Abstract

The invention discloses a multifunctional pencil sharpener. The multifunctional pencil sharpener comprises a pencil rotating assembly and a printing assembly. The pencil rotating assembly comprises a pencil sharpener shell and a blade. A pencil rotating groove is formed in the surface of the pencil sharpener shell. The blade is arranged in the pencil rotating groove. The printing assembly comprises a seal shell and an idler wheel type seal mounted in the seal shell. A pattern layer is arranged on the surface of the idler wheel type seal. The seal shell is connected to an opening in the lower end of the pencil sharpener shell through an intermediate connecting body. An inner cavity of the seal shell, an inner cavity of the intermediate connecting body and an inner cavity of the pencil sharpener shell are communicated. A filter screen used for separating wood chips from graphite particles is arranged in the inner cavity of the intermediate connecting body or the inner cavity of the pencil sharpener shell. The multifunctional pencil sharpener has the advantages that when a pencil is sharpened, graphite dust enters the inner cavity of the intermediate shell by penetrating through the filter screen, the wood chips are left in the pencil sharpener shell, the wood chips can be poured out independently by unscrewing the pencil sharpener shell from the intermediate shell, and environment pollution caused by raising of the graphite dust is avoided.

Description

technical field [0001] The invention relates to stationery, in particular to a multifunctional pencil sharpener. Background technique [0002] Existing pencil sharpeners are generally only used for sharpening pencils, and their functions are specific and single. The graphite dust and sawdust collected by the pencil sharpener are mixed together without separation, and are generally thrown away directly, failing to turn waste into treasure, and the flying of graphite dust will cause environmental pollution. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a multifunctional pencil sharpener, which solves the problem that the existing pencil sharpener has single function, waste graphite dust is not effectively utilized, and pollutes the environment after being dumped. [0004] The technical scheme of the present invention is: a multifunctional pencil sharpener, comprising a pencil sharpener a...
