PURPOSE: An automatic lead injector is provided to reduce fatigue and prevent a burn since lead injection is automatically controlled from the side. CONSTITUTION: An automatic lead injector comprises a plastic container(110), a lead transfer pipe(120), an incline(135), engaging members(140,150), an upper protrusion(145), a lower protrusion(155), an engaging clutch(170), and a lead control knob(130). A lead outlet is coupled with the plastic container. The lead transfer pipe transfers lead. The incline presses the lead of the lead transfer pipe from the side. The engaging member accepts the incline. The upper protrusion and the lower protrusion guide a return after the up and down movement of the upper and lower engaging members. The engaging clutch connects the upper engaging member and the lower engaging member. The lead control knob has the incline and adjusts the engaging member to discharge lead forward. |
