ABSTRACT:
A chain saw brake device that can instantly halt the rotation of a cutting chain when a motor drive switch is turned off. The chain saw brake device includes a brake band wound around a brake drum, such that by operating a hand guard and pulling the forward end of the brake band, the brake band is tightened around the brake drum, thereby stopping the cutting chain. The rear end of the brake band is fixed to a bent rod, and the bent rod is urged rearwardly by a coil spring when the drive switch is turned off, causing the brake band to tighten around the brake drum. By activating a trigger lever, the movable member, engaged with the trigger lever, is moved forwards, thereby pushing forwards the bent rod, and loosening the brake band.
