A plurality of mounting through holes 3 are opened on the main body 1, and solid lubricants are arranged in the plurality of mounting through holes 3. The solid lubricant is made of graphite or graphene, and the self-lubricating properties of the main body 1 can be maintained through the solid lubricant. A circular opening 2 is opened in the middle of the main body 1. When the main body 1 is installed on the equipment, the driving shaft of the equipment will be located in the circular opening 2.

[0024] Reference Figure 2-4 , oil storage tanks are arranged on both sides of the main body 1, and oil outlet mechanisms are arranged on the other sides of the two oil storage tanks. Circular holes are opened on both sides of the circular mouth 2, and the two circular holes are respectively connected with the two oil storage tanks. The oil storage tanks are used to store the butter for lubricating the drive shaft and the inner wall of the circular mouth 2. The lubricating butter 8 in the two oil storage tanks can be squeezed into the two circular holes through the operation of the two oil outlet mechanisms, and then the lubricating butter 8 is transported to the circular mouth 2 through the two circular holes, so that the inner wall of the circular mouth 2 and the drive shaft of the equipment have good lubricity, avoiding friction damage between the drive shaft and the inner wall of the circular mouth 2 during long-term rotation, which can effectively improve the main body. 1, and at the same time can increase the convenience of the main body 1 after installation, two oil outlet mechanisms are provided with circular rubber blocks 7, the two circular rubber blocks 7 are respectively arranged in the middle of the two oil storage tanks, and lubricating butter 8 is provided in the two oil storage tanks, and the two lubricating butters 8 are respectively abutted against the opposite sides of the two circular rubber blocks 7. The operation of the two oil outlet mechanisms can slowly push the two circular rubber blocks 7 to move toward each other, and the two circular rubber blocks 7 moving toward each other will squeeze the two lubricating butters 8, and the two lubricating butters can be slowly squeezed into the round mouth 2, and the lubricating butter 8 mainly plays a role in increasing the lubricity of the drive shaft and the inner wall of the round mouth 2.

[0025] Reference Figure 2-4The two oil outlet mechanisms include two buffer springs 6 fixedly connected to the other side of the two oil storage tanks, respectively. The opposite ends of the two buffer springs 6 are fixedly connected to the other side of the two circular rubber blocks 7. The buffer spring 6 is a component with a slowly restoring elastic force. The elastic force of the two buffer springs 6 can slowly push the two circular rubber blocks 7 to move toward each other. The two circular rubber blocks 7 will slowly squeeze the two lubricating butters 8, and squeeze the two lubricating butters 8 into the circular mouth 2 through the two circular holes, so that the inner wall of the circular mouth 2 and the driving shaft are filled with lubricating butter 8, which can increase the lubrication effect between the inner wall of the circular mouth 2 and the driving shaft.

Inserting the round plugs 11 into the circular holes will block the circular holes, so as to prevent the lubricating grease 8 from entering the circular opening 2 when the main body 1 is not installed. Grooves 14 are provided at the upper and lower ends of the two circular holes. A telescopic rod 15 is fixed in each of the four grooves 14, and a card block 17 is fixed at one end of each of the four telescopic rods 15. The groove 14 is used to store the telescopic rod 15. The telescopic rod 15 is a telescopic rod. The card block 17 can be kept vertically lifted and lowered during movement through the telescopic rod 15. Springs 16 are sleeved on each of the four telescopic rods 15. The opposite ends of the four springs 16 are respectively fixedly connected to the four card blocks 17. The other ends of the four springs 16 are respectively fixedly connected to the four grooves 14. The upper and lower ends of the two round plugs 11 are provided with card slots. The four card blocks 17 are respectively The buckles are in the corresponding four slots, and the springs 16 have elastic force.

In the process of inserting the two round plugs 11 into the two round holes, when the four slots at the upper and lower ends of the two round plugs 11 move to the positions corresponding to the four card blocks 17, the elastic force of the four springs 16 will push the four card blocks 17, so that the four card blocks 17 are buckled in the four slots respectively. By buckling the four card blocks 17 in the four slots, it can be prevented that the round plugs 11 fall out of the round holes when they are not subjected to a large pulling force, which effectively ensures that the round plugs 11 are inserted into the round holes.
