The first decorative element 21 and the sub-decorative elements 12 can have the same shape structure to maintain overall integrity and aesthetics, or can be changed to different shape structures as needed. When the movable decorative element 2 is in the retracted position, the first decorative element 21, together with the sub-decorative elements 12, forms a three-, four-, or multi-leaf clover structure around the central base 11, thereby achieving overall integrity and a unique aesthetic design.

[0031] In one embodiment, the sub-decorative element 12 and the first decorative element 21 each consist of a heart shape or a leaf shape. The tips of the hearts or the ends of the leaves of the sub-decorative element 12 and the first decorative element 21 are arranged near the central base 11, with the tips of the sub-decorative element 12 being firmly connected to the central base 11.

[0032] As in the Fig. 1 and 4 to 11, in this embodiment, both the sub-decorative element 12 and the first decorative element 21 are heart-shaped, with the tips of the heart of the first decorative element 21 and the sub-decorative element 12 being arranged near the central base 11, and the tips of the sub-decorative element 12 being firmly connected to the central base 11. This arrangement ensures a consistent overall design and aesthetic harmony of the piece of jewelry.

[0033] In a further embodiment, both the sub-decorative element 12 and the first decorative element 21 consist of leaf structures, wherein the leaf structures can be grass leaf or tree leaf structures. The ends of the leaves of the sub-decorative element 12 and the first decorative element 21 are arranged near the central base 11, wherein the ends of the leaves of the sub-decorative element 12 are firmly connected to the central base 11.

[0034] In one embodiment, a first through-hole 111a for inserting the connecting cable 3 and a second through-hole 111b for leading out the connecting cable 3 are provided on the central base 11, wherein the second through-hole 111b corresponds to the cutout A.

[0035] In one embodiment, as in Fig. As shown in Figure 3, the central base 11 comprises a central base body 111, wherein the central base body 111 has a first through-hole 111a for inserting the connecting cable 3 and a second through-hole 111b for extending the connecting cable 3. The second through-hole 111b is arranged to correspond to the cutout A.

[0036] The first through-hole 111a may be a square or round through-hole; the specific shape and size are not limited as long as they allow the insertion of the connecting cable 3. The second through-hole 111b may also be square or round, but the specific shape and size are not limited as long as they allow the insertion of the connecting cable 3. The second through-hole 111b is aligned to correspond to the cutout A, which facilitates the insertion of the connecting cable 3 and its connection to the movable decorative element 2.

[0037] In one embodiment, the fixed decorative element 1 also comprises a first connecting part 13 which is connected to the sub-decorative element 12, wherein the first end of the connecting cable 3 is connected to the first connecting part 13.

[0038] As in Fig. As shown in Figures 1, 4, 7-8, the first connecting part 13 is fixedly connected to the sub-decorative element 12. The first connecting part 13 and the sub-decorative element 12 can be integrally formed or welded; the first end of the connecting cable 3 is detachably connected to the first connecting part 13, which facilitates cleaning, maintenance, and replacement.

[0039] In one embodiment, a limiting channel 5 is provided on the fixed decorative element 1, which is located on the sub-decorative element 12, and the second end of the connecting cable 3 runs successively through the limiting channel 5 and the central base 11.

[0040] The restriction channel 5 is connected to the first through-hole 111a on the central base body 111, which facilitates the passage of the second end of the connecting cable 3, so that the connecting cable 3 passes sequentially through the restriction channel 5 and the central base part 11 to be connected to the movable decorative element 2. To a certain extent, the restriction channel 5 can restrict the slipping of the connecting cable 3. The size of the restriction channel 5 can be adjusted depending on the thickness of the connecting cable 3 used.

[0041] In one embodiment, the number of sub-decorative elements 12 is at least three; the first connecting part 13 is arranged between two adjacent sub-decorative elements 12, and the limiting channel 5 is arranged between two other adjacent sub-decorative elements 12.

[0042] As in Fig. As shown in Figures 4-5 and 8-9, in this embodiment, the number of sub-decorative elements 12 is three, with the first connecting part 13 being arranged laterally between the first and second sub-decorative elements 12. This contributes to stabilizing the center of gravity, while also being concealed, which improves the overall aesthetic appearance. The limiting channel 5 is arranged laterally between the second and third sub-decorative elements 12; if the thickness of the side surfaces of the second and third sub-decorative elements 12 is sufficient, the limiting channel 5 can completely conceal the connecting rope 3 and limit its slipping out, thereby improving the overall aesthetics of the jewelry.

