Description

Grease gun device capable of preventing grease from being mixed with sand to block tip nozzle

Technical Field

The invention relates to the technical field of motor vehicle maintenance, in particular to a grease gun device for preventing lubricating grease from being mixed into sand to block a tip nozzle.

Background

The parts in the motor vehicle are blocked frequently, and the parts are not flexible because the friction force is too large, at the moment, lubricating grease needs to be filled into mechanical equipment by means of a grease gun, the nozzle of the grease gun is replaceable, the use is convenient, lubricating grease only needs to be filled into a cylinder, and a lubricating oil nozzle is aligned to a part needing lubrication in west during use and is filled with the lubricating oil.

When tools such as maintenance are used, various types of grease guns are generally required to be adopted for different surfaces of mechanical equipment, a pointed grease gun is required to be adopted for corners with more secret gaps, the pointed grease gun can accurately solve the problem of the areas in the clamping gaps of parts such as handles and door seams, the spraying can be more delicate, the capacity of the pointed grease gun is finer, if sand is mixed into the grease carelessly, lubricating grease is concentrated at the spray head during spraying, if the sand mixed into the grease is also mixed into the grease gun, the spray head can be easily blocked after the grease gun is piled up for a period of time, and the solution is difficult to extrude.
