Thus, the second elastic damping body 11 may have a ring groove formed at the first section 1121, the inner circumferential surface of the through hole is fitted to the outer circumferential surface of the ring groove, and the housing 2 is sandwiched between the bottom of the first section 1121 and the top of the second section 1122, so that the second elastic damping body 11 may be prevented from loosening.

In some embodiments, the cross-sectional area of the second segment 1122 increases gradually in a direction adjacent to the first segment 1121. For example, as shown in fig. 4, the cross-sectional area of the first section 1121 increases in order from bottom to top, thereby facilitating entry of the second section 1122 into the housing 2 upon installation.

In some embodiments, the first elastic damping body 12 is disposed around the extension 112 and the connector 3, the inner bore of the first elastic damping body 12 includes a first bore section 121 and a second bore section 122, the cross-sectional area of the first bore section 121 is greater than the cross-sectional area of the second bore section 122, and the extension 112 fits within the first bore section 121.

For example, as shown in fig. 4, the first hole section 121 is disposed above the second hole section 122, the cross-sectional area of the first hole section 121 is larger than the cross-sectional area of the second hole section 122, and the extension 112 extends into the first hole section 121.
