Ring with two clamping pins

Abstract

A ring device made of metal; the ring device comprising: a ring body; two clamping pins extending from the ring body; a surface of the pin facing the pin having a first groove and a surface of the pin facing the pin having a second groove; the ends of the pins expanding outwards so as to form with a clamping portion; and a jewel placed in the clamping portion to be clamped by the two pins; edges of the jewel embedding into the first and second grooves to be fixed therein. In assembly, a fixture compresses the ring inwards so that the two pins expand outwards; then the jewel is placed in the clamping portion so that the edges of the jewel are received into the first and second grooves of the pins.

1 . A ring device made of metal; the ring device comprising: 
 a ring body;    two clamping pins extending from the ring body; a surface of a first pin of the two pins facing a second pin of the two pins having a first groove and a surface of the second pin facing the first pin having a second groove; the ends of the pins expanding outwards so as to form with a clamping portion;    a jewel placed in the clamping portion to be clamped by the two pins; edges of the jewel embedding into the first and second grooves to be fixed therein;    wherein in assembly, a fixture compresses the ring inwards so that the two pins expand outwards; then the jewel is placed in the clamping portion so that the edges of the jewel are received into the first and second grooves of the pins; then the fixture is released; therefore, by the resilient force of the ring, the two pins will restore to clamp the positioning portion of the jewel.
