Abstract

The invention discloses an electric chain saw chain elasticity adjusting device. The electric chain saw chain elasticity adjusting device comprises a machine frame, a chain wheel, a chain board and a chain, wherein the chain wheel is connected with the machine frame in a rotating mode, and the chain board is arranged on the machine frame. The chain is arranged on the chain board and is driven by the chain wheel. The chain board is provided with an adjusting device, wherein the adjusting device adjusts the distance of the chain board relative to the chain wheel and enables the chain to be loosened or tensioned. The adjusting device comprises a worm and gear device and a limiting device, wherein the worm and gear device drives the chain board to move, and the limiting device moves forward and backward relative to the machine frame. According to the electric chain saw chain elasticity adjusting device, the elasticity of the chain can be adjusted conveniently, the operability is strengthened, and the potential safety hazard is 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 adjusting device, which can conveniently adjust the chain tension, enhance operability, and effectively avoid potential safety hazar...
