The invention relates to a hand-operated butter absorbing and injecting gun which is an improved common pressure lever type butter gun. With the basic structure of the common pressure lever type butter gun, the invention has the improvement that a rotary plug is arranged in a cylinder body at the front end of an absorbing and injecting oil cylinder. The rotary plug is provided with an inlet oil route and an outlet oil route, wherein, one end port of both the inlet oil route and the outlet oil route is opened on the upper head surface of the rotary plug, and the other end port is opened on the lateral wall of the rotary plug. The two end ports of both the inlet oil route and the outlet oil route are respectively connected with two oil through holes positioned on the body of the absorbing and injecting oil cylinder. The inlet oil route and the outlet oil route are respectively provided with a unilateral valve, and the two unilateral valves are reversely arranged. Solving the problems of inconvenience, insanitation and large waste when the prior butter gun is filled with butter, the invention is widely applicable for feeding butter to the mechanical equipment such as vehicles, agricultural machines and construction machinery.
Description
(1) Technical field: [0001] The invention relates to an improvement technology of a grease gun. (two) background technology: [0002] At present, the grease guns of similar products are mainly pressure rod type grease guns. Its basic structure includes a suction oil cylinder. The oil hole, the two oil holes are respectively connected to the oil injection nozzle and the oil storage tank. When using the ordinary pressure rod type grease gun to fill the butter, the oil storage tank must be removed, and the butter must be manually loaded, which is time-consuming, laborious, inconvenient, and unhygienic. If you are not careful, the butter will be spilled, causing waste and polluting the environment. (3) Contents of the invention: [0003] The purpose of the present invention is to solve the problems of time-consuming, inconvenient, unhygienic and wasteful filling of butter in the existing pressure rod type grease gun, and to provide a novel manual suction grease gun. [0004]...
