[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 3 A novel riveting structure includes a toothed disc 4 and a signal push rod 2 arranged on the toothed disc 4, a rivet 1 is arranged on the signal push rod 2, and a rivet hole through which the rivet 1 passes is arranged on the toothed disc 4.

[0022] Among them, the toothed disc 4, the signal push rod 2, the rivet 1 and the rivet hole are all existing technologies. In order to facilitate the rapid positioning of the signal push rod 2 and the toothed disc 4, preferably, the outer wall of the signal push rod 2 is provided with a positioning protrusion, and the outer wall of the toothed disc 4 is provided with a positioning groove corresponding to the positioning protrusion. Through the cooperation of the positioning protrusion and the positioning groove, the pre-positioning between the toothed disc 4 and the signal push rod 2 is guaranteed, thereby facilitating the installation of the rivet 1.

[0023] Reference Figure 2 The improvement of the utility model compared with the prior art is that a rivet slot 5 is provided at one end of the rivet hole, and the inner diameter of the rivet slot 5 is larger than the inner diameter of the rivet hole.

[0024] Reference Figure 2 and Figure 3, a riveted end face 6 is provided at one end of the rivet 1, and a riveted slot hole 5 having an inner diameter larger than that of the rivet hole is provided, and the riveted end face 6 is riveted by a rivet rod of an existing device, and after riveting, a riveted flange 3 is formed on the riveted end face 6 in the riveted slot hole 5, so that the signal push rod 2 is fixed to the toothed disc 4 through the rivet 1. Compared with the prior art, the riveted end face 6 forms a riveted flange 3 embedded in the riveted slot hole 5, rather than protruding from the toothed disc 4, which provides a basis for reducing the volume of the gripping mechanism.

[0025] In this embodiment, the riveting slot 5 is preferably conical or annular. The riveting slot 5 is conical, which helps the riveted end face 6 to form the riveted flange 3 to fit the inner wall of the riveted slot 5. The riveted slot 5 is annular, which ensures the thickness of the riveted flange 3 formed by the riveted end face 6, so that the riveted flange 3 is not easy to separate from the riveted slot 5.

[0026] Reference Figure 2 A riveting sink groove is provided on the riveting end face 6. Based on the setting of the riveting sink groove, it is helpful for the rivet rod to screw rivet the riveting end face 6, that is, the rivet rod enters the riveting sink groove and screws it, so that the inner wall of the riveting sink groove extends into the riveting slot hole 5, thereby forming the riveted flange 3.

[0027] Based on the setting of the riveted sink groove, the inner bottom end face of the riveted sink groove and the side face of the toothed disc 4 containing the riveted slot hole 5 are located in the same plane. This setting ensures that the end face of the riveted flange 3 formed by the riveted end face 6 and the side face of the toothed disc 4 containing the riveted slot hole 5 are in the same plane, thereby preventing the rivet 1 from protruding out of the toothed disc 4 after riveting and ensuring that the surface of the toothed disc 4 is flat.

[0028] In addition, based on the structural setting of the riveting slot 5, it is possible to install the signal push rod 2 on the rivet 1 whose outer diameter is less than or equal to the rivet hole, and form a rivet flange 3 on the riveting end face 6 in the riveting slot 5, so that the rivet flange 3 cooperates with the riveting slot 5 to stabilize the rivet 1. In the prior art, the outer diameter of the rivet 1 must be equal to the inner diameter of the rivet hole to ensure that the rivet flange 3 formed by the protruding toothed disk 4 will not shake due to the rivet in the rivet hole with a smaller outer diameter.

[0029] The functional principle of the utility model can be explained through the following operation modes:

[0030] First, after the rivet 1, the signal push rod 2 and the toothed disc 4 are assembled, they are placed on the riveting fixture, and the riveted end face 6 is screw-riveted with a rivet rod with a diameter smaller than the riveting slot 5. After riveting, the riveted flange surface 3 can be no higher than the surface of the toothed disc 4.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
