Abstract
A chain including chain-link units pivotally connected with each other. Each chain-link unit includes two lateral plates, a first link plate and a second link plate. Two ends of the lateral plates are defined as a first end and a second end. Two first pin-joint parts are configured near the first ends of the lateral plates respectively, and two second pin-joint parts are configured near the second ends of the lateral plates respectively. The chain-link units are pivotally connected with each other via the first pin-joint part and the second pin-joint part. Thus, the chain-link units are common, and each can be the starting chain-link unit, the middle chain-link unit or the ending chain-link unit. They can be easily assembled without screws, which further reduce the time consumption. Moreover, the noise made as the chain works can be reduced, and a buffering function can also be provided.
