AI Technical Summary
The outer wall of the existing rivets is smooth, does not deform quickly enough, and the grooves are discontinuous, resulting in not deforming quickly enough.
It is designed with a rivet for riveting, which includes the tube part, the bending tube part, the arc, the ring, the ring, the tightening of the ball and the lever. The bending tube part is a continuous bending structure. The pressure of the sphere is more uniform. The spacing between the inner side of the curved tube part of the tube part provides a space for accommodation.
By improving the rivet structure and designing the deformation position as the bent pipe body, the deformation is easier and hierarchical, the total thickness is thick, and the compression effect is good. The concave deformation part on the inside of the bent tube body provides accommodating space to avoid affecting the outward movement of the tie rod.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Example:
[0025] See also Figure 1-Figure 2 The utility model provides a rivet for riveting, including a tube body part 1, a bent tube body part 2 is integrally connected to the bottom of the tube body part 1, an arc head 3 is integrally connected to the bottom of the bent tube body part 2, a ring plate 4 is integrally connected to the top of the tube body part 1, the position of the arc head 3 fits the installation of a clamping ball 5, a pull rod 6 is fixedly connected to the clamping ball 5, and an external thread 7 is provided on the outer side of the pull rod 6 located on the ring plate 4.
[0026] Specifically, Figure 1 and Figure 2 As shown, the bent tube body portion 2 is a continuous bending structure, which is easier to deform, has multiple levels, a thick thickness, and good stability.
[0027] Specifically, Figure 1 As shown, there is a gap between the inner walls of the tube body part 1 and the bent tube body part 2 and the pull rod 6, and the inner concave deformation part of the bent tube body part 2 also has space to accommodate it, which will not affect the outward movement of the pull rod 6.
[0028] Specifically, Figure 1 As shown, an arc-shaped inwardly convex clamping body is provided at the connection position between the bent tube part 2 and the arc head 3, and the inwardly convex clamping body is arranged to cover the pressing ball 5, limiting the upward movement of the pressing ball 5.
[0029] Specifically, the outer walls of the tube body portion 1, the bent tube body portion 2 and the arc head 3 are arranged flush, so that perforation is convenient.
[0030] Specifically, Figure 1 As shown, the inner ring of the ring plate 4 is arranged in contact with the pull rod 6 to play a guiding role.
[0031] Working principle:
[0032] Insert the external thread 7 into the handheld device, and when the handheld device works, the pull rod 6 moves outward, and the compression ball 5 presses the bent tube part 2 to deform. Since the bent tube part 2 is a corrugated continuous bending structure, its concave bending part reduces the deformation resistance, and the bent tube part 2 can be flattened quickly, with many flattening levels and a thick total thickness, and is firmly fixed. There is also space to accommodate the concave deformation part inside the bent tube part 2, which will not affect the outward movement of the pull rod 6.
[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
