Abstract: A trigger switch device of power tool for preventing accidental triggering is disclosed, comprising a trigger, provided at front end of the handle of power tool, and a safety switch, provided at a side of the handle; when neither the trigger nor the safety switch is operated, the safety switch locks the trigger so that the trigger cannot pressed; when the safety switch is pressed, the lock on the trigger is released and the trigger can be pressed. When the safety switch is released with the trigger pressed, the safety switch locks the trigger so that the trigger remains in the pressed state; when the trigger is in the pressed state and the safety switch is operated, the trigger is unlocked and automatically returns to the original non-pressed position and the safety switch locks the trigger again. As such, the trigger cannot be pressed to prevent accidental triggering.

Abstract: A hedge trimmer includes elongated upper and lower blades overlapping relative to each other, each of the blades including a trimming portion having an outer periphery formed with a plurality of trimming edges and a mounting portion formed with a guiding hole; upper and lower eccentric wheels that extend into the guiding holes of the blades and that is formed with an eccentric hole respectively; and a brushless motor including an output shaft extending into and operably coupled with the eccentric holes in the eccentric wheels such that activation of the motor results in rotation of the eccentric wheels within the guiding holes in the blades, thereby driving the blades reciprocally relative to each other along their longitudinal direction.
