Abstract

The invention discloses an electric chain saw chain tightness adjusting device. The electric chain saw chain tightness adjusting device comprises a machine frame, a chain wheel, a chain board and a chain. The chain wheel is connected on the machine frame in a rotating mode. The chain board is arranged on the machine frame. The chain is arranged on the chain board and driven by the chain wheel. An adjusting device is arranged on the chain board, and the adjusting device is used for adjusting the relative distance between the chain board and the chain wheel so that the chain can be loosened or tensioned. The adjusting device comprises a gear driving device and a position-limit device, wherein the gear driving device drives the chain board to move, and the position-limit device drives the chain board to move back and forth relative to the machine frame. By means of the electric chain saw chain tightness adjusting device, tightness of the chain can be conveniently adjusted, operability can be enhanced, and security risks can be effectively avoided.
