ABSTRACT:
An ear piercing instrument that uses the gripping force of a hand to drive the earring post through the ear and into an earring nut. The earring and its nut are held in opposing jaws while the earlobe is placed between the jaws. When the ear is ready for piercing, the hand gripping the ear piercer is first tightened to bring the earring into closer proximity to the nut. A frangible tab holds the ear piercing process in abeyance until the hand squeezes sufficiently hard to break the frangible tab. Upon breaking the frangible tab, the earring and nut jaws are rapidly accelerated towards each other by the squeezing hand. The intermediate earlobe (or other body part) is pierced. With the insertion of the nut jaw into the earring jaw, a flexible tang catches the back side of the earring cartridge to expel it when the nut jaw is withdrawn from the earring jaw. A top gap is present in the earring jaw above and adjacent to the earring cartridge, allowing the use of ornamented earrings having hoop or other type of extensions.
