ABSTRACT:
A trigger-brake structure for tool machine comprises a trigger device and a brake device arranged in a machine base, in which the trigger device is employed for starting a power switch while the brake device for constraining the power transmission. The trigger-brake structure for tool machine is characterized in that a transmission axle for power transmission is arranged in the machine base; a leverage trigger of the trigger device will apply force to another lever in the brake device when the trigger is rotated to move a self-restoring switch to therefore start the power of the machine base; and, the brake device is comprised of a flange of a spring for receiving a force applied by the trigger through a lever so that the stretch degree of a spring leaf surrounding the transmission axle can be controlled by the trigger device to thereby change the frictional force of contact surface between the spring leaf and the transmission axle.
