Torque control device for an electrically-driven tool

摘要

The present invention is directed to a torque control device for an electrically driven tool. The torque control device includes a stationary cam rotatably and detachably connected to an output shaft and a movable cam adapted to be rotatably and slidably engaged by said stationary cam. An adjustable screw cover is provided for adjusting the compression force of a spring against the movable cam thereby regulating the torque acting on the driven tool. The slidably connection between the stationary cam and the movable cam enables the releasing of the rotational force supplied to the stationary cam when the load on the driven tool exceeds a predetermined set torque.
