At the same time, the staff can connect different numbers of oil supply hoses 7 according to the oil supply demand of the engine oil seal to meet the oil supply demand and avoid excessive oil supply and lubricating oil overflow when performing a small amount of work. After connecting the installation cap 6, the transmission shaft 9 can be pushed down inside the cross frame 8 through the cross plate inside the installation cap 6, and the first spring 10 outside the transmission shaft 9 is compressed and deformed to push the transmission shaft 9 to push the sealing chassis 11 at the bottom away from the inside of the embedded block 4, open the oil supply channel of the threaded tube 5, and the lubricating oil is guided into the connecting tube 12 of the oil supply base 2 through the oil supply hose 7 to maintain the oil supply pressure and perform a stable oil filling operation. After removing the installation cap 6, the first spring 10 pushes the transmission shaft 9 to open from the inside of the cross frame 8, driving the sealing chassis 11 to close to the bottom of the threaded tube 5, closing the threaded tube 5, and stopping the oil supply:

[0035] After the oil supply is completed, the staff can insert a screwdriver into the screw cap 14, rotate the adjusting column 13, and screw it into the inside of the connecting pipe 12. The connecting pipe 12 is sealed by the sealing ring 15 in cooperation with the fixing plate 18 and the baffle 19 inside the fixing head 17, thereby strengthening the sealing of the oil supply pipe 3. When the oil supply hose 7 is not disassembled, the sealing state is maintained to avoid oil leakage.
