The injection pipes 12 are communicated with the fixed cylinder 11 for easy injection of lubricating oil. A plug block 15 is threadedly connected to one end of the injection pipe 12 away from the fixed cylinder 11 for easy sealing of the injection pipe 12.

[0022] A piston 19 is slidably connected inside a fixed cylinder 11 to facilitate the movement of the piston 19 for extruding lubricating oil. A connecting column 13 is fixedly connected to the side surface of the piston 19, and a pulling block 14 is fixedly connected to one end of the connecting column 13 away from the piston 19 to facilitate pulling the connecting column 13 to move. The output end of the fixed cylinder 11 is fixedly connected with a communicating pipe 16. A check valve is arranged on the communicating pipe 16 to prevent the backflow of lubricating oil.
