The elastic cylindrical pin 6 is fitted with the integral locking pin holes. The elastic cylindrical pin 6 can adopt a spiral main body connecting column or other columnar structures with elastic effects. During use, the elastic effect enables a certain deformation space at the mating position during disassembly and assembly, making the combined operation during assembly more convenient. Lubrication mating grooves are provided on the elastic cylindrical pin 6, enabling lubrication mating as needed and enhancing the overall durability during use. By providing anti-rotation mating planes on both the sleeve and the pin shaft that cooperate with the link plate, it can ensure smoother operation of the chain during use, higher mating safety between link sections, no rotation during use, and avoid the occurrence of easy wear during use.
