Knife rest of pencil sharpener

Abstract

The invention discloses a knife rest of the pencil sharpener. The knife rest comprises a knife rest base, a pencil containing bin assembly and a hob assembly, wherein a pencil inserting hole is formedin a front baffle of the knife rest base, the pen containing bin assembly is formed by connecting a pen containing bin block, a pushing support plate and a pressing block, two conical pen holes withopenings in the top faces and different sizes are formed in the two sides of the upper portion of the pen containing bin block, the hob assembly is formed by connecting a hob, a hob shaft, a positioning hinge sleeve and a transmission gear, the pen containing bin assembly and the hob assembly are movably connected together in an adjustable mode, the pen containing bin assembly and the hob assemblyare vertically and movably fixed to the knife rest base, and one of a large conical pen hole and a small conical pen hole formed in the pen containing bin block can be aligned to the pen inserting hole to be positioned by adjusting an adjusting shaft arranged on the pen containing bin block, the pencil sharpener connected to the knife rest can selectively sharpen two pencils with different sizesof conical angle nibs suitable for common writing requirement pencils and sketch using requirement sketch pencils, and the purpose that one pencil sharpener has two purposes is achieved.

Description

technical field [0001] The invention relates to the technical field of stationery, in particular to a knife holder of a pencil sharpener. Background technique [0002] Pencil sharpeners are stationery for people's daily study and office work. There are many styles of pencil sharpeners on the market. At present, the pencil sharpeners equipped with hob-type tool holders are easy to use, short in stable time, and good in cutting quality. , and is deeply loved by users. There are hand-operated and electric pencil sharpeners of this kind, but regardless of the hand-operated or electric pencil sharpeners, the core components of their pencil sharpeners, the main structure of the tool holder with hob, are roughly the same. structure see Figure 15-1 , 15-2 , including knife rest seat 1', hob 2', hob shaft 3', and transmission gear 4', one end of said knife rest seat 1' is provided with a pen holder 11' for pencil insertion, and a pen holder 11' It is a conical structure, and ther...

AI Technical Summary

Problems solved by technology

Although the above-mentioned pencil sharpener has many advantages, due to the conical shape of the pen chamber in its knife holder structure, the conicity of the pen chamber is fixed, and the hob that cooperates with the cutting long hole on the pen chamber is also fixedly connected to the knife holder seat. , so the angle of conicity of the planed pencil tapered head is fixed, and the length of the wooden cover rod and pen core of the pencil tapered head is also fixed correspondingly, which can only be suitable for pencil planing required by ordinary writing. For example, the sketch pen used for planing art sketches is not good, because the sketch pen is different from the pencil for ordinary writing, and the pen core is required to be thin, sharp and long, so that it can withstand consumption. The rod is more than 1.5cm, so it is generally cut by hand

There are also pencil sharpeners specially used for sketch pens on the market. If users need a pencil sharpener to plan ordinary writing pencils and sketch pens, they can only be equipped with two different pencil sharpeners at the same time, which is a waste of resources. It is inconvenient to use

[0003] In response to the above problems, an electric pencil sharpener suitable for planing two kinds of conical heads has also been introduced on the market. Two parallel cones with different cone angles for pencil insertion are arranged at one end of the built-in knife holder. The pen chamber and the hob are connected between the two pen chambers, among which the conical shape of the pen chamber with a large cone angle is cut and formed. The tapered head of the formed pencil has a small conicity and a long lead length. However, it can be seen from its structure that the hob and the main body of the tool holder are fixedly connected with the existing product. The difference is that the two offset In order to ensure that the conical shape of the pen holder is concentric with the pen insertion hole after left-right conversion, the taper formed by the two and the hob is not much different, so the conical angle of the tapered pencil head planed by the two is not very different. Large, which also limits the length of the refill, this pencil sharpener still cannot fully meet the requirements of both ordinary writing and sketching pencils and sketches.
