[0021] The bottom of the processing table 1 is fixedly connected to a motor 6, and the output shaft of the motor 6 passes through the processing table 1 and is fixedly connected to the bottom of the detection disk 3. The detection disk 3 is driven to rotate by the motor 6.

[0022] Among them, the fixing mechanism consists of a clamping plate 9, a slider 10 and a connecting plate 14. The two clamping plates 9 are symmetrically distributed on both sides of the through groove 8. The bottom of the clamping plate 9 is fixedly connected to the two sliders 10, and the slider 10 is slidably installed in the slide groove 11 opened on the mounting plate 5. The side ends of the two clamping plates 9 are fixedly connected to the connecting plate 14, and the two connecting plates 14 are connected by an adjusting mechanism. The adjusting mechanism consists of a double-headed screw 13, a fixed side plate 15 and a fixed side plate 15.

The two ends of the two double-headed screws 13 are rotatably connected to the fixed side plates 15, and the two fixed side plates 15 are fixedly connected to the side walls of the mounting plate 5. A handle 16 is rotatably connected to the side wall of a fixed side plate 15. The handle 16 is fixedly connected to the double-headed screw 13, and the outer surface of the handle 16 is frosted.
