[0016] The application has the following beneficial effects:

[0017] The automatic avoiding function between the chain and the component is realized, the oil guide block is separated from the chain through the action of the elastic element in the initial state, unnecessary friction is avoided, and the chain is ensured to freely run in a non-maintenance working condition.

This effectively reduces friction, improves lubrication, avoids frequent manual lubrication, and enhances maintenance efficiency. Attached Figure Description
