The utility model relates to a pencil feeding mechanism for a pencil sharpener. The pencil feeding mechanism comprises a
front cover, a pencil
rubbing wheel, a pencil clamping disc, a wheel shifting disc and a rear cover. Wherein the
front cover is provided with a rib-plate-shaped first supporting part, the pen clamping disc is provided with a cylindrical
barrel-shaped main body, a rib-plate-shaped second supporting part is arranged in the
barrel-shaped main body, a groove for roughly receiving the end part of each pen
rubbing wheel is formed in the second supporting part, and the first supporting part and the second supporting part are matched with each other to clamp the pen
rubbing wheels together. And a pencil feeding gear positioned on the pencil rubbing wheel is meshed with a poking wheel disc positioned between the pencil clamping disc and the rear cover. The
front cover, the pen clamping disc and the rear cover are connected through a plurality of connecting parts located on the front cover, the pen clamping disc and the rear cover respectively. A pencil enters the pencil sharpener through the first pencil inlet hole of the front cover, the second pencil inlet hole defined by the pencil rubbing wheel, the center hole of the dial wheel disc and the third pencil inlet hole of the rear cover so as to carry out the subsequent pencil
sharpening step. The pencil sharpener comprising the pencil feeding mechanism is simple in structure, small in size and more convenient to carry.
