PURPOSE: A mechanical pencil core removal auxiliary tool is provided to give stability in removal of a graphite core and remove inconvenience generated in a graphite removal process. CONSTITUTION: A mechanical pencil core removal auxiliary tool is equipped with a parting line(201) in a fan shape starting from the center; and a hole(202) where a graphite core is inserted. The mechanical pencil core removal auxiliary tool can remove the graphite core, which is shortened, through the interaction of the hole and a supplement support. The mechanical pencil core removal auxiliary tool fixes the graphite core in an appropriate size approximately ranged from 0.3 to 1.0 millimeter using an assisting handle(204). The mechanical pencil core removal auxiliary tool is adjustable from the maximum inner hole of 1.0 millimeter to 0.3-0.5 millimeters. Some mechanisms including two of assisting supports and the directly contracted surface are composed of the material with high friction like rubber.
