[0020] When in use, the upper clamping plate 32 is controlled to move upward, and the upper clamping plate 32 drives the two sliding columns 34 to slide inward through the sliding groove 33. The ends of the sliding columns 34 are embedded in the inner grooves of the sliding grooves 33. The two sliding columns 34 drive the two connecting rods 35 to rotate around the hinge axis and gradually tend to be vertical. The hinge axis drives the slider 36 to slide vertically in the groove plate 37. The hinge axis drives the lifting plate 38 and the clamping rod 39 to rise.