[0043] In one embodiment, a limiting element 6 is provided on the stationary decorative element 1. The limiting channel 5 comprises a proximal end point located near the central base 11 and a distal end point remote from the central base 11. The limiting element 6 is arranged on the sub-decorative element 12 and corresponds to the distal end point of the limiting channel 5. The limiting element 6 serves to hold the connecting cable 3 in the limiting channel 5.

[0044] As in the Fig. 4-6 and 8-10, in this embodiment, the number of sub-decorative elements 12 is three. The restricting channel 5 has a proximal end point near the central base 11 and a distal end point away from the central base 11. The restricting element 6 is arranged laterally between the second and third sub-decorative elements 12 and is fixedly connected to each of the second and third sub-decorative elements 12, respectively, wherein the restricting element 6 corresponds to the distal end point of the restricting channel 5. The restricting element 6 has a semicircular structure. If the thickness of the side surfaces of the second and third sub-decorative elements 12 is insufficient, the connecting cable 3 may easily slip out of the restricting channel 5 from the back of the jewelry. In this case, the restricting element 6 prevents the connecting cable 3 from leaving the restricting channel 5 and ensures that the overall appearance and stability of the jewelry are maintained.

[0045] As in the Fig. 2, Fig. 6 and Fig. As shown in Figure 10, in one embodiment, the central base 11 also includes a main decorative stone 112 and a plurality of positioning pins 113. The central base body 111 has a recess into which the main decorative stone 112 is embedded. The positioning pins 113 uniformly surround the main decorative stone 112 and are arranged in the central base body 111.

[0046] The main decorative stone 112 can be a diamond, agate, jade, pearl, gemstone, or other decorative material that enhances the overall appearance of the jewelry. The number of positioning pins is at least two and serves to position the main decorative stone 112. In this embodiment, there are four positioning pins, which increase the stability of the positioning and the overall aesthetic effect.

[0047] As in Fig. 1, in one embodiment, the movable decorative element 2 also comprises a second connecting part 22. The second connecting part 22 is connected to the first decorative element 21, and the second end of the connecting cable 3 is connected to the second connecting part 22.

[0048] The second connecting part 22 is fixedly connected to the movable decorative element 2, whereby the second connecting part 22 and the movable decorative element 2 can be integrally formed or welded. The second end of the connecting cable 3 is detachably connected to the second connecting part 22, which facilitates cleaning, maintenance, and replacement.

[0049] In one embodiment, the damping element 4 is arranged in the central base body 111. The damping element 4 has a damping channel through which the second end of the connecting cable 3 passes successively through the first through-hole 111a and the damping channel of the damping element 4 and finally exits the second through-hole 111b to be connected to the movable decorative element 2.

[0050] As in Fig. As shown in Figure 3, the damping element 4 in this embodiment is a silicone ball containing a damping channel through which the connecting cable 3 passes. The damping channel creates damping friction with the connecting cable 3, thereby limiting the movement of the connecting cable 3. The damping element 4 is arranged in the central base body 111, which does not affect the structure and aesthetic design of the jewelry.

[0051] When the first decorative element 21 is pulled, the movable decorative element 2 moves relative to the fixed decorative element 1 and moves away from the cutout A. Since the damping element 4 is clamped in the central base body 111, the connecting cable 3 can move relative to the damping element 4. When the desired length is reached, the pulling is stopped. The damping element 4 holds the connecting cable 3 in place due to the damping friction, so that the movable decorative element 2 and the connecting cable 3 do not move due to gravity. This fixes the movable decorative element 2 in the desired position. In this state, the jewelry is in the separated state (as in Fig. 1, Fig. 4 and Fig. 6). The length of the jewelry was adjusted and the design modified to meet the user's functional and aesthetic requirements.

[0052] When the movable decorative element 2 and the fixed decorative element 1 are to be brought together, the connecting cable 3 is pulled. The pull brings the movable decorative element 2 towards the fixed decorative element 1 and back to the cutout A. When the movable decorative element 2 is completely retracted into the cutout A, the pulling is stopped. The damping element 4 holds the connecting cable 3 in place due to the damping friction, so that the movable decorative element 2 and the connecting cable 3 do not move due to gravity. The movable decorative element 2 is fixed in place in the cutout A, whereby the jewelry remains in the joined state (as in Fig. 7, Fig. 8 and Fig. 10). The second connecting part 22 is then concealed in the central base body 111. The length and design of the jewelry were adjusted to improve stability and aesthetic appearance.

[0053] The above is only a specific embodiment of the present utility model, but the scope of protection of the present utility model is not limited thereto. Any modification or replacement easily conceivable by a person skilled in the art within the technical scope disclosed in the present utility model falls within the scope of protection of the present utility model. Therefore, the scope of protection of the present utility model shall be subject to the appended claims.
