(III) advantageous effects

The invention provides a wrapping sleeve special for a round eraser for removing dandruff, which has the following beneficial effects:

(1) the local part of the eraser is exposed outside the round sleeve and directly pushes the eraser on the paper surface, at the moment, the eraser can erase wrongly written characters and rotate, and the surface of the eraser can be scraped and rubbed on the wrapping sheet during rotation, so that mud strips can be removed in time, and the defects caused by manual scratching and reuse are avoided.

(2) When the eraser rotates, the roller can also rotate on the surface of the eraser, the mud strips can be removed through extrusion force during rolling due to the fact that the roller is a circular surface, when the wrapping pieces are scraped, scratches can appear on the surface of the eraser, blocks can easily fall off, and the roller can compact the scratches and the blocks, so that excessive damage to the eraser can be avoided.

(3) The hollow shaft can rotate when the eraser is pushed, at the moment, the gear can rotate on the resistance lug, the rotating speed of the eraser can be reduced, and the friction force between the eraser and paper is improved, so that the phenomenon that the eraser rotates too fast to cause that wrong characters are not cleanly erased can be avoided.

(4) The pulling block can enable the pulling plug to drive the arc supporting piece to deform, so that the whole body of the pulling plug is gradually parallel to the hollow shaft, at the moment, the round hole in the middle of the round eraser is sleeved on the hollow shaft and located at the position of the arc supporting piece, and after the arc supporting piece is loosened, the arc supporting piece returns, so that the inner wall of the eraser can be supported, and the inner wall of the eraser can be stably sleeved on the hollow shaft.

(5) The linkage shaft can drive the piston to move in the cylindrical cavity by pulling the sealing cover, at the moment, the opening of the circular sleeve can be opened, the eraser is conveniently placed into the circular sleeve, on one hand, the eraser can be prevented from being stuck with a large amount of dust, and on the other hand, the eraser can be more conspicuous, and can be prevented from being lost and taken quickly.
