A reciprocating lead screw is fixedly connected to the output shaft of the motor, and a threaded block is threadedly connected to the circumferential surface of the reciprocating lead screw. In use, the rotational force of the connecting handle and the clamping block, telescopic rod, and fixed block inside the clamping device cooperate with each other to realize that the bidirectional threaded rod drives two threaded sleeves to move inward, thereby driving the fixed block and the placement plate to move inward as well.
