ABSTRACT:
A grease gun plunger for a grease gun having an oil injection channel includes a motor driving unit, a plunger unit, and a yoke. The plunger unit includes a bracket having a bracket cavity and an elongated slot longitudinally formed on a rear wall of the bracket to communicate with the bracket cavity, and a plunger pin downwardly extended from the bracket for slidably inserting into the oil injection channel. The yoke, which is substantially held in the bracket cavity of the bracket, has a sliding channel aligning with the elongated slot of the bracket, wherein the driving shaft is slidably inserted into the sliding channel through the elongated slot in such a manner that when the driving shaft is rotated to slide along the sliding channel, the yoke is driven to move in a reciprocating manner along a transverse direction.
