[0023] (III) Beneficial Effects

[0024] This application provides a detachable chain. The beneficial effects are as follows:

[0025] 1. For this detachable chain, by setting the fixing mechanism, the screw inserted into the threaded hole is rotated to move it down to the threaded groove opened at the top of the rotating shaft in the rotating hole until the bottom of the screw fits with the bottom of the threaded groove. Continuing to rotate the screw drives the rotating shaft to rotate. The rotation of the rotating shaft drives the block to move out of the upper cavity and then snap into the lower cavity opened on the side of the bottom groove along the chute, thus completing the installation of the chain. This reduces the installation steps of the chain, shortens the time consumed for chain installation, improves the convenience of chain installation, enhances the stability of chain connection, and extends the service life of the chain.

[0026] 2. For this detachable chain, by setting the drain outlet, the rainwater adhering to the surface of the chain and gathering in the lower cavity on one side of the bottom groove is discharged along the drain outlet, reducing the possibility of chemical reactions caused by long-term contact between moisture and the chain, which may lead to corrosion at the chain connection. This enhances the service life of the parts at the chain connection and ensures the stability of the chain connection. BRIEF DESCRIPTION OF THE DRAWINGS
