The utility model is characterized in that the pencil sharpener frame is internally fixed with the pencil sharpener blade and the sharp knife, the blade of the sharp knife has a cutting on the periphery of the pencil, the fixing ring is sleeved at a knife mark on the periphery of the pencil and is fixed by the lock knob, the front end of the pencil is inserted into the interior of the pencil sharpener frame, and the outer surface of the pencil sharpener frame is the entire pattern.
Description
(1) technical field:
The utility model relates to the myopia prevention pencil-knife, divides the technical field that belongs to pencil or leads sharpening device group by International Patent Classification (IPC) (IPC).
(2) background technology:
At present, the technology about pencil or leads sharpening device group existing and that once had was all done very fruitful effort to the needs of myopia prevention pencil-knife, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1996 by Fu Yi, Granted publication is that CN2224740Y China Patent No. (ZL) is: ZL95245012.7 number utility model patent title is the utility model patent of " Two-purpose pencil cutter ", the technical scheme that is adopted, technical elements in pencil or leads sharpening device group is a routine of great value invention, and it has solved the dual-purpose technical problem of pencil-knife effectively.But still have some deficits, it also is difficult to solve myopia prevention, technical problem attractive in appearance.
(3) summary of the invention:
The purpose of this utility model is to provide a kind of myopia prevention pencil-knife.To solve myopia prevention, technical problem attractive in appearance.
The new technical scheme that above-mentioned technical problem to be solved in the utility model adopted is: myopia prevention pencil-knife of the present utility model mainly is made of pencil knife block, pencil-knife blade, pencil, sharp knife, pattern, retainer ring, fixing button.
In shape, structure and combination thereof, the total essential features of myopia prevention pencil-knife of the present utility model and immediate prior art is: the front end of pencil is inserted in the blade place of pencil-knife blade, the overall fixed of pencil-knife blade is installed in the inside of pencil knife block, be combined into the triangular shaped combining structure of rectangle band, function has been the effect that sharpens a pencil.In shape, structure and combination thereof, the myopia prevention pencil-knife of the present utility model technical characterictic different with immediate prior art is: the internal fixation of pencil knife block is installed pencil-knife blade and sharp knife, the blade cutting of sharp knife is at the cylindrical of pencil, with the tool marks place of Fixing shrink ring in the pencil periphery, and fix with fixing button, be combined into the combining structure of inverted T-shaped shape, function has been myopic-preventing effect.The front end of pencil inserts the inside of pencil knife block, and the outer surface air brushing of pencil knife block goes out whole pattern, is combined into the combining structure of trapezoidal shape, and function has been effect attractive in appearance.So just reached the myopia prevention of myopia prevention pencil-knife of the present utility model, purpose attractive in appearance.
The beneficial effect of the myopia prevention pencil-knife of utility model is that the utility model is to solve myopia prevention, and the technical scheme that technical problem adopted attractive in appearance has been compared two place's advantage and improvement with existing with the technology about pencil or leads sharpening device group that once had:
First, owing to designed the internal fixation of pencil knife block in the technical scheme of myopia prevention pencil-knife of the present utility model pencil-knife blade and sharp knife are installed, the blade cutting of sharp knife is at the cylindrical of pencil, with the tool marks place of Fixing shrink ring in the pencil periphery, and fix with fixing button, be combined into the combining structure of inverted T-shaped shape, so the myopic-preventing technical problem of easier solution.
Second, owing to designed the inside that the front end of pencil inserts the pencil knife block in the technical scheme of myopia prevention pencil-knife of the present utility model, the outer surface air brushing of pencil knife block goes out whole pattern, is combined into the combining structure of trapezoidal shape, so easier solution technical problem attractive in appearance.
