The working principle of a chain chainsaw is based on the power output of an internal combustion engine or an electric motor. When starting the chainsaw, the power source drives the chain on the guide plate to circulate at high speed. The saw teeth on the chain come into contact with the workpiece, and the workpiece is sawed off through high-speed friction and cutting force. The user controls the direction and angle of the electric saw through the handle to achieve precise cutting.

Chain chainsaw, also known as chainsaw or power saw, is a mechanical device that uses an internal combustion engine or an electric motor as the power to cut through high-speed circular motion of the driving chain. It has the characteristics of fast cutting speed, simple operation, and wide applicability, and is widely used in fields such as logging, pruning, and building demolition.
