[0026] See also Figure 1-4 A chain with a toothed portion, comprising a link mechanism 1 and a connecting plate 2, wherein the link mechanism 1 and the connecting plate 2 are hinged to each other to form a chain, the link mechanism 1 comprises mutually symmetrical link guards 101, a connecting shaft 102 is installed between the link guards 101, an outer surface of the connecting shaft 102 is provided with anti-skid teeth 103, and the anti-skid teeth 103 are equidistantly and cyclically distributed on the outer surface of the connecting shaft 102;

[0027] The connecting plate 2 is hinged to the outer surface of the link guard plate 101 through the connecting shaft 102 .

[0028] Through the above technical solution, anti-skid teeth 103 are set on the outer surface of the connecting shaft 102. The added anti-skid teeth 103 increase the friction force of the outer surface of the connecting shaft 102, thereby reducing slippage at the meshing point when the connecting shaft 102 meshes with the gear, thereby achieving the effect of improving the chain transmission efficiency.

[0029] Specifically, the middle of the connecting shaft 102 is a thick cylinder, and both ends of the connecting shaft 102 are thin cylinders.
