[0017] By adopting the above technical solution and providing support legs, the base can be stably supported.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0019] 1. In the present application, the driving wheel is first rotated, and the rotation of the driving wheel drives the threaded push rod to rotate. The rotation of the threaded push rod drives the connecting plate to move by using the threaded sleeve. The movement of the connecting plate drives the clamping block to move. The movement of the clamping block drives the clamping structure to clamp the workpiece. When the clamping structure needs to be replaced, the threaded plug rod is driven to rotate by pushing the ball. The threaded plug rod rotates and uses the socket to move away from the clamping block to cancel the fixation of the clamping block. Then the clamping block is removed from the fixed plate. Then the arc splint or concave splint is replaced, and the clamping block on the arc splint or concave splint is sleeved on the surface of the fixed plate. Then, the pushing ball is rotated in the opposite direction. The pushing ball rotates to drive the threaded plug rod to rotate.
