[0023] In this embodiment, driven by the lifting assembly, through the rotation cooperation of the connecting rod 107 and the sliding pin 106, the sliding pin 106 drives the positioning rod 105 to rotate downward around the fixed block 104, and the four corners of the steel plate are fixed under the joint action of the four groups of positioning rods 105, so that the steel plate has a better fixing effect, the steel plate can reduce vibration, and the cutting effect of the steel plate is better.
