Title: Ring with two clamping pins

Description:
FIELD OF THE INVENTION  
      The present invention relates to rings, and in particular to a ring device, wherein the assembly work can be performed easily and quickly. The ring is a metal ring. The pins clamp the jewel. No claws are used so that the ring will not hurt the clothes or other objects.  
     BACKGROUND OF THE INVENTION  
      Referring to  FIGS. 1 and 2 , a prior art ring is illustrated. The ring has a ring body  10 . A seat  11  is located above the ring body  10 . The seat  11  is formed by a prior art claws  110 . An inner side of each claw  110  has a recess  111 . The jewel  12  is assembled in the seat  11  and is positioned by the claws  10 . The edges  120  of the jewel  12  is corresponding to the grooves  111 . In assembly the prior art ring  1 , an inner upper side of each claw  110  of the seat  11  is formed with the groove  111  by using knives. Then the jewel  12  is placed into the seat  11  so that the edges  120  of the jewels are corresponding to grooves  111  in the inner surfaces of the claws  110 . Then a tool is used to bend the top end of the claw  110  for clamping the jewel  12 .  
      However in assembling the prior art ring  1 , the jewel  12  is placed upon the seat  11  and then the claws  110  serve to clamp the jewel  12 . The machining work is tedious and time-consumed. Thereby the claws  110  easily crack clothes or other objects. Thereby the claws  110  deform and become loose as the jewel  12  is released. Moreover in the machining process of bending the claws  110  for clamping the jewel, it is possible that the claws  12  will crack or hurt the jewel  12 .  
     SUMMARY OF THE INVENTION  
      Accordingly, the primary object of the present invention is to provide a ring device, wherein the assembly work can be performed easily and quickly. The ring is a metal ring. The pins clamp the jewel. No claws are used so that the ring will not hurt the clothes or other objects.  
      To achieve above objects, the present invention provides a ring device which is made of metal. The ring device comprises 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 other pin facing the 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.  
      The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

     DETAILED DESCRIPTION OF THE INVENTION  
      In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.  
      Referring to FIGS.  3  to  6 , the ring device of the present invention has the following components.  
      A metal ring body  2  has two clamping pins  20 ,  21 . A surface of the pin  20  facing the pin  21  has a groove  200  and a surface of the pin  21  facing the pin  20  has a groove  210 . The ends of the pins  20 ,  21  expand outwards so as to form with a clamping portion  22 . A jewel  3  is placed in the clamping portion  22  to be clamped by the two pins  20 ,  21 . Edges of the jewel  3  embed into the groove  200 ,  210  to be fixed therein.  
      In assembly, referring to FIGS.  3  to  6 , a fixture compresses the ring  2  inwards so that the two pins  20 ,  21  expand outwards. Then the jewel  3  is placed in the clamping portion  22  so that the edges  30  of the jewel  3  are received into the grooves  200 ,  210  of the pins  20 ,  21 . Then the fixture is released. Therefore, by the resilient force of the ring  2 , the two pins  20 ,  21  will restore to clamp the positioning portion  22  of the jewel  3 .  
      Advantages of the present invention will be described here. In assembling the jewel, the fixture clamps the ring from the two outer sides of the ring so that the pins expand outwards, and thus the edges of jewel can slide into the grooves  200 ,  210 . The assembly work can be performed easily and quickly.  
      The ring is a metal ring. The pins clamp the jewel. No claws are used so that the ring will not hurt the clothes or other objects.  
      Furthermore, by sliding the edges of the jewels into the grooves, the assembly work is easy and quickly.  
      The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
