Ceramic pencil sharpener capable of greatly increasing pencil sharpening times
The ceramic pencil sharpener capable of greatly improving the pencil sharpening times comprises a tool apron and a blade, the blade is installed on the tool apron, a cutting edge is arranged on one side of the blade, a pencil groove is formed between the cutting edge and the tool apron and used for containing pencils, the blade is a ceramic blade, and the cutting edge is arranged on the other side of the blade. And the included angle between the cutting edge surface of the ceramic blade and the horizontal plane is 30.5-34 degrees. According to the pencil sharpener, the ceramic blade is adopted, so that the pencil sharpener is high in hardness, rustless, durable and not prone to passivation, and the pencil sharpening frequency can be increased by more than 20 times.
本发明涉及一种可大幅提高削笔次数的陶瓷削笔刀，该可大幅提高削笔次数的陶瓷削笔刀，包括刀座、刀片，所述刀片安装在所述刀座上，且所述刀片的一侧设有刃口，所述刃口与所述刀座之间设有笔槽，用于放置铅笔，所述刀片是陶瓷刀片，且所述陶瓷刀片的刃口面与水平面的夹角角度为30.5‑34°。本发明的削笔刀采用的是陶瓷刀片，硬度高、不生锈、耐用，不容易钝化，削笔次数可提高20倍以上。
