Further, the circular arc mode of described 1-50 mm dia is provided with 45 and differs successively the semicircle hollow slots wide at the top and narrow at the bottom of 1 millimeter and the semi arch pattern of 5 drawing board gabarits, and it is one group by be often separated by 5 circular arcs of 10 millimeters of diameter, diameter is poor to be equaled two groups of circular arcs of 5 and relatively puts, one group that diameter is larger is placed on outer ring, one group that diameter is less is placed on inner lane, and order is distributed on drawing board successively, indicates the numerical value of 1-50 mm dia between two groups of relative circular arcs.
Further, the angle orientation pattern of described 0-360 ° is uniformly set on the isolation strip between hollow slots and hollow slots, and indicates the angle orientation numerical value of 0-360 °; Angle numerical value mark be spaced apart 10 °, on 180 ° are labeled in diameter maximum in every group of circular arc circular arc mode isolation strip with interior angle numerical value, the angle numerical value of 181 °-360 ° is labeled on the isolation strip of the circular arc mode that diameter takes second place.
Further, above described drawing board, the prevention breadth of center rubs on dirty protruding inverted conical platform lateral surface, between relative two adjacent anti-skidding positioning cap installing holes, has the nib inserting hole that diameter is greater than drawing pen nib diameter;
Further, described anti-skidding positioning cap installing hole is up-small and down-big bell mouth shape, described anti-skidding positioning cap is manufactured with flexible rubber, mounting structure and anti-skidding positioning cap installing hole match and the sphere protruding are arranged to in top and bottom, drawing board bottom surface is protruded after installing slightly in bottom, and behind its top of appropriate finger pressure, anti-skidding positioning cap bottom surface can be equal with drawing board bottom surface.
Accompanying drawing explanation
Fig. 1 is the quincunx drawing board structural representation of 1-50 mm dia circular arc;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view;

Fig. 4 is that the A-A of Fig. 3 is to cutaway view.
In figure: circular coordinate index aperture 1, semicircle coordinate index aperture 2, coordinate line 3, circular arc hollow slots 4, isolation strip 5, anti-skidding positioning cap installing hole 6, inverted conical platform 7, nib inserting hole 8, anti-skidding positioning cap 9.
The specific embodiment
By the description to embodiment below; to more contribute to public understanding the utility model; but the specific embodiment that applicant can't be provided is considered as the restriction to technical solutions of the utility model, any definition to parts or technical characterictic changes or overall structure is made to form and immaterial conversion all should be considered as the protection domain that utility model technical scheme is limited.
Preferred embodiment of the present utility model as Figure 1-Figure 4, the set anti-skidding positioning cap 9 of the quincunx drawing board of 1-50 mm dia circular arc through finger pressure Matching installation in anti-skidding positioning cap installing hole 6.The bottom surface that before using, drawing board is slightly protruded in the bottom surface of anti-skidding positioning cap 9, when the unspecified angle that the arbitrary circular arc within the scope of drawing 1-50 mm dia and mark are 0-360 ° is located, adjust after the relative bearing of drawing board and drawing, with finger, pin gently on the other hand the top of the anti-skidding positioning cap 9 of part, the operation of can charting while making anti-skidding positioning cap 9 bottom surfaces equal with drawing board bottom surface, after drawing, nib is penetrated to prevention breadth gently and rub the nib inserting hole 8 of dirty inverted conical platform 7 sides, at hand, under the common cooperation of nib, lift gently drawing board, make drawing board steadily depart from drawing breadth, can effectively avoid not dry ink marks to rub dirt, affect drawing effect, by circular arc hollow slots 4, can draw out quickly and accurately the arbitrary circular arc within the scope of 1-50 mm dia, according to the angle orientation numerical value marking in isolation strip 5 and by the angle numerical value of mark on the circular coordinate index aperture 1 of various positions, semicircle coordinate index aperture 2, circular arc hollow slots 4 and isolation strip 5, can disposablely fast, accurately, clearly draw out the unspecified angle within the scope of 0-360 °, by the circular coordinate index aperture 1 on coordinate line 3 and semicircle coordinate index aperture 2, can draw coordinate and greatly improve its accuracy equally.
