[0029] In the figure, the units with similar structures are denoted by the same reference numerals.

[0030] The present invention provides a new snake-shaped chain including a chain link structure and an elastic strip.

[0031] Please refer to Figures 2 - 4, wherein the link structure includes a support member 11 and a decorative piece 12. The decorative piece 12 is wrapped around the periphery of the support member 11. A connection groove 111 is provided on the periphery of the support member 11, and folded edge portions 121 are provided at both ends of the decorative piece 12. The folded edge portions 121 are snap-fitted into the connection groove 111. This facilitates the disassembly and assembly of the decorative piece 12 on the support member 11, and further facilitates processing and repair operations. The decorative piece 12 is generally made of precious metal material, which also facilitates the recycling of precious metal materials.

[0032] In this embodiment, the two ends of the support member 11 are respectively a plug-in end and a wrapping end. As Figure 2 shown in the figure, the left end of the support member 11 is the plug-in end, and the right end is the wrapping end. In the direction from the wrapping end to the plug-in end, the circumferential perimeter of the support member 11 gradually decreases, which facilitates the mutual plugging of adjacent link structures to achieve a stable connection structure and is also more beautiful as a whole.

[0033] Wherein, a plug-in groove 112 for plugging with the plug-in end is provided on the end face of the wrapping end. When multiple link structures are connected into a new type of snake-shaped chain, one end of the decorative piece 12 and the plug-in end are jointly connected in the plug-in groove 112.

[0034] Wherein, two through holes 113 are axially provided through the support member 11. The through holes 113 are used for an elastic strip to penetrate and connect multiple support members 11 in series.

[0035] Please refer to Figure 1 . The elastic strip penetrates and connects multiple link structures through the through holes 113, and multiple link structures are connected end to end to form an annular chain structure. Specifically, the plug-in end of one support member 11 and its decorative piece 12 are jointly connected in the plug-in groove 112 of an adjacent support member 11.

[0036] Wherein, the elastic strip can be a steel wire strip that can maintain a specific annular structure. The elastic strip has a break, and under the application of an external force, the elastic strip can be expanded by a certain size to facilitate the disassembly and assembly of the link structure and the elastic strip.

[0037] Please refer to Figure 4 . In this embodiment, a convex rib 114 is provided on the outer periphery of the wrapping end, and the decorative piece 12 is in positioning contact with the convex rib 114.

[0039] Please refer to Figure 3, Optionally, a diamond-inserting groove is provided on the support member 11, and a limiting hole for restricting the diamond 13 in the diamond-inserting groove is provided on the decorative piece 12, thereby forming a link structure with diamond decoration.

[0040] Please refer to Figure 4 and Figure 5 , Optionally, a decorative layer 124 is provided on the outer surface of the decorative piece 12, thereby forming a link structure with layer decoration.

[0041] In this embodiment, the cross-section perpendicular to the axial direction of the support member 11 is a polygonal structure, and the decorative piece 12 is provided with a breakable groove 123 corresponding to the axial edge of the outer periphery of the support member 11, so that the decorative piece 12 can be conveniently wrapped and assembled corresponding to the shape of the support member 11.

[0042] The novel snake-shaped chain of this preferred embodiment uses an elastic strip to connect multiple link structures in series to form an annular chain structure. The elastic strip has a break, and under the application of an external force, the elastic strip can be expanded by a certain size to disassemble and assemble the link structure and the elastic strip. Among them, the decorative piece generally uses precious metal materials. By loosening a certain distance between adjacent link structures, the decorative piece on the set support member can be disassembled and assembled, so as to facilitate the processing and repair operations of the local decorative piece, and also facilitate the recycling of precious metal materials.

[0043] In summary, although the present invention has been disclosed above with preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those of ordinary skill in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention is subject to the scope defined by the claims.
