[0029] As Figures 1 to 10 shown, the embodiments of the present utility model include:

[0030] A fixture for diamond, including

[0031] A fixture body 100; an adsorption channel penetrating the upper surface and the lower surface of the fixture body 100 is provided on the fixture body 100; the adsorption channel includes an adsorption port 101, an adsorption cavity 102, and an upper interface 103;

[0033] A connecting member 300; the connecting member 300 includes a connecting pipe 301 and connecting ears 302 arranged on the outer wall edge of the bottom of the connecting pipe 301, the connecting ears 302 can be embedded in the connection groove 200, a limiting ring 303 is further provided on the inner wall edge of the bottom of the connecting pipe 301, a through hole is opened in the middle of the limiting ring 303, and the diameter of the through hole is the same as the inner diameter of the upper interface 103;

[0034] A flow rate detection component; the flow rate detection component is arranged on the bottom surface of the connection groove 200, the flow rate detection component includes a convex block 401, the convex block 401 is located at the edge of the upper interface 103, an installation chamber 402 is provided on the inner side surface of the convex block 401, and a flow rate detection element is arranged in the installation chamber 402, and the flow rate detection element faces the adsorption channel;

[0035] The limiting ring 303 is provided with a notch 305 into which the bump 401 can be inserted and embedded;

[0036] a vacuum tube; the vacuum tube is fixedly assembled with the connecting pipe 301.

[0037] In this embodiment, the inner diameter of the adsorption cavity 102 gradually increases from the adsorption port 101 to the upper interface 103, and the inner diameter of the upper interface 103 is twice that of the adsorption port 101; this technical solution can improve the adsorption effect.

[0038] In this embodiment, the bottom surface of the connecting ear 302 is further provided with a sealing structure, and the sealing structure includes an annular groove 304 provided on the bottom surface of the connecting ear 302 and a first sealing ring 306 embedded in the annular groove 304. This technical solution can improve the sealing effect of the overall device.

[0039] In this embodiment, a sealing gasket is further provided on the upper surface of the connecting pipe 301 located inside the limiting ring 303. This technical solution can improve the sealing effect of the overall device.

[0040] In this embodiment, the diamond fixture further includes a compensation structure, and the compensation structure is arranged on the lower surface of the fixture body 100; the compensation structure includes a compensation groove 701, the compensation groove 701 is concentric with the adsorption port 101 and the diameter of the compensation groove 701 is larger than that of the adsorption port 101, the compensation structure further includes a compensation ring 702 assembled in the compensation groove 701, and the bottom of the compensation ring 702 is higher than the lower surface of the fixture body 100. In this technical solution, the compensation structure is beneficial to prevent the edge of the diamond adsorbed on the adsorption port 101 from contacting the lower surface of the fixture body 100. This design is not only convenient for processing but also convenient for having a gap for buckling when removing the diamond, thus improving the buckling efficiency.

[0041] The working principle of this technical solution is as follows: In the normal state when the diamond is not adsorbed, the vacuum pump connected to the vacuum tube is at the minimum output power, and only maintains a flow rate of 1 - 2 ml / s in the vacuum tube and the adsorption channel. This design is beneficial for energy reduction. When the diamond is adsorbed on the adsorption opening, since the diamond blocks the adsorption port 101, the flow rate detection component at the end of the adsorption channel will detect that the air flow rate in the adsorption channel gradually decreases and tends to 0. After receiving the feedback, the external vacuum pump increases the output power, so that the diamond can be adsorbed on the adsorption port 101 for a long time and the adsorption effect is stable; when the diamond is removed after processing is completed, since the adsorption port 101 is released, the flow rate detection component at the end of the adsorption channel will detect that the air flow rate in the adsorption channel gradually increases and its value quickly exceeds the normal value. After receiving the feedback, the vacuum pump resumes the minimum output power in the normal state, and works repeatedly in this way.

[0042] The beneficial effects of the present utility model are as follows: In this technical solution, diamond is adsorbed on the adsorption port 101 through vacuum negative pressure, which is convenient for adsorption and facilitates the processing of diamond. If you want to remove the diamond, you only need to gently pick it by hand to remove it. The operation is simple and practical.

Any equivalent structure or equivalent process transformation made by using the content of the specification of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
