Therefore, they should not be construed as limitations on this utility model.

[0034] Example 1

[0035] like Figures 1-2 This illustration shows one structural form of the Cuban chain hand-polishing disc. The Cuban chain hand-polishing disc includes a rectangular disc body 1, with vertical baffles 2 arranged around its outer perimeter. Two support bars 3 are arranged along the length of the disc body 1, and spaced apart along the width of the disc. Clamping adjustment components for holding the wooden board used for polishing are detachably mounted on the support bars.

[0036] The clamping adjusting member comprises two identical clamping adjusting structures, which are arranged at intervals on the support strip. Each clamping adjusting structure comprises a support plate 4, two inverted T-shaped clamping plates 5 are slidably connected to the support plate, a threaded rod 6 is sequentially arranged through the two inverted T-shaped clamping plates, and the two ends of the threaded rod are respectively welded to the inner walls of the two vertical stop plates 2 arranged in the length direction of the polishing disc. A fastening bolt 7 is screwed on the threaded rod outside the two inverted T-shaped clamping plates. Each inverted T-shaped clamping plate is provided with a hole corresponding to the threaded rod, and the hole has an inner diameter greater than the outer diameter of the threaded rod, so that the inverted T-shaped clamping plate can be moved horizontally flexibly.

[0037] Specifically, a boss 8 is symmetrically arranged on both sides of the support plate 4, a sliding groove 9 is arranged in each boss, and the two ends of the inverted T-shaped clamping plate extend into the sliding groove. The sliding groove in the boss and the top surface of the support plate together form a sliding channel for the inverted T-shaped clamping plate to slide.

[0038] In use, when the obtained Cuban chain needs to be polished, first adjust the distance between the two inverted T-shaped clamping plates 5 on each support plate 4, so that the initial distance is greater than the thickness of the polishing wood plate 13, then insert the polishing wood plate between the two inverted T-shaped clamping plates, then push the two inverted T-shaped clamping plates on one support plate 4 towards each other until they come into contact with the outside of the polishing wood plate, then tighten the fastening bolts 7 outside the two inverted T-shaped clamping plates to achieve clamping and pressing of the front part of the polishing wood plate; then continue to push the two inverted T-shaped clamping plates on the other support plate according to the same steps above to clamp and press the rear part of the polishing wood plate, ensuring the stability of the wood plate. Apply rosin on the top surface of the wood plate, then lay the Cuban chain on the rosin to achieve bonding and fixing of the Cuban chain on the top surface of the wood plate, and finally the operator uses a corresponding tool to polish the surface of the Cuban chain back and forth by hand. During polishing, for gold and silver chains, the falling metal powder will flow into the disc below with the rosin, achieving collection of the lost metal powder and avoiding waste. After polishing, the fallen rosin and metal powder are poured out for sintering or directly sintered in the polishing disc to recover the metal powder.

[0039] Example 2

[0040] As Figures 3-4 , another structure of the Cuban chain manual polishing disc is shown, and the structure of the clamping adjusting member adopts a more simple flat-nose pliers 11, and a rotating rod 12 is connected to the outer end of the threaded rod of the flat-nose pliers structure through a shaft. The flat-nose pliers are adjusted on the right side of the polishing disc to clamp the polishing wood plate. A waist hole 10 is provided on the base of the flat-nose pliers, and a fastening bolt 7 is arranged in the waist hole; the flat-nose pliers are integrally moved and adjusted along the width direction of the disc body through the waist hole and the fastening bolt.

[0041] The structure guarantees good clamping of the polishing wood plate, and realizes more convenient adjustment.

[0042] The above specific embodiments cannot be used as a limitation to the protection scope of the utility model, and any alternative improvement or change made by the person skilled in the art to the utility model embodiments falls within the protection scope of the utility model.

[0043] The unexplained parts of the utility model are the common technology of the person skilled in the art.
