[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] refer to Figure 1-2 and Figure 6 As shown, the present invention provides a pencil sharpener for collecting ash, comprising: a collection box 6 with one open side and the other five sides sealed; a movable plate 1 covering the side of the collection box 6 near the open side; a pencil sharpener body 7 stored in the collection box 6 on the side of the movable plate 1 near the collection box 6; and a through hole 15 through the movable plate 1 aligned with the pencil sharpener body 7, so that the pencil sharpener body 7 is stored between the movable plate 1 and the collection box 6 due to the covering.

[0024] As described above, when using the collection box 6 and movable plate 1 provided by this utility model, the pencil sharpener body 7 is installed on the movable plate 1. When the device is in use, the movable plate 1 is closed on the collection box 6, and the pencil sharpener body 7 is in the collection box 6. The pencil is inserted into the pencil sharpener body 7 through the through hole 15. After rotating the pencil, the generated shavings enter the collection box 6 and are collected by the collection box 6.

[0025] Furthermore, to facilitate the replacement of the pencil sharpener body 7, refer to... Figure 2 , Figure 4 and Figure 6 As shown, two clamping seats 8 are symmetrically arranged on the movable plate 1 to hold the pencil sharpener body 7. Slots 14 are provided on both sides of the pencil sharpener body 7, and the ends of the two clamping seats 8 extend horizontally to engage with the slots 14. The pencil sharpener body 7 can be detachably installed at the through hole 15 via the two clamping seats 8 and the slots 14, facilitating future replacement of the pencil sharpener body 7.

[0026] Furthermore, in order to improve the stability of the movable plate 1 when it is closed, refer to Figure 4-5 As shown, the collection box 6 is also provided with an adsorption block 10 on the side near the movable plate 1, and a magnet 9 is provided on the side of the movable plate 1 near the adsorption block 10. The adsorption block 10 can be adsorbed onto the magnet 9. When the movable plate 1 is closed on the collection box 6, the movable plate 1 and the collection box 6 are magnetically connected by the magnet 9 and the adsorption block 10, preventing the movable plate 1 from detaching from the collection box 6.

[0027] Furthermore, to facilitate viewing the amount of debris in collection box 6, refer to... Figure 1-2 As shown, the side of the collection box 6 also has at least a partially transparent area, within which a transparent plate 5 is installed. The extent of debris collection in the collection box 6 can be observed through the transparent plate 5, facilitating subsequent processing of the collected debris.

[0028] In this utility model, combined with Figure 1-4As shown, the collection box 6 in this embodiment is also provided with a connecting mechanism on both sides to connect with the movable plate 1. The connecting mechanism includes a telescopic rod 2 and a telescopic cylinder 3.
