The connecting pipe 401 is provided through the upper end of the front surface of the baffle 3 at the front end. The front end of the connecting pipe 401 is clamped and installed with a guide cylinder 402. The guide groove 410 is provided through the lower end of the inner part of the outer ring 101. A clamping block 412 is installed on the front side of the lower end of the inner part of the bearing seat 2. The clamping block 412 is connected to the guide groove 410. The guide cylinder 402 is close to the connecting pipe 401. A No. 1 fitting block 403 is installed on one side, and a No. 2 fitting block 404 is installed on the side of the connecting tube 401 close to the guide tube 402. The No. 1 fitting block 403 fits with the No. 2 fitting block 404. A rotating cover 405 is installed on the outer side of the guide tube 402. The No. 1 fitting block 403 and the No. 2 fitting block 404 are movably installed inside the rotating cover 405. The inner wall of the rotating cover 405 and the outer side of the No. 2 fitting block 404 are respectively provided with threads, and the rotating cover 405 is connected to the No. 2 fitting block 404 through the threads. The second fitting block 404 is snap-fitted and connected, a hose 407 is installed on the side of the guide cylinder 402 away from the connecting pipe 401, the upper end of the hose 407 is installed on the upper end of the inner upper end of the bearing seat 2, an injection pipe 408 is installed on the upper end of the hose 407, and a No. 1 sealing cap 409 is installed on the upper end of the injection pipe 408 through a thread, a sealing ring 406 is snap-fitted and installed between the No. 1 fitting block 403 and the No. 2 fitting block 404, and a snap-fit ​​groove 406 is installed on the lower end of the inner lower end of the guide groove 410. 11. The rear end of the locking block 412 is locked and installed in the inside of the locking groove 411. A connecting groove 413 is provided between the locking block 412 and the bearing seat 2.

[0031] When in use, first install the bearing body 1 by pressing it, so that the bearing body 1 is installed to the inside of the bearing seat 2, and then as the bearing body 1 moves, the locking block 412 drives the sealing block 414 to lock into the inside of the locking groove 411, and then after the locking block 412 is locked, the bearing body 1 can be installed. Then the user first puts the sealing ring 406 between the No. 1 locking block 403 and the No. 2 locking block 404, and then fits the No. 1 locking block 403 and the No. 2 locking block 404. After fitting, the user rotates the rotating cover 405 to connect the rotating cover 405 with the No. 2 locking block 404 through the thread, so that the No. 1 locking block 403 and the No. 2 locking block 404 are stably connected to avoid falling off, thereby completing the installation of the bearing body 1, and then the user puts the bearing body 1 through the bearing seat 2 The body 1 is installed to the interior of the engine. Then, when the engine needs to replace the lubricating oil inside the bearing body 1 after long-term use, the user can open the end cover of the engine, and then remove the No. 1 sealing cap 409 and the No. 2 sealing cap 416 through the threads respectively. Then, the old lubricating oil inside the bearing body 1 can be discharged along the guide groove 410, the connecting groove 413 and the drain pipe 415. Then, the user injects new lubricating oil into the interior of the hose 407 through the injection pipe 408, and then the lubricating oil entering the hose 407 enters the interior of the bearing body 1 along the guide cylinder 402 and the connecting pipe 401, realizing rapid replacement of the lubricating oil and improving the overall processing efficiency. Then, after the lubricating oil replacement is completed, the No. 1 sealing cap 409 and the No. 2 sealing cap 416 can be installed again through the threads to seal the injection pipe 408 and the drain pipe 415.
