It is suitable for automobile axle manufacturers to quantitatively add grease to automobile wheel hubs, axles, axle boxes, and wheel hub bearings. It is also suitable for greasing rolling bearings of large vehicles such as automobiles, railway passenger cars, insulation vehicles, and subway vehicles. It is also suitable for motor manufacturers to add grease to motors, and hardware tool manufacturers to add grease to hardware tools. The grease injection head is an important part of the grease injection machine. The grease injection head can control the grease injection speed and grease injection amount of the grease injection machine, and the grease injection head is needed during the use of the grease injection machine.

The existing grease injection machine head is inconvenient for users to disassemble and assemble it, and it takes a lot of time and effort. At the same time, the grease injection machine head does not have the ability to protect the grease injection machine head and nozzle when not in use, which can easily lead to dust entering the nozzle of the grease injection machine head. If dust accumulates, it will affect the subsequent grease injection speed and effect, and bring trouble to the user's installation work. Therefore, we need to upgrade and transform it based on the existing technology. Utility Model Content
