Two-hole pencil sharpener

Abstract

The invention provides a two-hole pencil sharpener which comprises a knife rest. The knife rest is provided with a knife. The knife is installed on the knife rest through a knife shaft. The knife is fixedly connected with a transmission gear. The knife rest is provided with two pencil inserting holes with different hole diameter sizes, and pencil sharpening holes are formed in the hole walls of the two pencil inserting holes separately. The transmission gear is provided with different diameter parts used for correspondingly cutting pencil tips of different lengths. According to the two-hole pencil sharpener, the two pencil sharpening holes with the different hole diameter sizes are formed in the knife rest, and the cutting requirements of pencils with different thicknesses can be met.

Description

Technical field [0001] The invention relates to a pencil sharpener. Background technique [0002] The electric pencil sharpener is a stationery driven by a motor and transmitted to the hob to cut the tip of the pencil. The hob has a certain inclination angle in the pencil sharpener, so that one end of the pencil can be cut to expose a certain length and have a taper. Of usable pencil nibs. The electric pencil sharpener in the prior art usually has an insertion opening for cutting the pencil on the top cover, a hob is arranged under the cover, and a pencil cutting opening is arranged on one side of the hob. After the pencil is inserted into the pencil sharpener, the motor is started. The hob is driven to rotate to cut the tip of the pencil, and the waste generated by the cutting falls into the cover. The cover is provided with an opening, and the waste can be poured out from the opening after the cutting is completed. [0003] At present, electric pencil sharpeners usually need to...

AI Technical Summary

Problems solved by technology

[0006] The above-mentioned patents solve the problem of cutting pencil nibs with different taper angles to a certain extent. However, in actual use, not only the length of the pencil nib and the taper angle are required, but also the thickness and length of the pencil shaft. There are often many pencils with different thicknesses and lengths; in addition, the above-mentioned patent adjusts the length and taper angle of the pencil tip to be cut by setting cutting holes with different lengths and sizes on the knife holder, and does not change the cutting time. The angle change of the tool, in fact, the most important thing in cutting different taper angle nibs is to change the cutting angle. Only the shape of the cutting hole is used to limit the shape of the pencil to be cut. In fact, the trajectory of the cutting itself is not really changed. It is a kind of The practice of giving up the basics and looking for the last, in fact, may cause greater wear to the tool post during the cutting process, and the cutting effect is not good.
