The first fork head and the second fork head respectively comprise a plurality of cleaning teeth 121, which are used to be inserted into the classification wheel grid gaps, and the plurality of cleaning teeth 121 are used to clean a plurality of classification wheel grids 2 at one time; the plurality of cleaning teeth 121 are distributed at intervals so that each cleaning tooth 121 can be inserted into a corresponding classification wheel grid gap; the classification wheel grid gaps gradually increase from inside to outside (i.e. from the rotation center of the classification wheel to the outside in the radial direction), and therefore the cross section of the cleaning tooth 121 gradually decreases from the root to the tip, so as to ensure that the tooth surface of the cleaning tooth 121 is in contact with the grid, thereby cleaning the adhered toner and the like; the surface of the cleaning tooth 121 is provided with a friction pattern 122 for improving the friction force with the grid. The width of the cleaning tooth 121 is adapted to the classification wheel grid gap, and the gap of the cleaning tooth 121 is adapted to the thickness of the classification wheel grid 2; by "adapted", it is meant that the first fork head is in clearance fit with the classification wheel grid 2, and the first fork head is used for one-time cleaning to clean the carbon powder accumulated on the surface of the classification wheel grid 2, and the second fork head is in interference fit with the classification wheel grid 2, and the second fork head is used for secondary cleaning to clean the surface of the classification wheel grid completely. The thickness of the cleaning tooth 121 is adapted to the classification wheel grid gap 2, and thus the cleaning tool 1 can be used vertically, and the plurality of cleaning teeth 121 of the same fork head 12 are simultaneously in a classification wheel grid gap for cleaning the more stubborn accumulations on the grid.
