When the lubricating oil is used up, it is taken out and transported through the oil filling port 304.
[0022] Furthermore, the mounting mechanism 5 includes a stopper 501, a semicircular snap ring 502, a limiting groove 503, a receiving groove 504, a rotating column 505 and a sealing ring 506. The outer surface of the coupling 1 is fixedly connected with the stopper 501, and a semicircular snap ring 502 is installed on one side surface of the coupling 1.

The sealing ring 506 is installed on one side surface of the stopper 501. 502, the limiting groove 503, the receiving groove 504, the rotating column 505 and the sealing ring 506 are arranged. When the oil storage box 403 needs to be installed, the sealing ring 506 is taken out from between the blocks 501 on the outside of the coupling 1, and then the semicircular retaining ring 502 on one side is rotated through the rotating column 505 in the receiving groove 504, and then the fixing ring 404 on the outside of the oil storage box 403 is inserted into the limiting groove 503 on the inside of the semicircular retaining ring 502, so as to adjust the position of the oil storage box 403.

[0027] Furthermore, the semicircular retaining ring 502 and the rotating column 505 form a rotating structure, and the sealing ring 506 is installed between the stoppers 501. The setting of the sealing ring 506 can prevent the lubricating oil from leaking out.
[0028] Working principle: First, after the installation of the oil storage box 403 is completed, the lubricating oil in the oil storage box 403 flows out through the oil outlet 405, and the outflowing oil will be absorbed by the sponge pad 402, thereby lubricating the connector 3 on the inner side of the placement groove 401. When the lubricating oil is used up, it is taken out and oil is delivered through the oil filling port 304. When the oil storage box 403 needs to be installed, the sealing ring 506 is taken out from between the blocks 501 on the outside of the coupling 1, and then the semicircular retaining ring 502 on one side is rotated through the rotating column 505 in the receiving groove 504, and then the fixing ring 404 on the outside of the oil storage box 403 is inserted into the limiting groove 503 on the inner side of the semicircular retaining ring 502, so as to adjust the position of the oil storage box 403.
