[0019] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figure 1 , 2 As shown in Figures 3 and 4, a clamping tool for sapphire inspection includes a hand-held cylinder 1. A guide rod 5 is slidably installed in the middle of the hand-held cylinder 1. A positioning component 4 is arranged on the hand-held cylinder 1. The hand-held cylinder 1 is connected to the guide rod 5 through the positioning component 4. A sliding plate 7 is slidably installed between the inner walls of the hand-held cylinder 1. One end of the guide rod 5 is arranged on the upper surface of the sliding plate 7. A plurality of grooves 10 are equidistantly arranged on the lower surface of the sliding plate 7. A plurality of rotating shafts 11 are rotatably installed between the inner walls on both sides of each groove 10. A gripping arm 3 is fixedly installed on the side surface of each rotating shaft 11.

[0021] As Figure 1 As shown in Figure 5, a top plate 6 is fixedly installed at the upper end of the guide rod 5, which is convenient for the staff to pull the guide rod 5.

[0022] As Figure 1 As shown in Figure 6, anti-slip patterns 2 are arranged in the middle of the hand-held cylinder 1, which can improve the stability when the staff holds the hand-held cylinder 1.

[0023] As Figure 1 As shown in Figure 7, protective gaskets 12 are arranged on the inner walls at the tops of the gripping arms 3 to prevent the gripping arms 3 from scratching the surface of the gemstone.

[0024] As Figure 3 , 4 As shown in Figures 8 and 9, chutes 8 are arranged on the inner walls of the hand-held cylinder 1. Slide blocks 9 are fixedly installed on both sides of the sliding plate 7. The slide blocks 9 are slidably installed inside the chutes 8, which can improve the stability when the sliding plate 7 moves.

[0025] As Figure 2 , 3As shown in FIGS. 5, the positioning component 4 includes a plurality of positioning grooves 401, guide grooves 402, and a positioning plate 405. The plurality of positioning grooves 401 are equidistantly formed on the side surface of the guide rod 5. The guide groove 402 is formed on the upper surface of the hand-held cylinder 1. The positioning plate 405 is slidably mounted on the upper surface of the hand-held cylinder 1. The positioning plate 405 is disposed inside the positioning groove 401. A guide block 404 is slidably mounted inside the guide groove 402. The guide block 404 is connected to the positioning plate 405. A pull plate 406 is fixedly mounted on the upper surface of the positioning plate 405. A spring 403 is fixedly mounted on the inner wall of the guide groove 402. One end of the spring 403 is disposed on the side surface of the guide block 404. By the staff pulling the pull plate 406 outwards, the positioning plate 405 is pulled out from the inside of the positioning groove 401. At this time, the staff can slide the guide rod 5 upwards and simultaneously slide the sliding plate 7 upwards. And because the plurality of gripper arms 3 are arranged to rotate obliquely, when the sliding plate 7 moves upwards, the plurality of gripper arms 3 will close. When the sliding plate 7 moves downwards, the plurality of gripper arms 3 will spread outwards. When the plurality of gripper arms 3 close, the sapphire will be gathered between the plurality of gripper arms. At this time, by the staff releasing the pull plate 406, due to the elasticity of the spring 403, the guide block 404 will be reset, and at the same time the positioning plate 405 will be reset into the positioning groove 401, playing a role in fixing the guide rod 5 to prevent the guide rod 5 from sliding again. The sapphire set between the plurality of gripper arms 3 will not fall, facilitating the staff to comprehensively observe the sapphire.

[0026] The working principle of the clamping tool for sapphire inspection:

[0027] When in use, when this device is needed to clamp the sapphire, the sapphire is set between the plurality of gripper arms 3. At this time, by the staff pulling the pull plate 406 outwards, the positioning plate 405 is pulled out from the inside of the positioning groove 401. At this time, the staff can slide the guide rod 5 upwards and simultaneously slide the sliding plate 7 upwards. And because the plurality of gripper arms 3 are arranged to rotate obliquely, when the sliding plate 7 moves upwards, the plurality of gripper arms 3 will close. When the sliding plate 7 moves downwards, the plurality of gripper arms 3 will spread outwards. When the plurality of gripper arms 3 close, the sapphire will be gathered between the plurality of gripper arms. At this time, by the staff releasing the pull plate 406, due to the elasticity of the spring 403, the guide block 404 will be reset, and at the same time the positioning plate 405 will be reset into the positioning groove 401, playing a role in fixing the guide rod 5 to prevent the guide rod 5 from sliding again. The sapphire set between the plurality of gripper arms 3 will not fall, facilitating the staff to comprehensively observe the sapphire.

[0028] The above embodiments of the present utility are merely examples for clearly illustrating the present utility, rather than limitations on the implementation modes of the present utility. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation modes here. Any obvious changes or modifications derived from the technical solutions of the present utility still fall within the protection scope of the present utility.
