[0027] Among them, a connecting block 7 is fixed to the other end of the detection box 1 close to the first servo motor 4, and the other end of the first threaded rod 8 is rotatably connected to the connecting block 7. The first servo motor 4 drives the first threaded rod 8 to rotate. The connecting block 7 is restricted by the first slide groove 6 and will not rotate with the first threaded rod 8, thereby making the connecting block 7 translate horizontally to the left and right inside the first slide groove 6.
[0028] Among them, the connecting rod 10 is set in a U shape, the horizontal height of the laser lamp 11 is at the same horizontal height as the middle of the first slide groove 6, and the connecting rod 10 is driven to slide inside the detection box 1 through the connecting block 7, driving the laser lamp 11 to move and irradiate the outside of the crystal rod. The irradiated light falls on the light intensity sensor 12, and the overall quality of the crystal rod is judged according to the light intensity recorded by the light intensity sensor 12.
[0029] Among them, two second sliders 15 are provided, and the two second sliders 15 are symmetrically arranged about the horizontal horizontal plane in the middle of the detection box 1, and the two second sliders 15 are both threadedly connected to the second threaded rod 14, and the thread directions of the two second sliders 15 are opposite.

Similarly, a corresponding shading plate 3 can be installed on the outside of the second slide groove 13 to prevent external light from entering the interior of the detection box 1 and affecting the detection accuracy of the light intensity sensor 12.

[0033] In the present invention, the box cover 2 is first opened to place the crystal rod to be detected inside the detection box 1, and then the box cover 2 is closed. Then the second servo motor 5 is started to drive the second threaded rod 14 to rotate, thereby driving the two second sliders 15 to move toward the middle at the same time, so that the arc-shaped extrusion plate 16 can better fit the crystal rod. The two extrusion plates 16 move toward the middle at the same time, keep the crystal rod limited and make the crystal rod located in the middle of the detection box 1, and then the first servo motor 4 is started to drive the first threaded rod 8 to rotate. The connecting block 7 is restricted by the first slide groove 6 and will not rotate with the first threaded rod 8, thereby making the connecting block 7 move horizontally left and right inside the first slide groove 6. The connecting block 7 drives the connecting rod 10 to slide inside the detection box 1, and drives the laser lamp 11 to move and irradiate the outside of the crystal rod. The irradiated light falls on the light intensity sensor 12. The overall quality of the crystal rod is judged according to the light intensity recorded by the light intensity sensor 12. The first slide groove 6 and the second slide groove 13 are shielded by the provided light shielding plate 3 to prevent external light from entering the detection box 1 and affecting the detection accuracy of the light intensity sensor 12.
