In the invention, when a user uses the device, firstly, a pencil is inserted into the fixing device 4 and the fixing tube 14 to complete the fixing work of the pencil, then the rotating handle 54 drives the rotating column 12 to rotate, the rotating column 12 drives the connecting tube 13 and the fixing tube 14 to rotate, then the connecting rod 15 drives the rotating rod 16 and the cutting knife 17 to rotate, and due to the meshing arrangement of the inner ring tube 18 and the first gear 20, the cutting knife 17 can rotate by itself while rotating along with the fixing tube 14 to complete the cutting work of the pencil, so as to generate wood chip roll and graphite powder, the rotating column 12 can drive the second gear 21 to rotate in the rotating process, then drive the third gear 23 to rotate, the third gear 23 can drive the first helical gear 24 to rotate while rotating, the first helical gear 24 can drive the first connecting rod 29 to move through the first rotating block 28 in the rotating process, and then drive the second connecting rod 31 to rotate through the second rotating block 30, then, the third rotating block 37 drives the second friction plate 35 to slide back and forth along the chute 33, the second friction plate 35 can rub against the first friction plate 32 in a large amount in the process of sliding back and forth, static electricity is generated on the first friction plate 32, and graphite powder is attracted;

the second bevel gear 27 drives the second rotating shaft 26 to rotate in the rotating process, and then drives the disc 45 to rotate, the disc 45 drives the third connecting rod 48 to rotate through the fourth rotating block 46 in the rotating process, and then drives the screen plate 41 to move through the fifth rotating block 47, the screen plate 41 can separate the chips, so that the graphite powder can smoothly pass through the screen plate 41 under the action of electrostatic attraction and then fall into the graphite box 7 without mixing in the chip roll, thereby greatly ensuring the safety of children, the screen plate 41 can be matched with the triangular block 42 to complete the extrusion and kneading of the chip roll in the sliding process, so that the graphite powder attached to the chip roll can quickly fall off and fall into the graphite box 7, further ensuring the safety of children, and the volume of the chip roll can be properly reduced by a large amount of kneading and extrusion, so the full-time of the chip box 5 can be greatly prolonged, the frequency of cleaning by children is greatly reduced, so that the children can use the device more easily;

after the cutting is finished, the rotating column 12 is not rotated any more, so that the screen plate 41 is not subjected to external pressure any more, the return spring 40 can pull the sliding block 39 to slide in the transverse groove 38 under the action of the self elasticity, and then the screen plate 41 is driven to be close to the triangular block 42 and to be attached to the triangular block 42, so that the triangular block 42 can plug the meshes on the screen plate 41 to finish the sealing work, meanwhile, the sealing spring 53 can push the sealing plate 52 to be close to the first friction plate 32 under the action of the self elasticity to finish the sealing work, the residual graphite powder on the first friction plate 32 can fall into the graphite box 7 under the action of gravity to wait for treatment after the static electricity is dissipated, so that after the wood chip box 5 is full, a child can directly open the wood chip box 5 to perform the cleaning work without being damaged by the graphite powder, the safety of the child is greatly guaranteed, and after the related work of the pencil of the child, the adult can rotate the screw 10 to release the fixed state of the locking block 9, and then can pull the graphite box 7 to finish the cleaning work of the graphite powder.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
