Detailed Description

In order to make the technical problems, technical schemes and beneficial effects to be solved more clear, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

The utility model provides a noble metal pendant, which comprises a rotating component used on the pendant, wherein the rotating component has the advantages of good rigidity and smooth rotation. As shown in fig. 1 and 2, the rotating assembly comprises a collet 1, a bearing 2, a bearing supporting shaft 3 and a rotating body 4, wherein the bearing supporting shaft 3 comprises a first section 31, a second section 32 and a third section 33, the first section 31, the second section 32 and the third section 33 are sequentially connected end to end, the central axes coincide, the bearing 2 is sleeved on the second section 32, the tail end of the third section 33, which is not connected with the second section 32, is fixedly connected with the rotating body 4, the bearing supporting shaft 3 is connected with the collet 1 after being connected with the bearing 2, and a connecting body, which is connected with the bearing supporting shaft 3, can rotate around the central axis of the bearing 2, so as to drive the rotating body 4 to rotate.

Further, as shown in fig. 3 and 4, the collet 1 is in a dish-shaped structure, the middle part is concave, the protruding section 11 is the part with the largest diameter of the collet 1, the protruding section 11 extends outwards from the collet body to form an edge, the edge is used for being connected with a pendant in a fitting way, and when the hanging piece is connected, the hanging piece is located between the protruding section 11 and the rotating body 4, so that the protruding section 11 can prop against the hanging piece, and the hanging piece is prevented from falling off.
