The anti-fall pulleys on the existing market have complex structures, which are prone to improper operation during use, ultimately leading to safety accidents. At the same time, the current anti-fall pulleys will get stuck and unable to move when encountering the fixing components on the cable. Therefore, it is necessary to design an anti-fall pulley with a simple structure that can quickly pass through the fixing components on the cable. Summary of the Invention

A plurality of the same protruding components are integrally connected to the peripheral edge of the through hole. Arc grooves are provided at the same position on the surfaces of the protruding components. The protruding arc components are at least mutually engaged with 2 adjacent arc grooves. The rotating shaft is fixedly connected to the two side fixing baffles and the middle suspension member through the through hole.
