Description

technical field [0001] The invention relates to the field of pencil sharpeners, in particular to a pencil sharpener capable of cutting nibs of different shapes and sizes. Background technique [0002] Pencil is an indispensable tool in learning, working and living, especially for primary school students or for sketching and drawing. There is a layer of wooden skin wrapped around the outside of the pencil. When using it, you need to use a pencil sharpener to peel off the skin before you can use it. In the process of writing, drawing, and drawing lines, there are different requirements for the shape, thickness, and length of the pencil tip. Today's Pencil sharpeners are often difficult to meet. When flat shapes or other shapes are needed in the process of writing, drawing, drawing and drawing lines, it is necessary to use a knife to manually cut, which is inefficient, and using a knife to cut is likely to cause injury to children. In view of the above problems, it is of grea...
