[0033] During specific use, the hand-held part 8 is pinched to get close to the knife handle 2, and the hand-held part 8 drives the gear 4 to rotate around the first fixed axis 3. The gear 4 drives the knife body 6 to rotate around the second fixed axis 5 through the meshing tooth groove 9. After the knife body 6 rotates, it is exposed from the opening at the bottom of the shell. At this time, the blade 10 is connected with the cleaning component 7, and the cleaning rollers 16 on both sides produce friction with the blade 10 to clean the residue. The snake spring 18 pulls the two groups of cleaning components 7 close to each other, so that when the thickness of the blade 10 changes, the cleaning roller 16 can still abut against the blade 10. When the hand-held part 8 is close to the knife handle 2, the buckle 20 can be snapped into the slot 19 to fix the hand-held part 8, thereby ensuring that the distance that the knife body 6 extends outside the knife shell 1 is fixed. After releasing the hand-held part 8, the reset spring 11 contracts to drive the knife body 6 to rotate around the second fixed axis 5, and the knife body 6 is retracted into the knife shell 1.
