PURPOSE: An automatic grease gun is provided to smoothly supply grease, and to reduce manufacturing costs while a flexible cartridge is screwed to a container without an adapter. CONSTITUTION: An automatic grease gun(10) comprises a body(12), a decelerate motor(14), an actuating body(22), a plunger(24), a small screw pipe(30), and a big screw pipe(34). The decelerate motor is fixed to one upper side of the body. The power of the decelerate motor is delivered to the actuating body through a rotator(18). The actuating body reciprocates inside an actuating chamber of a case(20). The plunger is connected to the actuating body, and coupled to a compression chamber placed on the other side of the body. The grease supplied through an inlet(26) of the compression chamber is compressed. The small screw pipe is protruded from a rim of the inlet of the compression chamber, and screwed to a flexible cartridge(28). The big screw pipe is protruded from the rim of the small screw pipe, and connected to a container(32). |
