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.

Description

technical field [0001] The invention relates to a device for adjusting the chain tension of an electric chain saw. Background technique [0002] The electric chain saw is a relatively dangerous tool. Generally, users need to be trained. Even so, there will be safety accidents. Among them, the chain is loosened or even detached from the chain due to the severe vibration of the electric chain saw during use. Injury accidents caused by boards occur from time to time. In addition, with the development of the times, the application fields of electric chain saws are becoming wider and wider, and more and more people use them, which puts forward higher requirements for the safety and operability of chain saw design. Contents of the invention [0003] The problem to be solved by the present invention is to provide an electric chain saw chain tension adjustment device, which can conveniently adjust the chain tension, enhance operability, and effectively avoid potential safety haza...
