[0013] Further, the outer circumferential surface of the fixed rod is provided with a sliding groove, and the inner wall of the sleeve is fixedly connected with a sliding plate, and the sliding plate is slidably connected with the fixed rod through the sliding groove.

[0014] Through the above scheme, the sleeve is limited, so as to avoid the sleeve driving the first sliding plate or the second sliding plate to rotate on the outer circumferential surface of the fixed rod, and make the sleeve always move transversely, so as to improve the stability of the movement of the first sliding plate and the second sliding plate.

[0015] Further, the inner part of the transmission wheel is provided with a limiting groove, and the transmission belt is located in the limiting groove.

[0016] Through the above scheme, the transmission belt is limited, so as to avoid the transmission belt easily falling off from the transmission wheel, and improve the stability of the movement of the transmission belt.

[0017] Further, the transmission belt is made of PU material.

[0018] Through the above scheme, the transmission belt made of PU material has more excellent wear resistance and anti-aging performance, and the transmission efficiency is higher, which can maintain high transmission efficiency in high-precision, high-load and high-speed transmission system, and ensure the stability of transmission.

[0019] Further, the two sides of the first sliding plate and the second sliding plate are fixedly connected with mounting plates, and equidistantly arranged positioning bolts are threadedly connected in the mounting plates.
