Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a piercing device using a cartridge, in which a pin having a decorative head and two sets of stoppers fitted to the pin for stopping the decorative head on an earlobe are housed. .

[0002]

2. Description of the Related Art A pair of sterile earrings
Cartridges for piercing the earlobe are known, for example US Pat. Nos. 4,030,507 and 5,035.
No. 007,918. The above two inventions use a housing having two cylindrical chambers that house two earrings in parallel and an oval wall that houses two wire nuts. The housing is removably fitted into a holding recess provided in the plunger assembly, and in the fitted state, the housing is pushed from above so that the flange at the rear end of the housing engages with the holding plate of the recess. Drop it. Arranged on the movement axis of the plunger is the upper chamber of the housing, insert the earrings inside it into the earlobe, then reverse the top and bottom of the housing and insert the second earring into the earlobe. . The wall body containing the wire nut fixed to the above earring is attached by inserting the left and right parallel legs into the opening formed in the support body, and the wall nut can be moved up to move the lower wire nut. Remove the body from the support, turn it upside down and attach it again.

Thus, conventional cartridges that use two sets of piercing earrings must be carefully attached to the mounting location of the plunger assembly before piercing the individual earrings. In other words, in order to attach the cartridge, it is necessary to once pinch the cartridge with a fingertip, turn it upside down, and attach it again. Such an operation is tedious and also creates an opportunity to contaminate sterile earrings and wire nuts with bacteria. To eliminate the opportunity for contamination, the piercing device used by one person must not be reusable. This is because even if there is no opportunity to touch the earrings, wires, nuts, etc., blood may adhere to the piercing device when it is pierced into the earlobe, or may be contaminated with bacteria during repeated use. However, in the conventional piercing system, the body incorporating the plunger assembly has a reusable structure as long as the cartridge is replaced. Sterility is not guaranteed with such conventional piercing systems.
