The utility model sets a servo motor to drive the bidirectional screw to rotate. With the cooperation of the threaded hole, the bidirectional screw drives the sliding plate to move, thereby causing the sliding plate to move in the approaching direction, and the sliding plate drives the moving block to move. It is necessary to place the CNC workpiece on the top of the processing table in advance so that the CNC workpiece is located between the moving blocks. The movement of the moving block can clamp and limit the CNC workpiece. The worker manually turns the hand wheel, and then the hand wheel drives the unidirectional screw to rotate, and at the same time solves the problem of the need for a clamp to clamp and fix the workpiece during CNC processing. However, most of the existing clamps used for CNC processing clamp and fix the workpiece on both sides. During CNC processing, the workpiece is prone to up and down deviation, resulting in poor workpiece processing accuracy. The above-mentioned device device is centrally fixed from the front and back sides, while the positions of the left and right sides are not limited, resulting in a certain error in the fixed position of the device, and after the device is fixed, the position of the device cannot be moved, affecting the overall processing of the device.
