Further, described grease gun also comprises operating device, described operating device comprise the handgrip hinged with first plunger, with the hinged connecting rod of handgrip, the rifle body of the connecting rod the other end and grease gun is hinged.
Preferably, described first plunger pump, the second plunger pump subtend are arranged at the upper and lower side of shoe cream room, and described link is to be connected between first plunger and second plunger in flakes.
Preferably, be provided with vent valve on described first passage, the second channel.
Preferably, be provided with one-way valve on the connecting passage of described first oil cylinder, second oil cylinder and oil outlet.
Preferably, described first plunger pump, second plunger pump vertically are provided with.
Technical conceive of the present utility model is: grease gun is provided with first, second plunger pump, first, second plunger links by link, be implemented in reversing motion in the oil cylinder separately, first plunger inwardly advances, oil is gone out in first oil cylinder to extrude, meanwhile, second plunger is then outwards pulled out, and oil enters in shoe cream room second oil cylinder.Usually by in first, second plunger is carried out combined operation, like this, no matter carry or pressing action on the handgrip, can both realize fuel-displaced, the oil yield efficiency height.
After adopting said structure, the utility model is compared the advantage that is had with prior art and is: fuel-displaced frequency is fast, high working efficiency, time saving and energy saving.
