Problems solved by technology

[0002] Pencil sharpeners that are commonly used now are more convenient to use, but due to the different diameters of pencil cores, it is easy to cause excessive cutting of pencils, so that most of the pencil cores are actually cut off rather than written, which is wasteful. Very large; because the cutting diameter of the pencil sharpener refill cannot be adjusted, there are limitations in use. For those professional pencils and pencils with thick refills, ordinary pencil sharpeners cannot meet the requirements, and special pencil sharpeners are needed, and this special pencil sharpener hard to find in the market

Embodiment 1

[0021] Such as figure 1 A shown method for adjusting the diameter of the cutting pencil tip is to set a movable baffle at the top end of the tapered sharpener hole of the pencil sharpener, and move along the tapered sharpener hole under the blade. Adjust the position of the baffle to change the walking distance of the pencil, and use the position of the moving baffle to adjust the diameter of the pencil sharpener for cutting the pencil tip. This method can change and adjust the cutting diameter of the pen tip and prevent excessive cutting of the thick-core pencil tip. It can not only cut pencils with ordinary refill diameters, but also achieve the effect of cutting pencils with large refill diameters without excessive cutting.

Embodiment 2

[0023] Such as figure 1 A method for adjusting the diameter of the pencil sharpener tip is shown. The initial position of the pencil sharpener baffle is at the apex of the conical sharpener hole. The distance traveled by the pencil is determined, and the cutting diameter of the pencil sharpener tip is determined. When it is necessary to change When cutting the diameter of the pencil sharpener tip, the baffle moves under the blade along the tapered sharpener hole to a specified position on the central axis of the conical sharpener hole. The cutting diameter of the pencil tip at this position is what we need to cut Pencil tip diameter. By adjusting the position of the baffle, you can get a thin pencil tip or a thicker pencil tip according to your needs. Using a pencil sharpener can meet our requirements for pencils of different thicknesses in different occasions, and bring us a sense of convenience. Come to great convenience. For example, when the examinee needs to scribble on...

Embodiment 3

[0025] Such as figure 1 A pencil sharpener that can adjust the diameter of the sharpening pencil tip as shown is mainly composed of a body, a tapered pencil sharpening hole, a blade and a screw for fixing the blade on the tapered pencil sharpening hole. The movable baffle is set, and the movable baffle is in the tapered pencil sharpener hole and moves along the tapered pencil sharpener hole. Baffle plate size is limited in the taper sharpener hole, and shape is not limited, and baffle plate can be plane, also can be curved surface, but the position of the apex end of pencil sharpener conical sharpener hole will be included in the baffle plate. The method of use is, because the movable baffle can be initially set without adjustment, and the movable baffle needs to be moved only when the cutting diameter of the pen tip needs to be changed, so the method of use is completely the same as that of an ordinary pencil sharpener, and can be used normally. When the cutting diameter of ...

Abstract

The invention provides a pencil sharpener capable of adjusting the pencil tip sharpening diameter and a method. The pencil sharpener comprises a pencil sharpener body, a sharpener blade, a tapered pencil sharpening hole and a screw, wherein the screw is used for fixing the sharpener blade on the tapered pencil sharpening hole of the pencil sharpener; and a movable baffle plate is arranged at the top end of the tapered pencil sharpening hole of the pencil sharpener, positioned in the tapered pencil sharpening hole, and moves along the tapered pencil sharpening hole. According to the method, the traveling distance of a pencil is changed and determined by utilizing changes in the position of the movable baffle plate, the pencil sharpening diameter of the small-hole end of the pencil sharpener is changed correspondingly, and then the pencil tip sharpening diameter of the pencil sharpener is adjusted. By adoption of the pencil sharpener and the method, not only a pencil with common pencil lead but also a pencil with large-diameter pen lead can be sharpened; the problems that pencils with different pencil lead diameters can only be sharpened by the same pencil sharpener, and that several pencils are excessively sharpened by a common pencil sharpener can be solved, thereby avoiding the resource waste; and meanwhile, the use object range can be expanded to a group using special pencils, and more convenience can be brought to people in life and study.

Description

technical field [0001] The invention belongs to the field of stationery, in particular to stationery for pencil sharpeners. Background technique [0002] Pencil sharpeners that are commonly used now are more convenient to use, but due to the different diameters of pencil cores, it is easy to cause excessive cutting of pencils, so that most of the pencil cores are actually cut off rather than written, which is wasteful. Very large; because the cutting diameter of the pencil sharpener refill cannot be adjusted, there are limitations in use. For those professional pencils and pencils with thick refills, ordinary pencil sharpeners cannot meet the requirements, and special pencil sharpeners are needed, and this special pencil sharpener It is hard to find in the market. Contents of the invention [0003] The invention provides a pencil sharpener capable of adjusting the diameter of the cutting pencil tip and a method thereof. A movable baffle is set at the apex of the pencil sh...
