Problems solved by technology

[0002] In the prior art, there are two kinds of pencil sharpeners: electric type and hand-operated type. The electric type pencil sharpener is driven by a motor to automatically sharpen the pencil, which is convenient to use. However, the traditional electric pencil sharpener waste battery is not energy-saving and environmentally friendly. When the power is insufficient or there is no external power supply, it cannot be used, and it is not conducive to improving children's hands-on ability; the traditional hand-operated pencil sharpener is manually sharpened by manually rotating the pencil, and the pencil sharpener is easy to shake during the pencil sharpening process, and the The pen tool is easy to eccentric during the pen process, which may easily cause core breakage and damage to the blade. In addition, the traditional hand-operated pencil sharpener is difficult to use, and the blade is damaged and should not be disassembled and replaced.
