[0025] Reference Figure 2-Figure 3There are five limiting holes 41 in total, and the inner diameters of the five limiting holes 41 are adapted to the outer diameters of the limiting columns 47. By setting the limiting columns 47 to cooperate with the limiting holes 41, the distance between the bolts in different automobile chassis structures can be adjusted to adapt to the spacing. The limiting columns 47 are clamped on the side inner walls of the limiting holes 41, and the outer wall of the telescopic spring 44 on the side away from the movable plate 43 is fixedly connected to the inner wall of one side of the nut body 3. The outer wall of the side of the limiting column 47 is fixedly connected with a wear-resistant pad, and an outer wall on one side of the handle 45 is provided with an indicator mark 46. The operation method is prompted by setting the indicator mark 46, and the end of the fixed bolt body 1 away from the nut body 3 is fixedly connected with the adjusting disk 2.
[0026] Reference Figure 3-Figure 4 The buffer mechanism 5 includes a slide 51, which is provided on the inner wall of one side of the movable plate 43. The inner wall of one side of the slide 51 is slidably connected to a sliding block 52. The outer walls on both sides of the sliding block 52 are respectively fixedly connected to spring dampers 53. By setting the spring damper 53, a certain buffer is provided for the limit column 47 on the sliding block 52, thereby reducing the problem of breakage and deformation of the limit column 47 caused by the violent pulling and collision of the limit hole 41. The end of the spring damper 53 away from the sliding block 52 is fixedly connected to the inner wall of one side of the movable plate 43, and the sliding block 52 is fixedly connected to the inner wall of one side of the limit column 47.

[0027] Working principle: by inserting the fixing bolt body 1 into the hole connecting the automobile chassis and other fixing structures, and then aligning the nut body 3 with one end of the fixing bolt body 1 and rotating it, the nut body 3 and the fixing bolt body 1 are bolted according to the thread fixing spacing between the automobile chassis structure. When the nut body 3 is rotated to a certain position, the limiting column 47 is aligned with the corresponding limiting hole 41 position, so that the telescopic spring 44 pushes the movable plate 43 to move, and the movement of the movable plate 43 drives the limiting column 47 to move, so that the limiting column 47 is clamped inside the limiting hole 41, and the rotation of the fixing bolt body 1 and the nut body 3 is limited to prevent loosening. At the same time, when the fixing bolt body 1 thread and the nut body 3 internal thread are used for a long time and there is deformation and shaking up and down, the fixing bolt body 1 is shaken to move the limiting hole 41, and the limiting hole 41 moves to squeeze the internally clamped limiting column 47, and the limiting column 47 moves to drive the sliding block 52 to move. The sliding block 52 moves to squeeze the spring damper 53 for flexible buffering, thereby reducing the extrusion deformation and breakage of the limiting column 47.
