Then, by rotating the fastening bolt 15 through the thread groove 16, the other end of the fastening bolt 15 can exert force on the connector, resulting in a better lock. Through the above structure, the nut can be effectively prevented from loosening during vehicle operation. Its unique design can maintain a tight state even when the vehicle is subjected to severe vibrations on rough roads, ensuring the normal operation of the suspension system and improving driving safety.

[0025] like Figures 1 to 3 As shown, the internal thread 13 of the first nut 11 is provided with anti-slip grooves 21; the anti-slip grooves 21 are arranged in a circular array on the side wall of the internal thread 13; when an eccentric nut is required during operation, the anti-slip grooves 21 on the internal thread 13 can provide a better locking effect, allowing for better contact between the anti-slip grooves 21 and the connecting parts, preventing slippage; through the above structure, the nut can be effectively prevented from loosening due to the high-frequency vibration of the engine. The grooves will generate resistance to loosening, just like gears interlocking, preventing the bolt from coming out of the nut.

[0026] like Figure 2 and Figure 3As shown, a locking ring plate 31 is attached to the bottom of the first nut 11; the locking ring plate 31 has a through hole inside the first nut 11; the bottom of the locking ring plate 31 has an anti-slip groove 32; the anti-slip groove 32 is arranged in a circular array at the bottom of the locking ring plate 31; when an irregularly shaped nut is needed during operation, the locking ring plate 31 and the anti-slip groove 32 can make a large-area contact with the contact surface of the part, increasing its friction and preventing loosening; through the above structure, it is possible to effectively customize according to the contour of the irregularly shaped flat nut to ensure a tight fit.
