Description
Technical field
The present invention relates to a kind of pencil sharpener, more particularly to a kind of new-type pencil sharpener for being easy to carry out lead for retractable pencil grinding action,
Belong to novel office table separation.
Background technology
Pencil sharpener is the instrument to sharpen a pencil, and when the 17th century, people are simply sharpened a pencil with knife.With entering for society
Step, to 19 beginnings of the century, people not only need to use more pencils, and the spent time that sharpens a pencil there has also been higher
Requirement, the pencil sharpener of theory of mechanics is exactly to arise at the historic moment in such a case.1828, Frenchman invented in the world first
Pencil sharpener, in ensuing several centuries, pencil sharpener has been developing progressively well known appearance.
Student is when coating answering card, it is desirable to uses Pencil with 2B hardness.Because the answer bar on answering card is rectangle, therefore,
The lead for retractable pencil of pencil is preferably ground as cuboid-type or rectangular pyramid bench-type, to improve coating efficiency and quality.However, use common volume
The lead for retractable pencil that graver is cut out is excessively sharp, easily scratches answering card during coating, and lead for retractable pencil easily snaps off, and therefore, the lead for retractable pencil cut out is also needed into one
The grinding of step.The existing grinding processing method to lead for retractable pencil is nothing more than Tool in Cutting or manual grinding is used, i.e., time-consuming to take
Power, and lead for retractable pencil frangibility, reduce the efficiency and quality to sharpen a pencil.
The content of the invention
For the demand, the invention provides a kind of new-type pencil sharpener, and the pencil sharpener structure design is unique, in its outrigger
Some lead for retractable pencil grinding positions are set on body surface face, by the way that the lead for retractable pencil of cuboid-type or rectangular pyramid bench-type can be made after sharpening for several times, with
Just student uses when coating answering card.
The present invention is a kind of new-type pencil sharpener, and the pencil sharpener includes outer frame body, inner frame body and blade, described inside and outside frame
Body is integrally formed by Shooting Technique, and blade is fixed on inner frame body using screw, and described outer frame body installs blade one non-
Some lead for retractable pencil grinding positions are set on the surface of side, and described lead for retractable pencil is ground position and is made up of flat surface grinding position and forming surface grinding position.
In a preferred embodiment of the present invention, described lead for retractable pencil grinding position surface bonding Brown Alundum sand grains, the corundum sand
The particle diameter of grain is about 50-60um.
In a preferred embodiment of the present invention, the length of described flat surface grinding position is about 2cm, and width is about 1cm.
In a preferred embodiment of the present invention, described forming surface grinding position is made up of two function digits, respectively four ribs
Frustum is ground position and cuboid grinding position.
In a preferred embodiment of the present invention, the anterior of described forming surface grinding position sets transition slot structure.
Present invention is disclosed a kind of new-type pencil sharpener, and the pencil sharpener structure design is unique, and preparation technology is easy, and cost is fitted
In, the lead for retractable pencil set up on its outer frame body surface is ground position, can pass through lead for retractable pencil and cuboid-type or rectangular pyramid are formed after sharpening for several times
Bench-type, easy to operate, efficiency high, it is convenient to be provided for student when coating answering card.
Brief description of the drawings
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description：
Fig. 1 is the structural representation of the new-type pencil sharpener of the embodiment of the present invention；
The mark of each part is as follows in accompanying drawing：1st, outer frame body, 2, inner frame body, 3, blade, 4, screw, 5, flat surface grinding position, 6, into
Profile grinding position, 7, lead-over groove.
Embodiment
Presently preferred embodiments of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
Fig. 1 is the structural representation of the new-type pencil sharpener of the embodiment of the present invention；The pencil sharpener includes outer frame body 1, the and of inner frame body 2
Blade 3, described inside and outside support body are integrally formed by Shooting Technique, and blade 3 is fixed on inner frame body 2 using screw 4, described
Outer frame body 1 some lead for retractable pencils grinding positions are set on the non-surface for installing the side of blade 3, described lead for retractable pencil is ground position by flat stone mill
Cut position 5 and forming surface grinding position 6 forms.
In the new-type pencil sharpener that the present invention refers to, lead for retractable pencil grinding position surface bonding Brown Alundum sand grains, the Brown Alundum sand grains
Particle diameter is about 50-60um；Used adhesive is acetal resin or epoxy resin when Brown Alundum sand grains solidifies, after bonding
Lead for retractable pencil grinding position there is good grinding performance, and anti-wear performance and service life protrude.
The length of flat surface grinding position 5 in above-mentioned lead for retractable pencil grinding position is about 2cm, and width is about 1cm, and the station is mainly used in
It is ground the end of lead for retractable pencil；Forming surface grinding position 6 is made up of two function digits, respectively tetragonous cone table grinding position and cuboid grinding
Position, the station are mainly used in being ground the surface of revolution of lead for retractable pencil；The anterior of forming surface grinding position 6 sets the structure of lead-over groove 7, and the structure is used
When preventing from being ground the lead for retractable pencil surface of revolution, the end of lead for retractable pencil is damaged.
Present invention is disclosed a kind of new-type pencil sharpener, it is characterized in：The pencil sharpener structure design is unique, preparation technology letter
Just, moderate cost, the lead for retractable pencil grinding position set up on its outer frame body surface, can make lead for retractable pencil by forming cuboid-type after sharpening for several times
Or rectangular pyramid bench-type, easy to operate, efficiency high, it is convenient to be provided for student when coating answering card.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
Those skilled in the art disclosed herein technical scope in, can without the change that creative work is expected or
Replace, should all be included within the scope of the present invention.Therefore, protection scope of the present invention should be limited with claims
Fixed protection domain is defined.
