After the box door 515 and the cutting box 1 are closed to each other, the limbs of the staff are prevented from entering the cutting box 1, so that the protection capability is better. The elastic sponge 518 is elastic. When the limbs are accidentally located between the box door 515 and the elastic sponge 518, the elastic sponge 518 uses its own elasticity to make it easy for the limbs to squeeze the elastic sponge 518 to the side to avoid damaging the limbs of the staff. After the box door 515 and the cutting box 1 are closed to each other, the cutting process is in a closed environment, and the inner wall of the cutting box 1 can be bonded with silencer cotton to reduce the noise during the cutting process.
