At this time, the two relative clamping frames 410 approach each other until the two clamping frames 410 cooperate to clamp the guide rail workpiece, and the push plate 409 continues to move. At this time, the pressure plate 404 continues to approach the guide rail workpiece, and the movable pressure plate 404 uses the vertical rod 412 to push the sliding rod 413 on the rotating plate 411 to move inside the clamping frame 410, and the sliding rod 413 drives the side plate of the slip ring 414 to slide on the surface of the inner rod 416 of the side groove, and the two relative slip rings 414 cooperate with the extrusion spring 415, and use the elastic force of the spring 415 to prevent the clamping frame 410 from causing pressurization damage to the guide rail workpiece, until the two pressure plates 404 cooperate to clamp the guide rail workpiece, completing the limitation of the guide rail workpiece, and avoiding the guide rail workpiece from being offset during the stamping process.
