the second hydraulic rod, and the fixing block drives the top end of the connecting rod to move.
