[0019] Beneficial effects of the utility model:

[0020] 1. The transmission device of the cutting machine body drives the rotating shaft to rotate, and the rotating shaft drives the tool to rotate. At this time, it is protected by the safety shield installed on the connecting column. Some sparks and debris flying during the cutting process are protected by the safety shield. When the cutting machine body is pressed downward to rotate to cut the material to be cut, the piston rod of the cylinder pushes the push block downward, so that the splash-proof box drives the trapezoidal block to slide along the movable block. The splash-proof box slides along the limiting ring through the limiting groove and is adjusted to a suitable cutting height. During cutting, some sparks and debris splash from the limiting groove to the outside and are blocked by the baffle, which reduces the impact of sparks and debris flying from the limiting groove to the outside on the staff, thereby improving the protection effect and safety of use.

[0021] 2. When the cutting machine body is pushed downward and the cutter enters the knife groove, the rotating cutter cuts the material fixed on the cutting table. The movable block moves downward synchronously with the cutting machine body, and the spring is compressed. The two slide bars slide along the movable block at the same time through the fixed block. At this time, the hinge seat rotates along the slide bar, and the support block slides along the cutting table through the ball bearing. When the cutting machine body moves downward for cutting, the splash-proof box moves downward synchronously, so that the bottom surface of the splash-proof box is suitable for contact with the top surface of the cutting material, and sparks and debris are blocked, reducing the occurrence of sparks and debris splashing. At the same time, the sparks and debris generated during the cutting process enter the recycling box through the knife groove for unified recycling, reducing the safety problems caused by the sparks and debris falling downward, improving the cutting effect and use efficiency of the desktop cutting machine, and facilitating the adjustment of the height of the splash-proof box to adapt to the cutting materials of different thicknesses and sizes. Through the auxiliary role of the support block and the slide bar, the splash-proof box can be kept close to the horizontal state during the movement, thereby ensuring its stable and smooth movement and use, improving the safety protection effect of the desktop cutting machine, and providing a safer and more efficient working environment for the staff.

[0022] 3. The sparks and debris generated by cutting are blocked by the safety shield and splash-proof box, so that the debris after cutting falls into the recycling box through the knife groove for collection. When the debris is collected to a certain extent, the buckle is separated from the clamp head, and the rotating sealing block rotates along the recycling box through the rotating rod to discharge the collected debris to the outside, which is convenient for the continuous collection and use of the recycling box, reduces the accumulation of debris on the top surface of the cutting table, reduces the frequency of cleaning the cutting table, and improves the overall use efficiency and convenience.
