ABSTRACT:
A miniature impact tool utilizes a cam for driving a striker forward by converting a rotary motion to a linear motion. The striker is spring loaded and is moved away from a surface to be struck during a portion of the rotation cycle of the cam. On further rotation the cam surface is cut away and spring action drives the striker forward causing impact. The above action is then repeated. The tool is adapted to be provided with variable drive speed and torque.
