Present invention is disclosed a kind of Multifunction pencil sharpener, this pencil sharpener structure design is unique, and the nib after the system of cutting can be carried out effective passivation by the blunt head unit of pen core set up on knife rest and outer frame body in it, so that student uses when applying answering card; Meanwhile, the blunt head unit of this pen core is rational in infrastructure, it may also be useful to convenient, effectively improves the practicality of pencil sharpener.
Description
Technical field
The present invention relates to a kind of pencil sharpener, particularly relate to a kind of Multifunction pencil sharpener being convenient to be carried out by nib passivation operation, belong to novel office table separation.
Background technology
Pencil sharpener is the instrument cutting pencil, and when the 17th century, people just cut pencil with cutter. Along with the progress of society, to 19 beginnings of the century, people not only need to use more pencil, and there has also been higher requirement to cutting the time that pencil spends, and the pencil sharpener of theory of machines is exactly arise at the historic moment in such a case. 1828, Frenchman invented first pencil sharpener in the world, and in ensuing several centuries, pencil sharpener is developed into the appearance known by people gradually.
Student is when applying answering card, it is desired to use Pencil with 2B hardness. Owing to the answer bar on answering card is rectangle, therefore, the nib of pencil is preferably blunt head, to improve coating efficiency and quality. But, it may also be useful to the nib that common pencil sharpener cuts out is excessively sharp, easily scratches answering card during coating, and nib easily fractures, and therefore, the pen core cut out needs to carry out passivation by the mode of hand grinding. Hand grinding is consuming time and pencil lead storing frangibility, reduces the efficiency and quality of cutting pencil.
Summary of the invention
For above-mentioned demand, the present invention provides a kind of Multifunction pencil sharpener, and this pencil sharpener structure design is unique, sets up a blunt head unit of pen core within it on knife rest and outer frame body, shaping nib can be carried out effective passivation by this device, so that student uses when applying answering card.
The present invention is a kind of Multifunction pencil sharpener, this pencil sharpener comprises outer frame body, interior knife rest and blade, described outer frame body and interior knife rest are one-body molded by Shooting Technique, described interior knife rest is made up of left knife rest and right knife rest, described blade adopts screw to be connected on left knife rest, arranging the blunt head unit of pen core on the outer frame body of described right knife rest and corresponding side thereof, the blunt head unit of this pen core is primarily of taper hole, cutter knife, elastic button and knockout passage composition.
In a preferred embodiment of the present invention, described taper hole is arranged on right knife rest, and Qi Ding footpath is about 4.5mm, and footpath, the end is about 2mm, and the degree of depth is about 5mm.
In a preferred embodiment of the present invention, described cutter knife is erected at the positive right side of taper hole cone bottom, for cutting off the plumbous core stretched out from taper hole cone bottom.
In a preferred embodiment of the present invention, described cutter knife is by elastic button control, it may be achieved horizontal reciprocating moves, and combined stroke are about 5mm.
In a preferred embodiment of the present invention, described knockout channel setting is in the positive bottom of taper hole, and its diameter is about 2mm.
In a preferred embodiment of the present invention, described knockout passage is connected with taper hole, and runs through whole right knife rest from top to bottom.
Present invention is disclosed a kind of Multifunction pencil sharpener, this pencil sharpener structure design is unique, and the nib after the system of cutting can be carried out effective passivation by the blunt head unit of pen core set up on knife rest and outer frame body in it, so that student uses when applying answering card; Meanwhile, the blunt head unit of this pen core is rational in infrastructure, it may also be useful to convenient, effectively improves the practicality of pencil sharpener.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of embodiment of the present invention Multifunction pencil sharpener;
In accompanying drawing, the mark of each parts is as follows: 1, outer frame body, and 2, interior knife rest, 3, blade, 4, left knife rest, 5, right knife rest, 6, screw, 7, taper hole, 8, cutter knife, 9, elastic button, 10, knockout passage.
Embodiment
Below in conjunction with accompanying drawing, the better embodiment of the present invention is described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made more explicit defining.
Fig. 1 is the structural representation of embodiment of the present invention Multifunction pencil sharpener; This pencil sharpener comprises outer frame body 1, interior knife rest 2 and blade 3, described outer frame body 1 is one-body molded by Shooting Technique with interior knife rest 2, described interior knife rest 2 is made up of left knife rest 4 and right knife rest 5, described blade 3 adopts screw 6 to be connected on left knife rest 4, arranging the blunt head unit of pen core on the outer frame body 1 of described right knife rest 5 and corresponding side thereof, the blunt head unit of this pen core is primarily of taper hole 7, cutter knife 8, elastic button 9 and knockout path 10 composition.
In the Multifunction pencil sharpener that the present invention mentions, taper hole 7 is arranged on right knife rest 5, Qi Ding footpath is about 4.5mm, footpath, the end is about 2mm, the degree of depth is about 5mm, this structure design can make shaping nib fall into taper hole 7 structure completely, and nib has satisfactory stability and positioning precision in taper hole 7, effectively raises the quality of nib passivation operation.
Above-mentioned cutter knife 8 is erected at the positive right side that taper hole 7 bores bottom, the plumbous core that this cutter is bored bottom for cutting off stretch out from taper hole 7; Cutter knife 8 is controlled by elastic button 9, it may be achieved horizontal reciprocating moves, and combined stroke are about 5mm; When pressing elastic button 9, the plumbous core of cutter knife 8 transversely cutting, when rebound elastic button 9 time, cutter knife 8 auto-returned original position.
Knockout path 10 is arranged on the positive bottom of taper hole 7, and its diameter is about 2mm, and knockout path 10 is connected with taper hole 7, and runs through whole right knife rest 5 from top to bottom; After completing nib passivation operation, the plumbous core of cut-out can drop in knockout path 10, so that the carrying out smoothly of nib passivation operation next time.
Present invention is disclosed a kind of Multifunction pencil sharpener, be characterized in: this pencil sharpener structure design is unique, the nib after the system of cutting can be carried out effective passivation by the blunt head unit of pen core set up on knife rest and outer frame body in it, so that student uses when applying answering card; Meanwhile, the blunt head unit of this pen core is rational in infrastructure, it may also be useful to convenient, effectively improves the practicality of pencil sharpener.
The above; it is only the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the present invention; the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention. Therefore, protection scope of the present invention should be as the criterion with the protection domain that claim book limits.
