[0042] During the sliding movement of the mobile tube 9, the tension spring 24 between the fixed tube 8 and the mobile tube 9 is compressed, and during the compression, the abutting rod 23 at the abutting plate 22 on the mobile tube 9 is constantly abutting against the elastic sheet 20 on the fixed tube 8, so as to push the elastic sheet 20 away, and when the mobile tube 9 is loosened, the elastic potential energy of the tension spring 24 makes the fixed rod 17 clamped at the fixed hole 19, so that the mobile tube 9 and the fixed tube 8 are in the flow-through state, so that the lubricating oil is introduced from one end of the mobile tube 9, passes through the oil leakage hole 25 on the fixed sleeve 21, enters the drainage tube 7 along the fixed tube 8, and finally enters the driving gear 5.
