ABSTRACT:
In response to actuation of a trigger, a spring loaded shaft drives an ear piercing dart through an earlobe disposed intermediate a pair of positioning guides. The stem of the dart is retained by a clamp, one positionable member of which is attached to one end of a torque rod rotatably mounted within the shaft and the other member is attached to the shaft. Upon rotation of a knob attached to the other end of the torque rod to a detent position, a torque is applied to the torque rod to urge the clamp into securely engaging the stem of the dart. The knob also serves as a means for cocking the shaft. On actuation of the trigger resulting in translatory movement of the shaft and knob and piercing of the earlobe by the dart, means are provided for automatically releasing the knob from the detent position and freeing the dart from the clamp.
