The connecting cylinder 303 and the supporting disk 304 are made in one piece to increase the connection strength.

[0049] In another example, the axially arranged connecting cylinder 303 and the supporting disc 304 are connected by a positioning connection structure (not shown), wherein the positioning connection structure includes a positioning groove and a positioning protrusion. Specifically, in one structural setting, the positioning groove is arranged on the bottom radial end face of the connecting cylinder 303, and correspondingly, the positioning protrusion is arranged on the upper radial end face of the supporting disc 304, and the connecting cylinder 303 and the supporting disc 304 are connected to each other by the positioning protrusion being clamped in the positioning groove. Further, it should be supplemented that in order to improve the stability of the positioning connection, and based on the circular structure of the connecting cylinder 303 and the supporting disc 304, the number of positioning grooves is set to multiple, and the multiple positioning grooves are distributed at intervals along the circumferential direction on the bottom radial end face of the connecting cylinder 303. In the preferred example, the number of positioning grooves is set to at least three, and the angle formed by every two adjacent positioning grooves is 120 degrees. Correspondingly, the number of the positioning protrusions is set to be multiple, and the multiple positioning protrusions are distributed at intervals along the circumferential direction on the upper radial end surface of the support disk 304 and are arranged one-to-one correspondingly to the positioning grooves.

The diameter of the supporting disc 304 is larger than the diameter of the connecting cylinder 303.

[0053] In this embodiment, the first connecting structure 302 includes an annular groove, and the annular groove is arranged on the outer peripheral surface of the damping element 30. Correspondingly, the second connecting structure 201 includes an annular protrusion arranged on the inner peripheral surface of the first through-hole cylinder 202 of the connecting portion. The annular protrusion is clamped in the annular groove to limit the freedom degree of the damping element 30 relative to the connecting portion in the axial direction.

Correspondingly, the second connecting structure 201 includes an annular groove arranged on the inner peripheral surface of the first through-hole cylinder 202 of the connecting portion. The annular protrusion is clamped in the annular groove to limit the freedom degree of the damping element 30 relative to the connecting portion in the axial direction. Further, corresponding to the specific structure of the damping element 30, the annular protrusion is arranged on the outer peripheral surface of the connecting cylinder 303.

Correspondingly, a plurality of first protrusions are provided on the lower end surface of the connection sleeve 204, and the plurality of first protrusions are arranged at intervals along the circumferential direction on the lower end surface of the connection sleeve 204. Each first protrusion corresponds to each first card slot, and each first protrusion is clamped with each first card slot to realize the connection between the upper end surface of the support disc 304 and the lower end surface of the connection sleeve 204. In this embodiment, the lower end surface of the connection sleeve 204 specifically refers to the circumferential end surface of the peripheral wall of the sleeve hole forming the connection sleeve 204.

[0056] In one example, the plurality of first card slots and the plurality of first protrusions can also be arranged as follows: A plurality of first protrusions are provided on the upper end surface of the support disc 304, and the first protrusions are arranged at intervals along the circumferential direction on the radial end surface of the support disc 304.

In this embodiment, the lower end surface of the connection sleeve 204 specifically refers to the circumferential end surface of the peripheral wall of the sleeve hole forming the connection sleeve 204.

[0057] In this embodiment, in order to improve the supporting ability of the damping element 30, a positioning support member 50 is further provided. The positioning support member 50 is sleeved in the second through hole 301 of the damping element 30 to form a positioning support for the damping element 30. A third through hole 504 is provided at the center of the positioning support member 50.

[0058] Specifically, the positioning support member 50 includes a lining sleeve, and the lining sleeve includes a support column 501, a first limiting shoulder 502, and a second limiting shoulder 503 that are integrally formed; wherein, the support column 501 is sleeved in the second through hole 301 of the damping element 30, and a third through hole 504 is provided at the center of the support column 501. The first limiting shoulder 502 and the second limiting shoulder 503 are respectively provided at the upper and lower ends of the support column 501.

The second limiting shoulder 503 is the fourth connecting structure, and the third connecting structure 305 includes a limiting groove provided on the inner peripheral surface of the support disc 304.

[0059] It should be added that, in one example, the positioning support member 50 can be injection molded or integrally molded with the damping element 30 by overmolding. Of course, it can also be separately assembled as described in the above example.
