PURPOSE: A chain connection structure is provided, which keeps beauty of the appearance when being used to noble metal and performs the original function when being used to mechanical device. CONSTITUTION: A chain connection structure is constituted as follows. A monomer(1) is formed in the parallel thread quadrilateral shape. An insertion hole(2) is punched in the center and receiving parts(3) in which the top and bottom sides are flat and the outer circumference is rounded are installed on two corners facing each other in one side. On two corners facing each other in the other side, insertion parts(4) in which the outer circumference is rounded and which has the thickness corresponding to the insertion hole are respectively installed. As the insertion part of the other monomer is inserted into the insertion hole of the receiving part of monomer and is interconnected, the original shape of a chain(100) is kept. |
