[0022] In this embodiment, the height of the cutting knife 12 can be adjusted by the lifting assembly, so that explosion-proof slices of different thicknesses can be cut. After the cutting knife 12 is adjusted, the lifting plate 8 is pressed down. The lifting plate 8 is connected to the elastic component inside the lifting frame 3 through the connecting rod 7. The lifting frame 3 acts as a guide rail, so that the cutting knife 12 can move vertically downward to ensure the cutting effect. When the cutting is completed, the staff no longer presses down the lifting plate 8. At the same time, the elastic component pushes the lifting plate 8 to rise, thereby automatically leaving space for convenient collection or placement of new explosion-proof patches from the cutting board 2. The above-mentioned mechanism adopts a purely mechanical structure. Compared with laser cutting, the mechanical structure has the advantages of greater durability and scope of application, and can also cut explosion-proof patches normally in an environment without electricity.

The turntable 14 is arranged on the outside of the top of the cutting box 10, and the size of the cutting knife 12 is the same as the size of the opening 11.

[0026] In this embodiment, the screw rod 13 is threadedly connected to the threaded hole, so the turntable 14 is rotated, and the turntable 14 drives the screw rod 13 to rotate, thereby driving the cutting knife 12 below to rise or fall. The cutting knife 12 and the screw rod 13 are rotatably connected, and the size of the cutting knife 12 is the same as the size of the opening 11. The opening 11 acts as a guide rail at this time, so that the cutting knife 12 can be vertically raised and lowered to ensure that the cutting position remains unchanged each time, thereby improving the standardization of cutting.

[0027] A pair of handles 9 are installed on the lifting plates 8 on both sides of the rotating disk 14 .
