[0025] The working assembly includes a fixed slot block 2 and a hydraulic rod 3. One end of the stud 1 is fixedly connected to the fixed slot block 2, and the hydraulic rod 3 is arranged inside the fixed slot block 2.

[0026] The fixing assembly includes a locking rod 4, a fixed shaft 5, a disc 6, a fixed column 7, a compression spring 8, a first fixed slot column 9, a second fixed slot column 10, a locking ring 11 and a third fixed slot column 12. The locking rod 4 is arranged inside the fixed slot block 2, and the fixed shaft 5 passes through the inner wall of the locking rod 4; one end of the hydraulic rod 3 is fixedly connected to the disc 6, one end of the disc 6 is fixedly connected to the fixed column 7, the outer wall of the fixed column 7 is slidably connected to the compression spring 8, one end of the disc 6 is fixedly connected to the first fixed slot column 9, one end of the fixed slot block 2 is fixedly connected to the second fixed slot column 10, the outer wall of the stud 1 is rotatably connected to the locking ring 11, and the end of the stud 1 away from the fixed slot block 2 is fixedly connected to the third fixed slot column 12.

[0027] Among them, Figure 3 As shown, the locking rod 4 forms a rotating structure with the fixed slot block 2 through the fixed shaft 5, which is beneficial for the wheel hub to be engaged and fixed by opening the locking rod 4 when the stud 1 is fixed on the wheel hub.

[0028] Among them, Figure 3As shown, the fixed column 7 forms a sliding structure with the second fixed slot column 10 through the locking rod 4 and the disc 6, which is beneficial for pressing the locking rod 4 into the groove of the fixed slot block 2 when the bolt needs to be installed. Then the rotation of the locking rod 4 will drive the disc 6 to slide and drive the fixed column 7 to slide inside the second fixed slot column 10. At this time, the compression spring 8 is performing a compression operation, and then the stud 1 is rotated for installation.

[0029] Among them, Figure 2 As shown, two groups of locking rods 4 are provided, and the position relationship of the two groups of locking rods 4 is symmetrical about the midpoint of the disk 6. The design of the two groups of locking rods 4 is conducive to more stable clamping and fixing operation on one side of the wheel hub.

[0030] Example 2

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, this embodiment further illustrates Example 1, one end of the third fixed slot column 12 is fixedly connected to a fixed block 13, an oil outlet hole 14 is provided inside the stud 1, a cover 15 is provided outside the fixed block 13, a protruding block 16 is provided on the inner wall of the cover 15, a sealing ring 17 is provided on the inner wall of the cover 15, a handle 18 is fixedly connected to the outer wall of the cover 15, and an oil inlet hole 19 is provided outside the third fixed slot column 12.

[0032] Among them, Figure 4 As shown, the cover 15 forms a snap-fit ​​structure with the fixed block 13 through the protruding block 16, which is conducive to injecting lubricating oil through the oil inlet hole 19. Then, the cover 15 is rotated by turning the handle 18, so that the protruding block 16 and the groove of the fixed block 13 are snap-fitted and fixed, so that the cover 15 is fixed on the fixed block 13 and the oil inlet hole 19 is sealed.

[0033] Among them, Figure 1 As shown, eight groups of oil outlet holes 14 are provided, and the positional relationship of the eight groups of oil outlet holes 14 is equidistantly distributed about the central axis of the stud 1, which is conducive to the lubricating oil entering the oil outlet holes 14 arranged inside the stud 1 through the channel of the oil inlet hole 19, and lubricating the stud 1 through the oil outlet holes 14, so that the bolt can be refueled without being disassembled.

[0034] When in use: First, when the bolt needs to be installed, the locking rod 4 can be pressed and placed in the groove of the fixed slot block 2, and then the rotation of the locking rod 4 will drive the disc 6 to slide and drive the fixing column 7 to slide inside the second fixed slot column 10. At this time, the compression spring 8 is in a compressed state, and then the wheel hub is fixed for the first time by rotating the stud 1. When the locking rod 4 passes through the inside of the wheel hub and comes out, it will automatically spring open to a certain angle under the action of the compression spring 8, and play a clamping and fixing operation on one side of the wheel hub. Then rotate the locking ring 11 to make the locking ring 11 clamp and fix the other side of the wheel hub. The three fixing operations enable the bolt to stably connect the automobile wheel hub and the steel rim, and it will not loosen easily, thereby achieving effective fixing of the bolt.

[0035] Finally, lubricating oil is added to the stud 1. The lubricating oil can enter the oil outlet hole 14 set inside the stud 1 through the channel of the oil inlet hole 19, and lubricating the stud 1 through the oil outlet hole 14, so that the stud 1 can be lubricated without being disassembled. Then, the cover 15 is rotated by turning the handle 18, so that the raised block 16 is engaged and fixed with the groove of the fixed block 13, so that the cover 15 is fixed on the fixed block 13 to prevent other external impurities from entering the oil filling channel and affecting the lubricating effect of the lubricating oil. The setting of the sealing ring 17 effectively prevents the lubricating oil from leaking out from the gap of the cover 15, so that the cover 15 has a more stable sealing performance.
