[0054] 1. The lifting motor 7-1 drives the push block 5 to move upward and the airbag 8-3 to inflate and pressurize, so as to achieve uniform injection of grease and avoid the problem of uneven distribution of grease in the metal universal connecting pipe 4.

[0055] 2. The design of the upper push plate 9 moving down and leveling the grease in a timely manner effectively prevents the grease from being missing at the connection between the bottom of the square tank 1 and the metal universal connecting pipe 4, ensuring continuous filling.

[0056] 3. Use the lower push plate 9 to press down when the push block 5 is close to the bottom to push the residual grease toward the metal universal connecting pipe 4, which significantly reduces the residual grease in the square tank 1 and the pipe.

[0057] 4. The design of the cover 2, the insertion rod 8-5, the limit hook 8-4 and the groove 1-1, as well as the linkage control of the air pump 8-1 and the air bag 8-3, improve the convenience and automation of the mechanism operation.
