Abstract
The utility model relates to a pencil sharpener capable of effectively cutting a pencil head into a flat shape. The pencil sharpener comprises opening and closing grinding holes and a tightening device. The opening and closing grinding holes are grinding pencil lead holes or grinding slits capable of being opened and closed along with the thickness of a pencil lead, and the tightening device is an elastic part which exerts force on the grinding holes so that the grinding holes can generate tightening force. The pencil lead cut out of a pencil body cutting blade enters the opening and closing grinding holes. The grinding holes can be two opposite grinding heads, the grinding heads are installed in a horizontal sliding groove, the front of the inner side of each grinding head is provided with a V-shaped opening, the tightening device can comprise at least one grinding head pressure spring, is placed in the sliding groove and acts on the grinding heads, and pressure of the grinding head pressure spring can be adjusted through an adjusting screw. The pencil sharpener has the advantages of having a gradual change reducing process during penpoint cutting and being capable of quickly effectively cutting a pencil into the flat shape.
Description
Technical field
The utility model relates to a kind of device of sharpening pencil, specifically a kind ofly can fast and effectively pencil stub be cut into the pencil sharpener of flat.
Background technology
Now, the form of filling in machine-read card card is used among various examinations more and more, and uses flat nib pencil to be not only applicable to fill in machine-read card card, also can be used for mapping drawing etc. simultaneously.But most of pencil sharpener of nowadays selling on the market all cannot directly cut into flat Like by tip of a pencil.For this reason, occurred some designs, as Chinese patent, publication number is " CN 202138122 ", this design drives master gear by Propelling pencil with sharpener in cap, and then drive driven gear rotation, make blade cycles ground rotary cutting nib, but this design, only adapt to hexagon pencil, and the process that does not have 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 " CN 101973177 ", 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, the easy disconnected nib in top, is difficult to reach and cuts flat pen core object.
Summary of the invention
In order to address the above problem, the utility model provides a kind of can effectively be whittled into tip of a pencil the pencil sharpener of flat.
The technical solution adopted in the utility model 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 be with grinding reservoir hole or the seam of pencil-lead thickness folding, described to close tight device be to be applied on grinding hole, makes it to produce the elastic component that closes tight power.Described body bite is for only cutting the bite that a body partly exposes nib, described pencil sharpener shell is a box type, have a cavity volume inside to pack a body bite into, a body bite can slide and reset under the effect of spring in front and back in this cavity volume, and the pen core of cutting 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 shell front portion, grinding hole comprises two relative grinding machine heads, grinding machine head packs horizontal concrete chute into, 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.In horizontal concrete chute end, can increase screw, be equipped with adjusting screw(rod), grinding machine head stage clip pressure can regulate 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 of cutting 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) and presses described stage clip for pushing up, and regulates the pressure to grinding machine head.Adjusting screw(rod) can pass through 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, and above-mentioned grinding machine head inner side can fixedly mount guide post, and guide post coordinates with through hole or the catch pipe of self adaptation part, for the orientation of sliding.
The course of work of the present utility model is: first with a body bite volume, cut out pen core, 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, thereby can realize gradual change, cuts down process.Adjustablely close tight device and also can regulate the grinding force in grinding hole, make 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, thereby make pen core be easy to insert grinding hole through " V " shape opening, and make grinding hole align all the time pen core, and the grinding force that pen core both sides are subject to is equated, guaranteed the ablation that nib both sides obtain being equal to.
The beneficial effects of the utility model have gradual change to cut down process when cutting nib, can fast and effeciently pencil cutting be become to flat.
