Abstract

The invention discloses a pencil sharpening device which comprises a box body, a push-pull rack set and gear rings. The identical positions of the front side face and the rear side face of the box body are provided with annular track grooves respectively. The gear rings are placed inside the annular track grooves. A circular open hole is formed in the front side face of the box body. The upper side face and the lower side face of the box body are provided with push-pull rack placement holes respectively. A linear track groove is formed between the two push-pull rack placement holes. The push-pull rack is composed of a hand hole end and a rack. Holes for containing fingers are formed in the side face of the hand hole end. Annular protrusions are arranged outside the gear rings and embedded into the annular track grooves. Two straight-forward ratchet wheels are arranged inside the gear rings. A pencil knife is fixedly arranged on one ratchet wheel, and the other ratchet wheel is embedded on the inner walls of the gear rings. The gear rings are located at the two ends of the pencil knife. The pencil sharpening device is reasonable in structure, novel in design and easy and convenient to operate.
