ABSTRACT:
The present invention presents a piercing apparatus that pierces an earlobe with a piercing needle integrated in a cartridge, and fastens the needle by using a fastener. One of the objects of this invention is to distinguish clearly in the initial operation the position pierced that will be, the needle is actually shot through the earlobe. The piercing apparatus has a piercing needle (1) integrated in a cartridge (C) and a fastener (2) which is attached to the needle. The needle (1) and the fastener (2) are respectively mounted at the forward and backward positions of the piercing apparatus' main body (10) and can move toward and away from each other. A trigger (14) is springloaded with a spring to keep the above separated positions, and is pressed to release the shooting-out shaft (15) through a releasing means (18) in order to shoot the piercing needle (1) Then, the releasing means (18) are disposed at the forward and backward positions with respect to the anchoring member (17), on the trigger side and the anchoring member side, respectively. Torque remains small and does not engage the releasing means (18) when the position to pierce is being determined, and the torque increases due to the engagement. In this way, one can be certain that the piercing needle (1) is ready to shoot out.
