Braking system of chain saw

摘要

A braking system including a sensing lever operated when the forward portion of a chain saw moves upwardly with a jerk due to a kickback phenomenon or the hand of an operator slips from a handle during operation, a brake device, and a direct-acting interlocking member connecting the sensing lever to the brake device. A force exerted on the sensing lever and a force of a spring locking the sensing lever are both transmitted to the brake device through the interlocking member.
