摘要： The present invention provides a chain saw, which includes a housing, a driving assembly mounted on the housing, a guide plate extending outward from the housing, a chain arranged on the guide plate and driven by the driving assembly, and a tension assembly for tightening the chain. The tension assembly includes an operating member and a driving member driven by the operating member, the driving member cooperates with the guide plate, and when a driving force is applied to the operating member, the driving member is driven and the guide plate is moved to tension the chain, and after the chain is tensioned, if the driving force is continuously applied to the operating member, the operating member disengages with the driving member, and the operating member continues to move to compress the guide plate.
