The chain chainsaw mainly consists of power source, guide plate, chain, handle, and other parts. Power sources usually use internal combustion engines or electric motors, which have the characteristics of high power and stable performance. The guide plate serves as the track for chain movement, ensuring the stability and cutting accuracy of the chain. The chain is the core component of a chainsaw, and the sharpness and wear resistance of its teeth directly affect the cutting effect. The handle design is reasonable and convenient for users to operate and control.
