ABSTRACT:
A lubricant gun includes a housing, a lubricant reservoir, a motor, a final driver, an elongate eccentric seat, a guiding shroud, and a plunger. The elongate eccentric seat is mounted within the housing, and has a first portion connected eccentrically to the final driver, and a second portion opposite to the first portion. The guiding shroud is disposed between the elongate eccentric seat and a longitudinal slide channel within the housing, and defines a guide passage aligned longitudinally with the slide channel. The plunger has a guiding portion pivotally mounted to the second portion and slidably received in the guide passage, and a pushing portion received slidably in the slide channel. The guiding portion is guided by the guide passage when the plunger is driven by the elongate eccentric seat to reciprocate the guiding portion and the pushing portion of the plunger.
