摘要： A power tool includes a braking system that minimizes a stopping time for a cutting blade of the power tool. The braking system includes a roller bearing clutch mechanism combined with a positive stop pin. The stop pin is provided at an end portion of a cable assembly. The cable assembly is coupled to a trigger through a lever on one end, with the stop pin and a return spring inserted into a gear box on the other end. When the trigger is in a released position, the stop pin fully engages into a positive stop on a bearing cage at a top portion of the drive assembly. The coiled return spring keeps the stop pin in position. When the trigger is pulled, the cable pulls the stop pin out of the positive stop.
