Background technique

Pencils are one of the most commonly used stationery. When using pencils, you need to sharpen pencils frequently, and various pencil sharpeners have emerged. However, there are still some shortcomings in the use of current pencil sharpeners: ordinary pencil sharpeners are used by primary school students to sharpen pencils. When sharpening, the tip of the knife is very sharp and sometimes accidentally scratches the fingers of elementary school students, causing injury to elementary school students; the semi-automatic pencil sharpener needs to manually shake the handle when sharpening pencils, which is time-consuming and laborious. For students, especially those in the lower grades, who have little strength in their hands, the use of a pencil sharpener makes their grip strength insufficient, and it is more difficult to sharpen pencils. For this reason, we propose a fully automatic pencil sharpener.
