Push type pencil sharpener

Abstract

The invention discloses a push type pencil sharpener. The push type pencil sharpener comprises a housing, a transmission mechanism, a driven mechanism, a cutting mechanism and a pencil inlet mechanism, wherein the housing comprises a first space and a second space which partly communicate with each other; an E-like second through hole is formed in the side surface of the housing, and the E-like second through hole comprises a vertical part and four horizontal parts which penetrate through the vertical part, so that four gear slots from top to bottom are formed; the transmission mechanism comprises a push rod, a first gear plate, a barrel sleeve and a compression spring; the driven mechanism comprises a rotary shaft, a second gear set and a fifth gear plate; the cutting mechanism comprises a fixed rod, a cutter holder and a milling cutter; the pencil inlet mechanism comprises a first part, a second part, an elastic element and a sixth gear plate. According to the push type pencil sharpener disclosed by the invention, energy can be stored through the compression spring, and the push rod drives the first gear plate to rotate by utilizing counter-acting force of the compression spring, so that the driven mechanism is further driven to rotate to drive the pencil inlet mechanism to rotate, and a pencil can be driven by the rotation of the pencil inlet mechanism to rotate relative to the cutting mechanism, so that the cutting work is completed, and therefore, the push type pencil sharpener has the advantages of being environmentally-friendly, energy-saving and quick.

Description

technical field [0001] The invention relates to a pencil sharpener. More particularly, the present invention relates to push-to-action pencil sharpeners. Background technique [0002] Pencils are tools for writing and note-taking purposes, and have accompanied the general public through many years. According to different uses of pencils, the requirements for the material of pencils are different. Different, for example, for softer wood, the cutting force requirement is lower, and for stronger wood, the required cutting force is greater. The pencil sharpeners currently used for sharpening pencils are divided into hand-operated and electric. The hand-operated pencil sharpener generally drives the cutting mechanism to rotate around the pencil by operating the manual handle, and finally completes the cutting work of the pencil. In the whole process, Although the cutting force can be controlled artificially to complete the cutting of different pencils, the user must rotate the ...

Problems solved by technology

The pencil sharpeners currently used for sharpening pencils are divided into hand-operated and electric. The hand-operated pencil sharpener generally drives the cutting mechanism to rotate around the pencil by operating the manual handle, and finally completes the cutting work of the pencil. In the whole process, Although the cutting force can be controlled artificially to complete the cutting of different pencils, the user must rotate the handle continuously. Once it stops, the cutting mechanism will stop cutting, which is time-consuming and labor-intensive; electric pencil sharpeners need motors to drive the tool to cut. Driven by it, it can continue to cut and save labor. However, the existing electromotive force pencil sharpener consumes electricity and is not environmentally friendly, and the cutting force cannot be adjusted. Long-term use will damage the cutting edge, reduce the service life of the cutting mechanism, and cannot meet different types of pencils. cutting
