[0028] The upper and lower parts of the slide seat 3 are both provided with linear slide rails 5 slidably connected thereto, and the linear slide rails 5 are fixedly installed.

[0029] Each slide seat 3 is correspondingly provided with two linear slide rails 5 , and the two linear slide rails 5 are arranged in parallel, and the slide seat 3 can slide back and forth along the linear slide rails 5 .

[0030] The side of the slide 3 is fixedly connected with a horizontally arranged adjusting rod 9, the adjusting rod 9 and the slide 3 are arranged in a one-to-one correspondence, the axis of the adjusting rod 9 and the axis of the rotating shaft 2 are arranged to intersect vertically, and the adjusting rod 9 is arranged in parallel on both sides of the sprocket 1.

[0031] The main body of the adjusting rod 9 is inserted into the fixing seat 12, and the fixing seat 12 is fixed. A linear bearing 13 is fixed inside the fixing seat 12, and the linear bearing 13 is sleeved on the adjusting rod 9. The two ends of the linear bearing 13 are flush with the two surfaces of the fixing seat 12. The linear bearing 13 is used to support and guide the adjusting rod 9 so that it remains stable and smooth during movement.

[0032] The end of the adjusting rod 9 away from the sliding seat 3 is connected to the sliding plate 10 through a connecting cylinder seat 11. The connecting cylinder seat 11 is provided with threads inside and multiple bolt holes outside. The inside of the connecting cylinder seat 11 is threadedly connected to the end of the adjusting rod 9, and the outside of the connecting cylinder seat 11 is fixedly connected to the sliding plate 10 by bolts.
