[0023] Reference Figures 1 to 3 A riveting die head includes a male head 10 and a female head 20. The male head 10 includes a riveting seat 11 and a supporting seat 12. The female head 20 is provided with a riveting groove 21. The riveting seat 11 can be arranged opposite to the riveting groove 21 when the male head 10 and the female head 20 are installed on the rivet gun body. It also includes an elastic connecting sleeve 30.

[0024] A first connecting portion 41 and a second connecting portion 42 are respectively provided on two opposite sides of the riveting seat 11 and the supporting seat 12;

[0025] The elastic connecting sleeve 30 is arranged between the riveting seat 11 and the supporting seat 12 and a connecting groove 31 is arranged on its inner wall. The first connecting part 41 is connected to one side of the connecting groove 31, and the second connecting part 42 is connected to the other side of the connecting groove 31 and has a distance between it and the first connecting part 41.

[0026] In the present utility model, when used, refer to Figure 1 , install the riveting die head on the gun body of the rivet gun, and drive the male head 10 to approach the female head 20 through the gun body of the rivet gun. Specifically, place the workpiece to be riveted between the female head 20 and the male head 10. After placing the rivet on the male head 10, start the gun body of the rivet gun to drive the male head 10 to move toward the female head 20, so that the male head 10 drives the rivet to abut against the rivet groove 21 on the female head 20, thereby causing the rivet to deform under force, and the workpiece to be riveted together; specifically, the support seat 12 abuts against the outer ring of the upper end surface of the female head 20, so that the support seat 12 is forced to move toward the direction of the riveting part 50 and compress the elastic connecting sleeve 30, and the support seat 12 is used to limit the rivet, that is, a through groove 60 is provided on the support seat 12, and the riveting part 50 is penetrated in the through groove 60, and the lower end surface of the riveting part 50 is higher than the lower end surface of the support seat 12, so that the rivet is adsorbed on the magnetic part When the rivet is on the male head 10, at least part of it is located in the through groove 60, so that no matter in what posture the rivet is connected to the male head 10, it will be confined in the through groove 60, thereby being opposite to the rivet groove 21 on the female head 20, avoiding the situation of rivet misalignment; when riveting is completed, the gun body of the rivet gun drives the male head 10 to reset in the opposite direction, and the support seat 12 is reset under the action of the elastic connecting sleeve 30; further, the elastic connecting sleeve 30 can also play an energy absorption role during riveting, so that the excessive pressure generated during the riveting stamping process is transmitted to the elastic connecting sleeve 30 and absorbed, reducing the impact on the gun body of the rivet gun; the advantage of the utility model is that: through the above-mentioned structure, the firmness of the connection between the riveting seat 11 and the support seat 12 can be improved, and the support seat 12 can be avoided from being separated from the riveting seat 11 during the riveting process, while also meeting the movement requirements during riveting, and having very good practicality.

[0027] Preferably, a riveting portion 50 is provided on the riveting seat 11, and a through groove 60 penetrating along the riveting direction is provided on the support seat 12, and the riveting portion 50 is penetrated in the through groove 60; this arrangement can provide space for avoiding the elastic connecting sleeve 30 and the support seat 12, and at the same time does not affect the riveting effect.

[0028] Preferably, a mounting groove 51 is provided on the riveting portion 50, and a magnetic member 70 for adsorbing the rivet is provided in the mounting groove 51; by providing the magnetic member 70, the rivet and the male head 10 can be connected together, which not only eliminates the need for the user to hold the rivet with his hands, but also makes the rivet better aligned, thereby improving the riveting effect.

[0029] A first threaded connection column 81 is provided on the male head 10, and a second threaded connection column 82 is provided on the female head 20; the first threaded connection column 81 and the second threaded connection column 22 enable the male head 10 and the female head 20 to be respectively installed on opposite sides of the gun body of the rivet gun.

[0030] The male head 10 is provided with a first limiting portion 91 , and the female head 20 is provided with a second limiting portion 92 ; this arrangement can be used to limit the rotation of the male head 10 and the female head 20 on the gun body of the rivet gun.

[0031] A first rubber ring 93 is sleeved on the outer wall of the male head 10, and a second rubber ring 94 is sleeved on the outer wall of the female head 20; the first rubber ring 93 and the second rubber ring 94 can cooperate with the gun body of the rivet gun to limit the reverse retreat during the riveting and stamping process to prevent loosening.

[0032] A rivet gun comprises the riveting die head.

[0033] Of course, the present invention is not limited to the above-mentioned embodiments, and technicians familiar with the field may make equivalent modifications or substitutions without violating the spirit of the present invention.
