Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Example 1: Reference Figure 1-5The illustrated wear-resistant and easy-to-install automotive fastener includes a pair of fixed rings 2. Both the fixed rings 2 and the rotating ring 1 are made of aluminum alloy to improve wear resistance. The rotating ring 1 is rotatably connected to the outer side of the fixed rings 2, allowing the rotating ring 1 to rotate flexibly relative to the fixed rings 2 for easy subsequent operation and adjustment. Multiple grooves 3 are formed on the inner side of the fixed rings 2, providing space and guidance for the installation and sliding of the fastening components. A fastening component is installed within the grooves 3. The fastening component includes a sliding rod 6 that is slidably connected to the inner wall of the groove 3. The sliding rod 6 can slide smoothly within the groove 3, thereby achieving the fastening of... For fastening components of the same size, a fixing block 4 is fixedly connected to the outer side of the sliding rod 6, and a support block 5 is fixedly connected to one end of the fixing block 4. The support block 5 can make close contact with the fastened component during the fastening process, providing stable support force and preventing the component from loosening. The outer side of the rotating ring 1 has multiple guide grooves 10 that are adapted to the sliding rod 6. The guide grooves 10 cooperate with the sliding rod 6, so that the rotation of the rotating ring 1 can accurately drive the sliding rod 6 to perform the corresponding sliding action, ensuring the accuracy and reliability of the fastening operation. A pair of sliders 11 are fixedly connected to the outer side of the sliding rod 6, and the inner wall of the groove 3 is... A sliding groove 12 adapted to the slider 11 is provided on the surface. The cooperation between the slider 11 and the sliding groove 12 further ensures the smoothness and directionality of the sliding rod 6 sliding within the sliding groove 3, preventing the sliding rod 6 from deviating or shaking, thereby improving the working accuracy and reliability of the fastening assembly. Multiple fixing rods 13 are fixedly connected between a pair of rotating rings 1. The fixing rods 13 enhance the connection strength and stability between the pair of rotating rings 1, making the entire fastener structure more stable during use and less prone to deformation or damage. The same connecting frame 7 is fixedly connected to the outer side of a pair of fixing rings 2. The connecting frame 7 facilitates the fastening... The fasteners facilitate the connection and installation of other automotive components, making the installation process simpler and faster, while also improving the overall installation stability of the fasteners on the vehicle. Bolts 8 are provided on the outer side of the rotating ring 1, and threaded holes 9, compatible with the bolts 8, are provided on the inner sides of both the rotating ring 1 and the fixed ring 2. Through the cooperation of the bolts 8 and the threaded holes 9, the rotating ring 1 and the fixed ring 2 can be further secured together after the tightening operation, preventing the fastener components from loosening due to vibration or other factors during vehicle operation. This ensures the fastening effect of the fasteners is durable and reliable, improving the safety and stability of vehicle operation.

[0024] In this embodiment, a pair of fixed rings 2 are placed on the outside of the automotive parts that need to be fastened, and the rotating ring 1 is dragged to rotate. The pair of rotating rings 1 rotate simultaneously through a pair of fixed rods 13. During the rotation, the rotating ring 1 guides the sliding rod 6 through the guide groove 10. The sliding rod 6 drives the slider 11 to slide along the sliding groove 12. The sliding rod 6 slides along the sliding groove 3. The sliding rod 6 drives the support block 5 to move through the fixed block 4, and abuts against and fixes the outside of the automotive parts. The bolt 8 is connected to the corresponding threaded hole 9 to keep the rotating ring 1 and the corresponding fixed ring 2 stable.

[0025] Example 2: Reference Figure 1-5 Based on the same concept as in Embodiment 1 above, this embodiment also proposes that a limiting ring 14 is fixedly connected to the outer side of the rotating ring 1. The limiting ring 14 and the matching guide rail opened on the outer side of the fixed ring 2 cooperate with each other to accurately limit the rotation of the rotating ring 1, preventing it from deviating or shaking during rotation, ensuring the stability and accuracy of rotation, thereby ensuring the operating accuracy and reliability of the entire device. The outer side of the support block 5 is provided with anti-slip texture. These anti-slip textures can increase the friction between the support block 5 and the contact surface, making it more stable and less prone to slipping during support, thus providing a stable and reliable support foundation for the entire device. At the same time, the outer side of the support block 5 is set with an arc surface. This arc surface design can better fit the surface shape of the supported object.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
