The bottom walls of the two shift blocks 12 are connected to the outer wall of the connecting sleeve 9 on the same side through a fixing mechanism. The fixing mechanism includes a fixing spring 13 installed on the outer wall of the fixing pin 11, and the two ends of the fixing spring 13 are elastically connected to the outer wall of the connecting sleeve 9 and the bottom wall of the shift block 12 respectively. A clamping plate 14 is fixedly installed at the end of the two connecting rods 10, and a second anti-slip pad 15 is fixedly installed on the inner walls of the two clamping plates 14. A sliding rod 16 is fixedly installed on the upper end surface of the processing table 1 through a sliding opening, and a support plate 18 is slidably installed on the outer wall of the sliding rod 16 through a stabilizing mechanism. The stabilizing mechanism includes a stabilizing rod 17 fixedly installed inside the movable opening, and the stabilizing rod 17 slides through the support plate 18.
