[0002] A chain is a mechanical transmission device consisting of interconnected metal rings used to transmit power and motion in mechanical equipment, such as motorcycle chains, bicycle chains, and transmission chains in industrial machinery. The chain can bend and move in multiple directions to adapt to complex movement and layout requirements.

[0003] Regular chain lubrication is crucial for maintaining a secure chain connection. Lubrication reduces friction and wear between the links and pins, extending the chain's lifespan and maintaining optimal operating condition. Selecting the appropriate lubricant based on chain usage and environmental conditions, and lubricating regularly according to the manufacturer's recommendations, can improve chain stability and longevity.

[0004] Most of the devices usually use regular lubrication of the chain during use, but the lubrication area cannot be accurately controlled during use, resulting in some chain links and pins not being lubricated, which leads to breakage and loosening due to long-term wear during use.
