The chain shaft on the first drive link is riveted to the chain hole on the adjacent second drive link, and the chain shaft on the second drive link is riveted to the chain hole on the adjacent first drive link.

[0013] By adopting the above solution, riveting is achieved, and fewer components are used, resulting in lower costs.

[0014] Furthermore, the chain shaft is made of carburized steel.

[0015] By adopting the above solution, the fatigue resistance and wear resistance are improved.

[0016] Furthermore, the cutting teeth are integrally formed with the second transmission piece.
