A gradient shield 8 is fixedly connected to one end of the waterproof shaft 7, and the gradient shield 8 is inside the white oil. The gradient shield 8 consists of four shields with different light transmittance.

[0025] By adopting the above technical solution, this protective device can achieve a folding function through the hinges between the front plate 1, the top plate 2, and the rear plate 3. When unfolded for use, the protective door 5 inside the operating port 4 can slide to achieve an opening and closing function. The double-layer glass 6 and the white oil inside can ensure that the operator can observe the working condition of the machine tool when the protective door 5 is closed. When the machine tool generates sparks during processing, the waterproof shaft 7 can be rotated according to the intensity of the sparks to achieve different light-blocking effects. The white oil inside the double-layer glass 6 can provide a good buffering effect when the blade breaks, preventing the blade tip from flying and shattering the glass, thus preventing danger to the operator.

[0026] like Figures 1-5As shown, the outer surface of the front plate 1 and the inner surface of the rear plate 3 are threaded with two fastening screws 9. One end of each fastening screw 9 is rotatably connected to a fastening block 10. The outer surface of each fastening block 10 is fixedly connected to a limiting slide rod 11, and the limiting slide rod 11 slides through and is connected to the interior of each plate.

[0027] Furthermore, a protective plate 12 is fixedly connected to the outer surface of the fastening block 10 above the limiting slide bar 11, and holes for sliding of the protective plate 12 are provided on both the front plate 1 and the rear plate 3. The protective plate 12 can effectively prevent debris from affecting the threaded connection of the fastening screw 9.

[0028] Furthermore, fixing screws 13 are fixedly connected to both sides of the outer surface of the front plate 1 and the rear plate 3 below the fastening screws 9, and a collection box 14 is provided below the fixing screws 13.

[0029] Furthermore, two hanging plates 15 are fixedly connected to the upper surface of the collection box 14, and the outer surface of the hanging plates 15 is provided with preset holes for the fixing screws 13 to pass through.

[0030] Furthermore, a fixing nut 16 is threadedly connected to the outer surface of the fixing screw 13 near the outer side, and a limiting nut 17 is threadedly connected to the outer surface of the fixing screw 13 on the other side of the hanging plate 15.
