[0022] By adopting the above technical solution, the operating screw is rotated to move the operating screw toward the sliding rod so that the operating screw can abut against the driving surface, so that the sliding rod is subjected to a force in the direction away from the bottom of the sliding hole, thereby making the sliding rod abut against the side wall of the side plate, so that the top support rod and the side plate can be relatively fixed, thereby reducing the possibility of the top support rod moving relative to the support block along the length direction of the support groove, which is beneficial to improving the stability of the top support rod fixation.

A gap is provided between the abutting rod 512 and the inner side wall of the receiving groove 12 and the upper surface of the support block 5, so that the end of the top support rod 4 can be placed on the upper surface of the support block 5 from top to bottom.
