The clamping portion 4 with a tip design is more conducive to the combination between the two, and the structure is more stable; and the multiple tips are sequentially attached in pairs to form a clamping opening 5 with a regular polygonal structure. The design of the regular polygonal structure makes the platinum ring after pre-pressing present a symmetrical structure, which is convenient for the subsequent polishing of the platinum ring, and its structural design is more reasonable.

[0044] Among them, the track groove 7 can be one or more. When each clamping part 4 is provided with a sliding pin 6, there are multiple track grooves 7, and the multiple track grooves 7 correspond to the multiple sliding grooves one by one. When the swing arm 2 swings, the sliding path of the sliding pin 6 is limited by the track groove 7, so that the multiple clamping parts 4 can rotate synchronously to adjust the size of the clamping mouth 5.
