Abstract

The utility model relates to a multifunction pencil sharpener which is suitable for sharpening pencils with various specifications, models and quality of various industries personnel at home and abroad. The utility model is composed of a knife bed, a knife blade and screws. Right and left rotary cutting holes and a planing hole are arranged on the knife bed, three edges of the knife blade are provided with cutting edges, and the surface of the knife blade is provided with file grooves. The utility model is capable of rotary cutting a pencil right and left, planing a pencil and grinding the pencil tip. The service life of the multifunction pencil sharpener is three times as much as the existing product, and the utility model is an ideal sharpener for cutting a pencil. The utility model has the advantages of advanced technology, reasonable structure and material saving. The multifunction pencil sharpener makes materials put to good use and takes precedence of the existing product. In addition, the utility model is capable of being produced through adopting equipment, materials, technology and condition of the existing product manufacturing.

Description

Multifunction pencil sharpener

A kind of multifunctional pencil sharpener of the usefulness that sharpens a pencil is applicable to that domestic and international every profession and trade personnel cut the pencil usefulness of all size, model, quality.

Existing pencil-knife can only sharpen a pencil to revolving (volume) by folk prescription, just can not work during greater than rated specification or non-garden shape, non-six prismatic pencils as pencil diameter; When the wood grain pencil that runs into the contrary short, bristly hair or beard of rotary cut direction, wood grain splitting etc.; In a word, the existing product function singleness, poor-performing, the scope of application is narrower, and the quality that sharpens a pencil is not very good yet.

The purpose of this utility model has provided a kind of multi-functional pencil-knife that is applicable to all size, model, shape and quality, it has not only kept the existing product function, and possessed the performance and the characteristics of carpenter's plane and file again, it can left-handedly sharpen a pencil, but dextrorotation sharpens a pencil again, can sharpen a pencil by planer again, can also grind tip of a pencil with the cut face on the blade.

The technology of the present invention advanced person, rational in infrastructure, light and handy material-saving, because blade three limits of pencil-knife are provided with cutting edge, its life-span is three times of existing product life-span, is fit to the pencil of all size model, but left and right sides rotary cut pencil, the pencil of also can planing, also can file multiple functions such as tip of a pencil, accomplish to make the best use of everything, be desirable sharpening a pencil cutter, be superior to existing product, adopt equipment, material, technology, the condition of making existing product to produce.

Be described in detail concrete structure of the present utility model and operational detail below in conjunction with accompanying drawing.
