[0031] The inner ring body 2 is composed of two identical first arc-shaped ring bodies 21 and two identical second arc-shaped ring bodies 22;

[0032] The first arc-shaped ring bodies 21 and the second arc-shaped ring bodies 22 are alternately connected;

[0033] One end of the spring piece 3 is connected to the first arc-shaped ring body 21, and the other end is connected to the second arc-shaped ring body 22; the spring piece 3 is an arch structure, and both ends of the spring piece are folded outward to form a right-angle folded edge 31, and a limiting cross bar 32 is provided on the spring piece.

[0034] Preferably, both ends of the inner ring body 2 are provided with outer edges 20 extending radially outward.

[0035] Preferably, both ends of the limiting cross bar 32 are fixed on the outer edge 20 .

[0036] Preferably, a limiting edge 23 is provided on the outer edge 20 and extends axially along the inner ring body 2 .

[0037] Preferably, a groove 24 and a protrusion 25 are respectively provided at two ends of the first arc-shaped ring body 21 and the second arc-shaped ring body 22 .

[0038] Preferably, the body 1 has a U-shaped cross section, and an edge 11 is provided at the U-shaped opening.

[0039] Specifically,

[0040] The main body 1 and the inner ring body 2 are both elliptical ring body structures. The inner ring body 2 is composed of two identical first arc-shaped ring bodies 21 and two identical second arc-shaped ring bodies 22. The first arc-shaped ring bodies 21 and the second arc-shaped ring bodies 22 are alternately connected.

[0041] A groove 24 and a protrusion 25 are respectively provided at both ends of the first arc-shaped ring body 21 and the second arc-shaped ring body 22 . When the first arc-shaped ring body 21 and the second arc-shaped ring body 22 are connected, the protrusion 25 is adapted to be inserted in the groove 24 .

[0042] The inner ring body 2 has outer edges 20 extending radially outward at both ends, and both ends of the limiting cross bar 32 are fixed on the outer edges 20; the limiting cross bar 32 can be welded on the outer edge 20, or an adaptive hole is opened on the outer edge 20 for plugging the limiting cross bar 32.

[0043] The spring piece 3 is an arched structure, and both ends of the spring piece 3 are folded outward to form a right-angled edge 31 . The limiting cross bar 32 is arranged above the spring piece 3 and located on the inner side of the right-angled edge 31 .

[0044] The spring piece 3 is connected across the connection between the first arc-shaped ring body 21 and the second arc-shaped ring body 22, with one end connected to the first arc-shaped ring body 21 and the other end connected to the second arc-shaped ring body 22, so as to limit the inner ring body through the elasticity of the spring piece.

[0045] In the present application, the spring piece 3 is arranged on the inner ring body 2 , but the spring piece 3 does not contact the inner wall of the main body 1 .

[0046] The cross section of the main body 1 is U-shaped, and an edge 11 is provided at the U-shaped mouth. A limiting edge 23 is provided on the outer edge 20 and extends axially along the inner ring body 2. The limiting edge 23 is restricted by the edge 11 to ensure that the inner ring body 2 as a whole will not be offset in the main body 1.

[0047] When the first arc-shaped ring body and the second arc-shaped ring body are alternately connected to form the inner ring body, the inner ring body is limited by movably fixing the two ends of the arched spring piece to the first arc-shaped ring body and the second arc-shaped ring body respectively.

[0048] When worn, the inner ring body 2 is stretched by the palm, and the first arc-shaped ring body 21 and the second arc-shaped ring body 22 move, thereby compressing the spring piece 3 to expand; when the bracelet is put on the wrist, the inner ring body 2 is separated from the stretch of the palm, and the first arc-shaped ring body 21 and the second arc-shaped ring body 22 are moved to return to a closed state under the action of the spring piece 3. Due to the arched structure of the spring 3, it returns to its original state without being subjected to force, thereby realizing the connection between the first arc-shaped ring body 21 and the second arc-shaped ring body 22, and the two ends of the spring piece 3 are movably fixed on the first arc-shaped ring body 21 and the second arc-shaped ring body 22, respectively, to solve the problem of easy sticking.
