adjustable pencil sharpener

Abstract

The invention discloses a gear-adjustable pencil sharpener. The gear-adjustable pencil sharpener comprises a shell, a driving mechanism, a driven mechanism, a cutting mechanism, a pencil feeding mechanism and a pencil shaving collecting box. The shell comprises a first space and a second space which are partially communicated with each other, a second through hole in a shape similar to an E is formed in the side surface of the shell and comprises a vertical part and four horizontal parts which are all communicated with the vertical part, and four gear slots are formed from top to bottom. The driving mechanism comprises a pressing rod, a first gear set, a tube sleeve and a compression spring. The driven mechanism comprises a rotary shaft, a fixing rod, a fourth gear plate, a first bevel gear and a second bevel gear. The cutting mechanism comprises a cutter rest and a milling cutter. The pencil feeding mechanism comprises a first part, a second part and an elastic element. The pencil shaving collecting box is detachably disposed on the lower portion of the second space. By means of the gear-adjustable pencil sharpener, energy can be stored through the compression spring, the cutting mechanism is driven to rotate around a pencil through the counter-acting force of the compression spring, and therefore the cutting work is finished. The gear-adjustable pencil sharpener has the advantages of being environmentally friendly, capable of saving energy and fast.

Description

technical field [0001] The invention relates to a pencil sharpener. More specifically, the present invention relates to a pencil sharpener with adjustable stops. 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 rot...

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 the needs of different types. cutting of pencil
