In addition, the self-riveting structure design of the existing self-riveting studs is relatively simple, and the stability of the self-riveting needs to be improved. Therefore, a self-riveting stud with adjustable spacing is needed to solve the above problems. Utility Model Content

Riveting grooves 11 are provided on both sides of the upper end of the upper plate 1. The cross-sectional shape of the rivet cover 3 is an equilateral hexagon, and the size of the rivet groove 11 is smaller than that of the rivet cover 3. The hexagonal rivet cover 3 has good structural strength and is convenient for riveting. A connecting column 31 is welded on the lower end of the rivet cover 3, and a connecting groove 12 is provided on the lower inner wall of the rivet groove 11 to cooperate with the connecting column 31. A stud 32 is welded on the lower end of the connecting column 31, and the rivet cover 3 is connected to the stud 32 through the connecting column 31 to form a rivet column structure. The rivet column structure can connect the upper plate 1 and the lower plate 2. The upper plate 1 and the lower plate 2 can be thin plate materials in different industries. Specifically, the connecting column 31 is inserted into the connecting groove 12, and then the rivet cover 3 is covered in the rivet groove 11 for riveting.
