[0032] Start the hydraulic cylinder 38. The hydraulic cylinder 38 drives the slider 37 on the left side to move. When the slider 37 on the left side moves, it drives the connecting plate 36 on the left side to move, and then drives the Z-shaped plate 35 to move. When the Z-shaped plate 35 moves, it drives the connecting plate 36 on the right side to move synchronously. When the connecting plate 36 on the right side moves, it drives the slider 37 on the right side to move. When the two sliders 37 move synchronously, they drive the connecting rod 39 to slide on the inner wall of the chute 310. When the connecting rod 39 moves, it drives the arc-shaped fixing plate 311 to move, so that the arc-shaped fixing plate 311 is engaged with the groove 312 to clamp and fix the groove 312. At the same time, the arc-shaped fixing plate 311 and the connecting body 1 are further fixed by bolts 313.
