Abstract

The invention discloses a chain saw. The chain saw comprises a guide plate for the chain saw, a shell, a protection cover mounted on the shell, and at least one fastening bolt fixed to the shell. Each fastening bolt is provided with a first limiting step. Threads are arranged on the upper portions of the first limiting steps. Fastening nuts are assembled to the fastening bolts. The distances H1 from bottom threads of the fastening nuts to the bottoms of the nuts are smaller than the distances H3 from the first limiting steps to the guide plate during assembly. The chain saw has the advantages of capability of preventing the chain saw from being used without mounting of the protection cover and from injuring operators, simple structure, safety and reliability.
