A limiting strip 14 is provided on the other side of the mounting ring 11. A limiting groove 24 is provided on the inner side of the annular part 3. The limiting groove 24 is slidingly connected to the limiting strip 14, that is, the limiting groove 24 is limited by the limiting strip 14, so that the annular part 3 maintains sliding motion, and the sliding distance of the annular part 3 is limited by the mounting ring 11. Arc grooves 31 are provided on both sides of the annular part 3, and an arc plate 32 is slidingly provided inside the arc groove 31. The arc plate 32 and the arc groove 31 are a mounting structure. The arc plate 32 is stuck in the arc groove 31 and slides in an arc shape.

[0025] A hexagonal groove 33 is provided inside the arc plate 32, and a fixing component is provided inside the hexagonal groove 33. The fixing component is used to fix the oil pump interface end 2. The fixing component includes a spring 34, and a hexagonal block 35 is provided on one side of the spring 34. The hexagonal block 35 is slidably connected to the hexagonal groove 33. An insert 4 is provided on one side of the hexagonal block 35. Sockets 22 are provided on both sides of the outer side of the mounting ring 11 and the outer side of the threaded groove 21. The insert 4 is disassembled and assembled in the socket 22. A threaded groove 33 is provided on the outer side of the hexagonal groove Mouth 41, a pull rod 42 is movably provided inside the screw mouth 41, the pull rod 42 is pulled and rotated in the screw mouth 41, a connecting bolt 43 is provided on one side of the pull rod 42, a connecting mouth 44 is movably provided on the inner side of the hexagonal block 35, the connecting bolt 43 is movably connected to the connecting mouth 44, the connecting bolt 43 is stuck in the connecting mouth 44 and rotates, so that the pull rod 42 is connected to the hexagonal block 35 and rotates, a bolt 45 is provided on the pull rod 42, and the bolt 45 is threadedly connected to the screw mouth 41.

[0026] By pulling the pull rod 42 from the outside, the plug block 4 is inserted into the hexagonal groove 33, and the bolt 45 is screwed into the screw hole 41 to fix the plug block 4. When the oil pump interface end 2 is installed, the sockets 22 on both sides of the threaded groove 21 are located inside the arc groove 31. The arc plate 32 slides on the arc groove 31, so that the plug block 4 docks with the socket 22. By loosening the bolt 45 and pushing the hexagonal block 35 and the plug block 4 through the spring 34, the plug block 4 is inserted into the socket 22, that is, the oil pump interface end 2 is fixed. , so that it cannot rotate. Since the oil pump interface end 2 will move outward when it rotates, the mounting ring 11 restricts the limit groove 24, so that the annular member 3 cannot move to the side of the oil pump interface end 2, so that the oil pump interface end 2 cannot rotate because the arc plate 32 slides on the arc groove 31, which can avoid the loosening of the thread at the connection between the oil pump connector and the oil pump interface, ensuring the sealing effect. When disassembling the oil pump interface end 2, the plug block 4 can be inserted into the sockets 22 on both sides of the outside of the mounting ring 11 for easy disassembly and assembly.

[0027] The working principle of the present invention is as follows: the threaded strip 12 is connected through the threaded groove 21, so that the oil pump joint end 1 and the oil pump interface end 2 are connected to each other, and when the oil pump joint end 1 and the oil pump interface end 2 are connected to each other, the sealing rubber ring 13 is attached to the sealing groove 23, so that the connection achieves a good sealing effect, and the plug 4 is inserted into the hexagonal groove 33 by pulling the pull rod 42 on the outside, and the bolt 45 is screwed into the screw hole 41 to fix the plug 4. When the oil pump interface end 2 is installed, the sockets 22 on both sides of the threaded groove 21 are located on the inner side of the arc groove 31, and the arc plate 32 is used to seal the arc groove. 31, thereby making the insert block 4 dock with the socket 22, by loosening the bolt 45, and pushing the hexagonal block 35 and the insert block 4 through the spring 34, so that the insert block 4 is inserted into the socket 22, that is, the oil pump interface end 2 is fixed and cannot rotate. Since the oil pump interface end 2 moves outward when rotating, the mounting ring 11 restricts the limiting groove 24 at this time, so that the annular member 3 cannot move toward the side of the oil pump interface end 2, so that the oil pump interface end 2 cannot rotate due to the sliding of the arc plate 32 on the arc groove 31, thereby preventing the thread at the connection between the oil pump connector and the oil pump interface from loosening, thereby ensuring the sealing effect.
