The center of the protective plate 20 is rotatably connected with a placement plate 19 for placing jade.

[0023] When the user places the jade, the user opens the safety door 2 and places the jade on the placement plate 19.

[0024] A third slide groove 25 is provided on the base plate 24 and is arranged perpendicular to the fourth slide groove 26. A guide rod 29 is fixedly installed on the front and rear inner walls of the third slide groove 25. The third slide groove 25 has a built-in third slider 31.

[0027] When testing is required, the user drives the second gear 33 to rotate through the first motor 32. At this time, the rotation of the first gear 21 drives the placement plate 19 to rotate, thereby changing the position of the jade covered by the spectrum.

[0028] The jade fixing mechanism includes a second slider 18, a second motor 34, a second threaded rod 35, a second slide 36 and a splint 37. A second slide 36 is opened in the middle of the top of the placement plate 19. The second threaded rod 35 is rotatably installed on the front and rear inner walls of the second slide 36.

The built-in threads of the two groups of second sliders 18 are oppositely arranged. A splint 37 is fixedly installed on the top of the second slider 18, and the corresponding side walls of the splint 37 are provided with rubber pads.

[0029] When the jade is placed on the placement plate 19, the second motor 34 is driven to rotate, causing the second threaded rod 35 to rotate. At this time, the two sets of second sliders 18 move toward each other, causing the two sets of clamps 37 to fit against the outer wall of the jade, thereby completing the clamping and fixing of the jade.

[0030] The jade detection mechanism 4 includes an electric push rod 5, a drive ring 6, a positioning pin 17, a connecting frame 38, a fixing ring 39, a third motor 40, a fixing frame 41, a third gear 42, teeth 43 and a multi-spectral fusion detector 44.

[0031] When jade detection is required, the user drives the electric push rod 5 to cause the multi-spectral fusion detector 44 to move longitudinally, and the lens of the multi-spectral fusion detector 44 is close to the surface of the jade. When the multi-spectral fusion detector 44 is driven, the jade can be irradiated and jade data can be collected. At the same time, the third motor 40 is driven to drive the third gear 42 to rotate, causing the drive ring 6 to rotate, thereby changing the position of the multi-spectral fusion detector 44, irradiating other parts of the jade, and further collecting data.

[0033] Working principle: When the user places the jade, the user opens the safety door 2, and the user pulls the fixing plate 22 through the operating slot 23, causing the fixing plate 22 to extend outside the detection box 1, and the user places the jade on the placement plate 19. After placement, the user pushes the fixing plate 22 to reset the fixing plate 22, and at the same time drives the second motor 34 to rotate, causing the second threaded rod 35 to rotate. At this time, the two groups of second sliders 18 move toward each other, causing the two groups of clamping plates 37 to fit with the outer wall of the jade, thereby completing the clamping and fixing of the jade; When jade detection is required, the user drives the electric push rod 5 to cause the multi-spectral fusion detector 44 to move longitudinally, and the lens of the multi-spectral fusion detector 44 is close to the surface of the jade. When the multi-spectral fusion detector 44 is driven, the jade can be irradiated and jade data can be collected. At the same time, the third motor 40 is driven to drive the third gear 42 to rotate, causing the drive ring 6 to rotate, thereby changing the position of the multi-spectral fusion detector 44, irradiating other parts of the jade, and further collecting data.
