A limiting plate 104 is rotatably installed on the outer wall of the fixed column 103. Two limiting rings 105 are fixedly connected to the outer wall of the fixed column 103. The inner sides of the two limiting rings 105 are in contact with the front and rear ends of the limiting plate 104. When fixing, after tightening the nut 4, the first fixing block 101 is pulled, causing the first spring 108 to deform. Then, the limiting plate 104 is rotated to move to the lower end of the limiting hole 206. Then, the limiting plate 104 is inserted into the limiting hole 206, and the first fixing block 101 is released. The first spring 108 contracts and drives the limiting plate 104 to be fixed in the limiting hole 206. This solves the problem that vibration during vehicle operation may cause the nut 4 to loosen and fall off, causing the fastener to lose its fixing function and affecting the connection stability.

[0022] Please see Figure 3 In this embodiment, the fixing assembly further includes a first groove 106, a telescopic rod 107, and a first spring 108. The first groove 106 is provided at the center of the lower end of the stud 1. The telescopic rod 107 is fixedly connected to the top of the inner wall of the first groove 106. The other end of the telescopic rod 107 is fixedly connected to the upper end of the first fixing block 101. The first spring 108 is fixedly connected to the top of the inner wall of the first groove 106. The other end of the first spring 108 is fixedly connected to the upper end of the first fixing block 101. The first spring 108 is located outside the telescopic rod 107. By providing a limit ring 105, the limit plate 104 can be prevented from moving laterally on the outer wall of the fixing post 103. By providing the telescopic rod 107, the position of the first fixing block 101 can be kept from shifting during the pulling of the first fixing block 101.

[0023] Please see Figure 4In this embodiment, the anti-loosening component includes a second groove 201, an anti-slip washer 202, a second screw hole 203, a fixing screw 204, a first screw hole 205, and a limiting hole 206; the upper end of the nut 4 has a through first screw hole 205, which is adapted to the stud 1; the upper end of the nut 4 has a second groove 201, the diameter of which is larger than that of the first screw hole 205; the inner wall of the second groove 201 is provided with an anti-slip washer 202. The upper end face of ring 202 is higher than the upper end face of nut 4. The top surface of nut 4 is a regular hexagon. The outer wall of nut 4 has a second screw hole 203 through each of the six sides. The inner wall of the second screw hole 203 is threaded with a fixing screw 204. The lower end of nut 4 has a limit hole 206, which is adapted to the limit plate 104. By setting the fixing screw 204 on the outer wall of nut 4, multiple lateral pressures can be applied to nut 4 after it is fixed, reducing the possibility of nut 4 loosening.

[0024] Please see Figure 5 and Figure 6 In this embodiment, the damping assembly includes a damping shell 301, a buckle 302, a through hole 303, a damper 304, and a second spring 305. The damping shell 301 is slidably disposed on the outer wall of the stud 1. A buckle 302 is fixedly connected to the upper edge of the damping shell 301. A through hole 303 is provided through the upper end of the damping shell 301, and the through hole 303 is adapted to the stud 1. A damper 304 is fixedly connected to the upper and lower ends of the inner wall of the damping shell 301. There is a second spring 305, which is located outside the damper 304. The upper end of the screw head 2 has a hexagonal groove 5, and the upper end of the fixing ring 3 has a third groove 6. The lower end face of the buckle 302 fits against the upper end face of the fixing ring 3. By using the second spring 305 and the damper 304 together, the shock absorption effect can be improved. The second spring 305 provides the restoring force, while the damper 304 reduces the vibration amplitude by dissipating energy and avoids excessive vibration rebound.

[0025] In use, first tighten the nut 4, then pull the first fixing block 101 to deform the first spring 108. Then rotate the limiting plate 104 to move the limiting plate 104 to the lower end of the limiting hole 206. Then insert the limiting plate 104 into the limiting hole 206 and release the first fixing block 101. The first spring 108 retracts and drives the limiting plate 104 to be fixed in the limiting hole 206. This solves the problem that vibrations during vehicle operation may cause the nut 4 to loosen and fall off, causing the fastener to lose its fixing function and affecting the connection stability.

[0026] After the nut 4 is fixed, tighten the fixing screw 204 on the outer wall of the nut 4. This can apply multiple lateral pressures to the nut 4 after it is fixed, reducing the possibility of the nut 4 loosening. During vibration, the second spring 305 and the damper 304 work together to improve the vibration reduction effect. The second spring 305 provides the restoring force, while the damper 304 reduces the vibration amplitude by dissipating energy.

[0027] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
