Abstract
The utility model discloses a pencil sharpener with automatic core grinding function which belongs to rotary grinding pencil sharpener. The utility model is characterized in that a short knife blade and a case is integrated with a retaining screw; the shell is provided with a guide hole, thereby, the cutting part of the pencil sharpener with automatic core grinding function is formed; the rotation gear of the pencil sharpener with automatic core grinding function is composed of batteries, a micro machine and a switch; the output shaft of the micro machine is provided with a carborundum disc; the shell is provided with the guide hole, a press cover and a cover casing. The cutting part cuts the wood part of a pencil only and the pencil lead is kept in the original state; the pencil lead can be ground into the shapes of round, square or tabular automatically by the carborundum disc driven by the rotation gear; the length of the sharpened pencil lead can be controlled when the wood is being cut. The utility model, which has the advantages of convenient operation, time saving, and labor saving, can be widely used in various pencils for wood cutting and automatic pencil lead grinding.
Description
The utility model grinds plumbous pencil sharpener automatically and belongs to volume mill pencil-knife.
Pencil sharpener is that body and blade are formed in prior art, it is tapered at body to insert pen container, cut wood chip and lead for retractable pencil when cutting lead simultaneously, its shortcoming is the easily broken lead of cutting, plumbous length is wayward, and the scope of application is narrow, because wooden hardness is different with plumbous hardness, the dark lead of wooden penetration of a cutting tool is often because of stressed too big, and the lead that fractures easily.In addition, the fixing plumbous length of blade, pen and lead for retractable pencil concentricity are poor, all are to cause disconnected plumbous reason.
The utility model grinds the purpose of plumbous pencil sharpener automatically, is to overcome above-mentioned shortcoming and design the plumbous pencil sharpener of a kind of automatic mill.It is to be made of screw, shortened cutting blade, sand sheet, micromachine, gland, case, housing, battery.It adopts pilot hole to keep pencil and lead for retractable pencil concentricity height, shortened cutting blade cutting wood chip, and mill is plumbous automatically.
The utility model grinds plumbous pencil sharpener automatically and takes following scheme to realize.It is to be fixed in by screw by shortened cutting blade to constitute cutting tip on the housing, constitutes rotating mechanism by battery and micromachine and switch, and the sand sheet is set on the micromachine output shaft, and pilot hole and gland and case are set on the housing.Cutting tip only cuts wood chip, and rotating mechanism drives the sand sheet, and it is plumbous to be used for mill, according to demand lead is worn into circle, square, flat etc., can control plumbous length during the cutting wood chip, and is easy to use, time saving and energy saving, is widely used in the cutting wood chip of pencil and mill is plumbous automatically.
The utility model grinds the effect of plumbous pencil sharpener automatically, is that mill is plumbous automatically.The plumbous length of control cutting is as required worn into lead shapes such as circle, square, flat, and the utility model is simple in structure, manually cuts wood chip, and electronic mill lead is easy to use, and is time saving and energy saving, is widely used in the cutting of various pencils and mill is plumbous automatically.
The utility model grinds plumbous pencil sharpener automatically and will be further described in conjunction with the accompanying drawings.
