A kind of burnisher chi
Technical field
The invention belongs to drawing instrument technical field, is related to a kind of burnisher chi.
Background technology
Ruler is most commonly used hand drawing tool, particularly ruler, and existing ruler simple structure only includes chi more
Body and scale, the side wall after setting-out can often be stained with pen oil or lead powder, and the attachable mechanical stage period of the day from 11 p.m. to 1 a.m becomes easily infected by paper, affects paper
Cleaning is attractive in appearance with image, and is also also easy to produce grunge pollution paper after pen is rubbed with paper.
The content of the invention
The purpose of the present invention is for the above-mentioned problems in the prior art, there is provided a kind of to prevent on pen or on chi
The burnisher chi of grunge pollution paper.
The purpose of the present invention can be realized by following technical proposal:A kind of burnisher chi, including chi body, its feature exist
In:Offer bar hole, and one end closing on chi body length direction of described bar hole in the middle part of chi body along its length, it is another
End opening, described bar hole are respectively equipped with chute along the both sides hole wall in chi body length direction, also identical including two shapes
Shifting block, described shifting block is provided with the slide block coordinated with chute, and described slide block is located in chute and can make shifting block along bar
Shape hole length direction is slided, and described shifting block is respectively arranged at two ends with oil suction cotton-wool, described chi body edge along chi body length direction
The both sides edge and bar hole edge of length direction is equipped with graduation mark, and described chi body cross section is curved, and described is transversal
Face is vertical with chi body length direction, and chi body top surface and chi body bottom surface are arcwall face, and chi body thickness all same everywhere.
Two shifting blocks, during use, are first moved to the two ends of straight length to be painted, nib is penetrated in bar hole and profit
Mapped with graduation mark, after drawing is finished, while removal, nib can touch oil suction cotton-wool, by oil suction cotton-wool
Oil stain in cleaning nib can prevent grunge pollution paper.
Therefore prevent bar hole from touching paper, you can to prevent the grunge pollution paper on chi body.
In a kind of above-mentioned burnisher chi, described chi body has extension in one end that bar hole is closed, and extends
Portion's top surface and chi body either flush, extension bottom surface is provided with groove, and described groove and is provided with pencil sharpener.
In a kind of above-mentioned burnisher chi, described chi body bottom surface is provided with bar-shaped trough along chi body length direction, described
The embedded pencil of bar-shaped trough interior energy.
Therefore both there is the function of placing pencil, can have been sharpened a pencil using pencil sharpener again, be served many purposes.
In a kind of above-mentioned burnisher chi, described chute and slide block section are in dovetail channel-shaped and dovetails respectively
Shape.
Compared with prior art, the invention has the advantages that:
Two shifting blocks, during use, are first moved to the two ends of straight length to be painted, nib is penetrated in bar hole and profit
Mapped with graduation mark, after drawing is finished, while removal, nib can touch oil suction cotton-wool, by oil suction cotton-wool
Oil stain in cleaning nib can prevent grunge pollution paper.

Specific embodiment
The following is the specific embodiment of the present invention and combine accompanying drawing, technical scheme is further described,
But the present invention is not limited to these embodiments.
As Figure 1-4, a kind of burnisher chi of the invention, including chi body 1, is offered in the middle part of chi body 1 along its length
Bar hole 11, and bar hole 11 one end closing, another end opening on 1 length direction of chi body, bar hole 11 is along 1 length side of chi body
To both sides hole wall on be respectively equipped with chute 12, also including two shape identical shifting blocks 2, shifting block 2 is provided with is matched somebody with somebody with chute 12
The slide block 21 of conjunction, slide block 21 are located in chute 12 and shifting block 2 can be made to slide along 11 length direction of bar hole, and shifting block 2 is along chi body 1
Length direction is respectively arranged at two ends with oil suction cotton-wool 22, and the both sides edge along its length of chi body 1 and 11 edge of bar hole are all provided with
There is graduation mark 17,1 cross section of chi body is curved, cross section is vertical with 1 length direction of chi body, 1 top surface of chi body and 1 bottom surface of chi body are equal
For arcwall face, and the thickness all same everywhere of chi body 1.
Further, chi body 1 has extension 13 in one end that bar hole 11 is closed, and 13 top surface of extension is pushed up with chi body 1
Face is concordant, and 13 bottom surface of extension is provided with groove 14, and groove 14 and is provided with pencil sharpener 15.1 bottom surface of chi body is along 1 length direction of chi body
Bar-shaped trough 16 is provided with, 16 interior energy of bar-shaped trough is embedded in pencil.Chute 12 and 21 section of slide block are in that dovetail channel-shaped and dovetail are block respectively.
Two shifting blocks 2, during use, are first moved to the two ends of straight length to be painted, nib is penetrated in bar hole 11 simultaneously
Mapped using graduation mark 17, after drawing is finished, while removal, nib can touch oil suction cotton-wool 22, by inhaling
Oily cotton-wool 22 prevents grunge pollution paper by cleaning the oil stain in nib.
Specific embodiment described herein is only explanation for example spiritual to the present invention.Technology neck belonging to of the invention
The technical staff in domain can be made various modifications or supplement or replaced using similar mode to described specific embodiment
Generation, but without departing from the spiritual of the present invention or surmount scope defined in appended claims.
Although more having used chi body 1, bar hole 11, chute 12, extension 13, groove 14, pencil sharpener 15, bar herein
The terms such as shape groove 16, graduation mark 17, shifting block 2, slide block 21, oil suction cotton-wool 22, but it is not precluded from the possibility using other terms.
It is used for the purpose of more easily describing and explaining the essence of the present invention using these terms;It is construed as any additional
Restriction be all contrary with spirit of the invention.
