After long-term use, the chain is easy to fall off the sprocket, and the upper scraper ring stops working. If the scraper ring happens to stop in the high temperature area, it will be damaged.

[0004] Therefore, it is necessary to propose an upper scraper ring driving device to solve the above problems. Utility Model Content
