SCREW DISJOINTING APPARATUS FOR EASILY DETACHING SCREW WITH BROKEN HEAD

摘要

PURPOSE: A screw disjointing apparatus is provided to easily detach a screw from a part without the breakage of the part when the head of the screw is broken partially. CONSTITUTION: A screw disjointing apparatus is composed of a main rod(100), a fixing mount(200) installed at one end of the main rod and fixed to one side of a part, a push rod(300) installed at the other end of the main rod, a bit, a bit holder(440) for holding the bit, and a rotary handle. The bit is installed between the fixing mount and the push rod of the main rod, and is engaged with a screw mounted to the part. The bit holder penetrates through the main rod vertically, and is coupled to the main rod. The rotary handle is coupled to the top of the bit holder and rotates the bit. A sliding groove(110) is formed longitudinally on the main rod. The bit holder is fit into the sliding groove by a bit holder supporter, and slides along the main rod longitudinally.
