[0025] As shown in the figure: Figures 1-4

[0026] A jewelry inlay clamping device, comprising a base 101 and a support plate 102 fixed on the upper surface of the base 101, one side of the support plate 102 is fixedly installed with a square rod 103;

[0027] An arc-shaped abutment plate 104 is provided with four groups and is annularly and equidistantly distributed outside the square rod 103, a plurality of symmetrical telescopic rods 106 are fixed between the arc-shaped abutment plate 104 and the square rod 103, a rectangular groove corresponding to the arc-shaped abutment plate 104 is formed on the surface of the square rod 103, and the plurality of telescopic rods 106 are located in the rectangular groove, springs 107 are wound on the surface of the plurality of telescopic rods 106, and the two ends of the springs 107 are fixedly connected with the square rod 103 and the arc-shaped abutment plate 104 respectively;

[0028] A sliding opening 105 adapted to the arc-shaped abutment plate 104 is formed on the support plate 102;

[0029] A U-shaped plate 108 is fixedly installed on the side of the support plate 102 away from the square rod 103;

[0030] A screw rod 109 is threadedly connected at a threaded hole formed in the U-shaped plate 108;

[0031] A conical block 110 is rotatably installed at one end of the screw rod 109 through a bearing, the conical block 110 is provided with four symmetrical inclined surfaces, one end of the arc-shaped abutment plate 104 corresponds to the inclined surface of the conical block 110, symmetrical limiting rods 111 are fixedly installed on the side of the conical block 110 close to the screw rod 109, limiting holes adapted to the limiting rods 111 are formed in the U-shaped plate 108, and the limiting rods 111 can slide in the limiting holes formed in the U-shaped plate 108.

[0032] ​In this embodiment: when the ring needs to be supported and fixed, first, the ring is sleeved on the annular column composed of multiple groups of arc-shaped abutting plates 104, and then the screw rod 109 is rotated. Since the screw rod 109 is threadedly connected with the U-shaped plate 108, rotating the screw rod 109 can move the U-shaped plate 108, thereby driving the conical block 110 to move synchronously. The conical block 110 is provided with two groups of limiting rods 111, which slide in the limiting holes of the U-shaped plate 108, and are used for limiting the conical block 110 to ensure the stability of the movement of the conical block 110;

[0033] The conical block 110 is designed as a four-equal-inclination surface, one end of the arc-shaped abutting plate 104 corresponds to the inclination surface of the conical block 110. With the movement of the conical block 110, the arc-shaped abutting plate 104 is extruded, and multiple groups of arc-shaped abutting plates 104 are synchronously expanded outward. The arc-shaped abutting plate 104 can slide in the sliding opening 105 of the support plate 102.

[0034] Multiple groups of arc-shaped abutting plates 104 are synchronously expanded outward, thereby stretching the multiple-section telescopic rods 106 and the springs 107. The multiple-section telescopic rods 106 ensure the stability of the connection between the arc-shaped abutting plate 104 and the square rod 103, and the springs 107 are arranged to automatically drive the arc-shaped abutting plate 104 to be attached to the square rod 103 and reset when the extrusion on the arc-shaped abutting plate 104 is released.

[0035] Through the synchronous expansion of multiple groups of arc-shaped abutting plates 104, the device can effectively support and fix the ring. The present scheme adopts a new driving mechanism, which can drive four groups of arc-shaped abutting plates 104 to move away from or close to each other by only one screw rod 109, thereby realizing the rapid support and fixation of the ring. This improvement significantly improves the efficiency of support and fixation, simplifies the operation steps and time, enhances the use effect of the structure, and meets the actual use requirements.

[0036] It should be noted that the mounting holes are arranged at the four corners of the base 101. The base 101 can be fixed and installed at a specified appropriate position by penetrating the mounting holes with bolts and cooperating with nuts.

[0037] The arc-shaped abutting plate 104 is provided with a limiting and clamping mechanism. The components used by the limiting and clamping mechanism are disclosed in the publication No. CN221059777U, and the use effect can be referred to the publication No. CN221059777U (i.e., the second bidirectional screw rod, clamping plate and shaft part disclosed in the prior art). The contents not described in detail in the limiting and clamping mechanism in the present specification all belong to the prior art known by those skilled in the art.

[0038] Furthermore,

[0039] In an alternative embodiment, the arc-shaped abutting plate 104 is provided with a strip-shaped slot near one end of the frustum block 110, and a roller 112 is arranged in the strip-shaped slot and rotatably connected to the arc-shaped abutting plate 104 through a rotating shaft.

[0040] In the embodiment, one end of the arc-shaped abutting plate 104 is provided with the roller 112, and the roller 112 is in contact with the inclined surface of the frustum block 110, so that the friction between the frustum block 110 and the arc-shaped abutting plate 104 is reduced, and the smoothness of the extrusion process is improved.

[0041] The working principle and use process of the jewelry inlay clamping device are as follows: in the use process, when it is necessary to support and clamp a ring, the ring is first sleeved on the annular column composed of multiple arc-shaped abutting plates 104, and then the screw rod 109 is rotated to drive the frustum block 110 to move synchronously, the frustum block 110 is designed as a four-equal-inclined surface, one end of the arc-shaped abutting plate 104 corresponds to the inclined surface of the frustum block 110, with the movement of the frustum block 110, the arc-shaped abutting plate 104 is extruded, and multiple arc-shaped abutting plates 104 are expanded outward synchronously; through the synchronous expansion of multiple arc-shaped abutting plates 104, the device can effectively support and fix the ring, the device adopts a novel driving mechanism, and only one screw rod 109 is needed to drive four arc-shaped abutting plates 104 to move away from or close to each other, so that the ring can be quickly supported and fixed, the improvement significantly improves the efficiency of support and fixation, simplifies the operation steps and time, enhances the use effect of the structure, and meets the actual use requirement.

[0042] Finally, it should be pointed out that: the above-mentioned is only the preferred embodiment of the utility model, and is not used for limiting the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, still can modify the technical scheme recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features.
