Abstract

The invention discloses a handheld pencil sharpener. The hand-held pencil sharpener comprises a front cover, a shell, a tool core, an automatic pencil advancing mechanism, a handle, an inner gear, transmission teeth, a rack, a back cover and a torsional spring, wherein the shell comprises two parts; one part is used for accommodating a pencil sharpening mechanism, and the other part is a handheld part, thereby constructing a handle mechanism with the handle; a handle shaft is connected to the shell; the rack is fixed on the handle shaft; one end of the torsional spring is fixed on the rack, and the other end of the torsional spring is fixed on the handle; the rack is meshed with the transmission teeth; the transmission teeth are meshed with the inner gear; the inner gear is matched with the tool core; the automatic pencil advancing mechanism, the tool core, the inner gear and the transmission teeth are fixed in sequence in the shell; the lower side of the tool core is inserted into a scrap box; the front part of the shell is covered by the front cover, and the back part of the shell is covered by the back cover. The handle is held with a hand, the rack and the gear are driven through reciprocating pressing between the handle and the shell, and the tool core is driven to rotate for sharpening a pencil, so that a user can apply force easily, force is saved, and convenience is brought to operation.

Description

technical field [0001] The invention relates to a pencil sharpener. Background technique [0002] Existing pencil sharpeners include two types: hand-operated pencil sharpeners and electric pencil sharpeners.
