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.

Dependent claims

A piercing apparatus that uses a cartridge which couples a front member and a back member which can move close to and away from each other;

this device has a piercing needle and a fastener connected to the needle, and the piercing needle is shot through an earlobe to mount a pierced earring with the fastener, the piercing apparatus further consists of:
a hollow main body with a grip for one hand at the lower part of the apparatus, and a mounting portion to mount a back member in the cartridge in the forward portion;
a trigger with a supporting member which extends forward to mount the front member in the cartridge, and is spring-loaded forward in order to dispose the front and back members of the cartridge at separate positions;
a shooting-out shaft which can be operated from the outside, and can move back and forth behind the mounting portion in the main body, and press the piercing needle in the cartridge out at the pointed end;
a spring where pressure is stored by an operation to move the shooting-out shaft backward;
an anchoring member spring-loaded in the same direction as the shooting-out shaft in order to anchor the shooting-out shaft at the position where pressure is stored;
and
a releasing means disposed in the forward or backward position with respect to the anchoring member, and provided to engage with the anchoring member to release the anchorage of the shooting-out shaft as the front member comes close to the back member by means of an operation of the trigger, said releasing means further comprising means for rapidly increasing torque acting against said operation of the trigger.
