Description
Technical field
The present invention relates to a kind of device of sharpening pencil, specifically a kind of pencil sharpener that fast and effectively pencil stub can be cut into flat.
Background technology
Now, the form of filling in machine-read card card is used among various examination more and more, and uses flat tip pencil to be not only applicable to fill in machine-read card card, also can be used for mapping drawing etc. simultaneously.But tip of a pencil all cannot directly be cut into flat Like by nowadays sold on the market most of pencil sharpener.For this reason, occurred that some design, as Chinese patent, publication number is " CN202138122 ", this design drives master gear by Propelling pencil with sharpener in cap, and then drive driven gear to rotate, make blade cycles ground rotary cutting nib, but this design, only adapt to hexagon pencil, and the process not having gradual change to cut down when cutting nib, be easy to scrape disconnected pen core, and complex structure.Publication number is the Chinese patent of " CN101973177 ", its method is, after cutting out pen core by a common volume method, nib is directly headed into the Flat tip edge of a knife, it is a kind of extraordinary design concept, but this mode does not have progressive cutting nib process equally, break nib on easy top, is difficult to reach cut flat pen core object.
Summary of the invention
In order to solve the problem, the invention provides a kind of pencil sharpener that effectively tip of a pencil can be whittled into flat.
The technical solution used in the present invention is: a kind of machinable becomes flat pencil sharpener, comprise shell, cavity volume, a body bite, folding grinding hole, close tight device, described folding grinding hole is one can with the grinding reservoir hole of pencil-lead thickness folding or seam, the tight device of described conjunction is applied on grinding hole, makes it to produce the elastic component closing tight power.Described body bite is that only a cutting body part exposes the bite of nib, described pencil sharpener shell is a cell type, have a cavity volume inside to load a body bite, a body bite also can reset under the action of the spring by slide anteroposterior in this cavity volume, and the pen core cut out is to entering folding grinding hole.
Above-mentioned folding grinding hole, close tight device and comprise horizontal concrete chute, grinding machine head, grinding machine head stage clip, described horizontal concrete chute is positioned at housing front, grinding hole comprises two relative grinding machine heads, grinding machine head loads horizontal concrete chute, the V-shaped opening of grinding machine head interior front, this opening is corresponding with the pen core outlet of a body bite.Close tight device and comprise at least one grinding machine head stage clip, it is placed in chute, and acts on grinding machine head.Can increase screw in horizontal concrete chute end, be equipped with adjusting screw(rod), grinding machine head stage clip pressure regulates by adjusting screw(rod).
Above-mentioned grinding machine head and stage clip also can be equipped with self adaptation part, and self adaptation part is that both ends are connected, the parts that can slide in horizontal concrete chute.Two relative grinding machine heads are placed in self adaptation part, and the pen core cut out, to entering grinding mouth, has at least a grinding machine head stage clip to be placed in self adaptation part, and acts on grinding machine head.
A screw also can be opened in one end of above-mentioned self adaptation part, and this screw is equipped with adjusting screw(rod) for pushing up the described stage clip of pressure, regulates the pressure to grinding machine head.Adjusting screw(rod) is by catch top pressure spring.
One end of not opening screw of above-mentioned self adaptation part can arrange a through hole, and above-mentioned catch one side can fixedly mount a pipe, can fixedly mount guide post inside above-mentioned grinding machine head, and guide post coordinates, for orientation of sliding with the through hole of self adaptation part or catch pipe.
The course of work of the present invention is: first cut out pen core with a body bite volume, and then promote and discharge pencil to make a body bite make front-rear reciprocation movement in its shell cavity volume, pen core inserts grinding hole simultaneously, due to folding grinding hole and the effect of closing tight device, the opening degree in grinding hole can change with nib grinding situation, thus can realize gradual change reduction process.The tight device of adjustable conjunction also can regulate the grinding force in grinding hole, makes it to obtain best ground effect.
Above-mentioned self adaptation part working method be: because self adaptation part can slide in shell front cross chute, thus make pen core be easy to insert grinding hole through " V " shape opening, and make grinding hole align pen core all the time, and the grinding force making pen core both sides be subject to is equal, ensure that nib both sides obtain the ablation be equal to.
Beneficial effect of the present invention has gradual change to cut down process when cutting nib, fast and effeciently pencil cutting can be become flat.

Detailed description of the invention
The technical solution used in the present invention is: a kind of machinable becomes flat pencil sharpener, described body bite 2 is that only a cutting body part exposes the bite of nib, described pencil sharpener shell 1 is a cell type, a cavity volume 1a inside is had to load a body bite 2, body bite 2 can in this cavity volume slide anteroposterior resetting under the effect of spring 3, housing front has a horizontal concrete chute 1b, described self adaptation part 6 is placed in chute, self adaptation part 6 connects for end one 6b, end two 6c are connected plate 6d, the parts that can slide in horizontal concrete chute 1b.Self adaptation part 6 is built with two relatively described grinding machine heads 4, the V-shaped opening of grinding machine head 4 interior front, this opening is corresponding with the pen core outlet of a body bite 2, and have two stage clips 5 to be placed in self adaptation part 6, one end of two stage clips 5 is respectively with grinding machine head 4 contact outside.There is a screw one end of self adaptation part 6, and this screw is equipped with described adjusting screw(rod) 7 for pushing up the other end of pressing described stage clip 5, regulates the pressure to grinding machine head 4.
The other end of self adaptation part 6 arranges a through hole 6a.
Above-mentioned adjusting screw(rod) 7 pushes up pressure stage clip 5 by above-mentioned catch 8, catch 8 one side fixed installation one catch pipe 8a.
Fixedly mount above-mentioned guide post 4a inside above-mentioned grinding machine head 4, guide post 4a coordinates, for orientation of sliding with the through hole 6a of above-mentioned self adaptation part 6 or catch pipe 8a.
The course of work of the present embodiment is: first cut out pen core with body bite 2 volume, and then promote pencil and make a body bite 2 make front-rear reciprocation movement in its shell cavity volume 1a, pen core inserts in grinding machine head 4 under the guide effect of cutting fast " V " shape opening simultaneously, owing to there being the effect of grinding machine head stage clip 5, opening degree between two grinding machine heads 4 can change with nib grinding situation, thus can realize gradual change reduction process.Pressure between two grinding machine heads 4 also regulates by adjusting screw(rod) 7.Because self adaptation part 6 can slide in shell 1 front cross chute 1b, thus make the grinding between two grinding machine heads 4 stitch centering all the time, and the grinding force that nib both sides are subject to is equal, ensure that nib both sides obtain the ablation be equal to.
