By setting the auxiliary mechanism 5, the wear generated by the friction between the bolt main body 3 and the vehicle suspension main body 1 is reduced. The anti-loosening mechanism 4 includes a fixed disk 41, the fixed disk 41 is fixedly connected to one end of the bolt main body 3, and an external thread 42 is provided on the outer side wall of the bolt main body 3. By setting the external thread 42, it is threadedly fixed and separated from the chuck 43. A chuck 43 is threadedly connected to the outer side wall of the external thread 42. An internal thread 44 is provided on the inner side wall of the bolt main body 3, and a reverse bolt 45 is threadedly connected to the inner side wall of the internal thread 44. By setting the reverse bolt 45, it is reversely threadedly fixed and separated from the internal thread 44 on the bolt main body 3. One end of the reverse bolt 45 is fixedly connected to an adjusting disk 46, a dial 47 is slidably connected to the inner side wall of one side of the adjusting disk 46, and a positioning column 48 is fixedly connected to the outer side wall of one side of the dial 47.

[0025] Referring to Figures 2 - 3 , the chuck 43 is clamped on the outer side wall of one side of the vehicle suspension main body 1. A frosted pad is fixedly connected to the outer side wall of the dial 47. The positioning column 48 penetrates through the inner side wall of one side of the adjusting disk 46 and extends to the outer side wall of the adjusting disk 46. A small spring 49 is fixedly connected to the outer side wall of the dial 47 away from the positioning column 48. By setting the small spring 49, a continuous thrust is generated on the dial 47. One end of the small spring 49 away from the dial 47 is fixedly connected to the inner side wall of one side of the adjusting disk 46. A limiting hole 410 is provided on the outer side wall of the chuck 43. There are four limiting holes 410 in total. The inner diameter of the four limiting holes 410 is adapted to the outer diameter of the positioning column 48. By setting the positioning column 48 to cooperate with the limiting hole 410, the fixed disk 41 and the chuck 43 are clamped and fixed. The positioning column 48 is clamped on the inner side wall of the limiting hole 410. Inner wall panels 2 are fixedly connected to the inner side walls of both sides of the vehicle suspension main body 1.

[0026] Referring to Figures 3 - 4, the auxiliary mechanism 5 includes a grinding groove 51 which is opened on the outer side wall of the fixed disk 41. One side outer wall of the adjusting disk 46 is fixedly connected with a first sponge pad 52, and one side outer wall of the fixed disk 41 is fixedly connected with a second sponge pad 53. Receiving grooves 54 are opened on both outer side walls of the vehicle suspension main body 1. By providing the receiving grooves 54, the convex surfaces of the adjusting disk 46 and the fixed disk 41 are reduced, so that the outer surface of the vehicle suspension main body 1 is almost kept as a whole plane, reducing looseness and wear caused by external friction and collision. There are several grinding grooves 51, and several grinding grooves 51 are respectively opened on the outer side walls of the fixed disk 41 and the adjusting disk 46. The first sponge pad 52 is attached to one side outer wall of the vehicle suspension main body 1. By providing the first sponge pad 52 and the second sponge pad 53 to cooperate with each other, the wear caused by the friction and collision between the parts and the outer surface of the vehicle suspension main body 1 is reduced. The second sponge pad 53 is attached to one side outer wall of the vehicle suspension main body 1. The inner diameter of the receiving groove 54 is adapted to the adjusting disk 46, and the inner diameter of the receiving groove 54 is adapted to the outer diameter of the fixed disk 41.

[0027] Working principle: By rotating the fixed disk 41, the bolt main body 3 rotates. The bolt main body 3 rotates and is threadedly connected with the chuck 43 attached to the other side of the vehicle suspension main body 1, so that the chuck 43 moves closer to each other along the threads on the surface of the bolt main body 3, clamping both sides of the vehicle suspension main body 1. Subsequently, rotate the adjusting disk 46 to make the reverse bolt 45 rotate, so that the reverse bolt 45 is fixedly threaded with the internal thread 44. At the same time, the rotation of the adjusting disk 46 drives the positioning column 48 to move. The positioning column 48 moves to the corresponding position of the limiting hole 410, so that the small spring 49 pushes the dial 47 to move. The movement of the dial 47 pushes the positioning column 48 to move, and the positioning column 48 moves and is clamped and fixed with the limiting hole 410 to prevent the adjusting disk 46 from rotating.
