[0034] Working principle: In actual use, grease is added to the oil tank 1 through the one-way valve 17. According to actual use, the hand wheel 26 is turned to adjust the length of the extension tube 19 and the grease tube 18 to enable different devices to add grease. After adjustment, the Bluetooth communication module 8 can receive a signal, and the processor 9 sends a signal to the servo motor 13. The servo motor 13 drives the driven gear 20 through the driving gear 14 to realize the rotation of the driven gear 20. The driven gear 20 can realize the up and down movement of the driving rod 12. When the driving rod 12 moves up and down, it drives the piston 2 to squeeze the oil tank 1. The grease in the equipment can be added to the equipment.
