[0027] The utility model can further improve the fixing ability between the rivet stud body 1 and the rivet nut body 3 by providing the anti-loosening mechanism 4, so that the rivet nut body 3 is originally connected to the rivet stud body 1 vertically through a thread, and after the anti-loosening mechanism 4 is added, a connection in the vertical and horizontal directions is formed, so that a cross is formed between the rivet nut body 3 and the rivet stud body 1, and the connection is more stable, preventing the rivet stud body 1 and the rivet nut body 3 from loosening due to external vibration during use, causing an unstable connection between the two and falling.

[0028] Example 2

[0029] In one embodiment, the threaded hole 2 is provided with an embedding groove 6 around it, and the insertion rod 407 is embedded into the inner side of the embedding groove 6. The size of the insertion rod 407 is consistent with the size of the embedding groove 6, and the embedding groove 6 and the insertion rod 407 are both circular.

[0030] The utility model provides a plurality of engaging grooves 6, into which a plurality of insert rods 407 can be inserted, thereby further improving the fixing ability between the rivet stud body 1 and the rivet nut body 3. By setting the sizes of the engaging grooves 6 and the insert rods 407 to be consistent, loosening of the engaging grooves 6 and the insert rods 407 during engagement can be avoided.

[0031] Example 3

[0032] In one embodiment, sliding grooves 7 are opened all around the bottom of the threaded hole 2, and the sliding block 406 is slidably connected to the inner side of the sliding groove 7, a rotating groove 8 is opened on the top of the rotating block 401, and the rotating groove 8 is cross-shaped, and a buffer pad 9 is fixedly connected to the top of the deformation part 5, and the material of the buffer pad 9 is rubber.

The moving block 401 drives the rotating rod 402 to rotate, the rotating rod 402 drives the rotating disk 403 to rotate, the rotating disk 403 drives the swing rod 404 to swing, the swing rod 404 drives the moving block 405 to move around at the same time, and the sliding block 406 slides on the inner side of the sliding groove 7. At this time, the movement of the moving block 405 drives the insertion rod 407 to move outward at the same time until the insertion rod 407 is embedded in the inner side of the embedding groove 6 to form a horizontal connection. At this time, a cross connection is formed between the rivet stud body 1 and the rivet nut body 3, which is more stable and not easy to loosen.
