fig. 3 is a schematic structural diagram according to an embodiment of the present invention;

fig. 4 is a schematic structural diagram according to an embodiment of the present invention.

The specific implementation mode is as follows:

the invention will be further described with reference to the accompanying drawings.

Examples

Generally, when drawing is conducted in sketch practice, a clamp is used for clamping drawing paper, then one or more of a pencil, a charcoal pen and a colored pencil are used for conducting sketch drawing, an existing pencil sharpener is generally arranged on a pencil box or a drawing clamp, but only one friction surface is included, the use requirements of various pencils cannot be met, and the friction surfaces are large in size.

As shown in fig. 1 and fig. 2, the present embodiment provides a sketch pencil sharpener, which comprises a main supporting plate 1, a pencil sharpening column 2 and a powder receiving box 3.

Wherein, the supporting plate 1 with the clamping part 13 is arranged to be clamped on a drawing board (not shown in the figure) through the clamping part 13; the supporting plate 1 is a rectangular plate supported by a plastic plate or a metal plate, the width of the rectangular plate is 5-8cm, the rectangular plate is clamped on the side edge of the drawing board, the clamping part 13 is an elastic sheet connected to the supporting plate 1, a clamping space 101 is formed between the elastic sheet and the supporting plate 1 and used for the drawing board to be inserted into, and the thickness of the clamping space 101 is smaller than that of the drawing board so as to be stably clamped.

Further, in the present embodiment, the pencil sharpener 2 is configured in a triangular prism shape having three rubbing surfaces 21, mainly for three kinds of paintbrushes for general painting, and is rotatable with respect to the support plate 1 so that the student rotates to adjust which rubbing surface 21 is used.

In order to fix the position of the pencil sharpener column 2 conveniently, the friction surface 21 is located outside and is in a stable state, the outer wall of the support plate 1 is provided with a stop strip 14, the stop strip 14 is provided with a groove for limiting the ridge line part of the pencil sharpener column 2, and therefore when the friction surface 21 is outside, the ridge line part on the inner side is clamped in the groove for limiting.

Specifically, as shown in fig. 1 to 3, two rotation bases 11 are provided on the support plate 1, and the sharpener column 2 is disposed between the two rotation bases 11 and can rotate relative to the rotation bases 11. Wherein, the swivel mount 11 and the supporting plate 1 are integrally formed, the length of the pencil sharpener column 2 is 4-5cm, and the pencil sharpener column 2 is preferably made of metal, such as stainless steel or aluminum, and has the advantages of long service life and good friction effect.

Further, as shown in fig. 4, the rotational axis of the sharpening column 2 is parallel to the frictional surface 21. The friction surface 21 comprises a rough grinding part 211 and a fine grinding part 212, wherein the density of the friction particles at the rough grinding part 211 is less than that at the fine grinding part 212, and students can use the rough grinding part 211 or the fine grinding part 212 as required to facilitate grinding into the required pen point shape.

As shown in fig. 1 and 2, the powder receiving box 3 is detachably arranged on the support plate 1 and is positioned below the pencil sharpener column 2; the powder ground by the pen point falls into the powder receiving box 3, wherein a pencil or a carbon pen or the like can be placed in the powder receiving box 3, and due to the arrangement of the pencil grinding cylinder 2, the pen is divided into two parts to place the first placing area 301 and the second placing area 302 of the powder receiving box 3.

In an alternative embodiment, the outer wall of the compact 3 is provided with a raised limit strip (not shown), and the support plate 1 is provided with a groove 12, and the limit strip is configured to be inserted into the groove 12.

The groove 12 and the limiting strip are matched, and the cross section of the groove can be square or dovetail.
