The specific embodiment

In order to make those skilled in the art person understand the utility model scheme better, and make the above-mentioned purpose of the utility model, feature and advantage can be more obviously understandable, below in conjunction with accompanying drawing and embodiment the utility model done further detailed explanation.

Embodiment: shown in Fig. 1-8, the shaft of a writing brush 2 lower ends are provided with shaft of a writing brush head 1, the shaft of a writing brush head 1 outer cap for brush 4 that adds; Shaft of a writing brush head 1 and the shaft of a writing brush 2 are connected through screw, and the pen cores in the shaft of a writing brush 2 can be one of three kinds of patterns: one of which is propelling pencil, and is as shown in Figure 6; There is handle 10 upper end of propelling pencil pen core 11; The bottom is provided with and presses control core apparatus 12, during handle 10, can impel pencil-lead wherein overhanging gradually instantly.It two is ball pen, and is as shown in Figure 5, is provided with pen core in the shaft of a writing brush 2, presses control core apparatus and press button 8, and interior three coloured pencils of installing, each pen core all have own pressing to control core apparatus and press button 8, and press button 8 can slide up and down in cylindrical void 9, and cylindrical void 9 is opened on the shaft of a writing brush 2.It three is a gel ink pen.

The shaft of a writing brush 2 is prismatic with the cap for brush 4, and promptly the shaft of a writing brush 2 is equilateral lumbar triangle shape or equilateral triangle with the cap for brush 4 cross sections, and present embodiment is selected equilateral triangle, and described equilateral triangle can be that the angle rib is clearly demarcated, referring to Fig. 2; Can be the corner angle rounding off also, referring to Fig. 3; The shaft of a writing brush 2 can adopt snap-fit attachment as shown in Figure 1 with the cap for brush 4; The size that is the shaft of a writing brush 2 upper ends is identical with the middle part; The shaft of a writing brush 2 is provided with the convex ridge of interruption or ring-type, is provided with groove at the cap for brush 4 inwalls, and both cooperations can realize that the cap for brush 4 is fastened on the shaft of a writing brush 2; The shaft of a writing brush 2 can adopt snap-fit attachment as shown in Figure 4 with the cap for brush 4, and promptly the size of the shaft of a writing brush 2 upper ends is less than the middle part, and the cap for brush 4 adopts convex ridge and groove fit to fasten with the shaft of a writing brush 2.

Three sides of the shaft of a writing brush 2 are respectively arranged with length scale (chi) 3, angle index (chi) 7, radius scale (chi) 13.Also can be provided with length scale (chi) 3, angle index (chi) 7 or scale of length on the cap for brush 4, scale of length can be set to 2:1-5:1, promptly 2 lattice to 5 lattice evenly is set in 1 centimetre.Take off the cap for brush, can measure length, angle or length ratio easily.

Wherein, the scale on the length scale (chi) 3 is normal evenly scale, and scale can adopt centimetre or millimeter be unit; During use, measure as required and get final product.0 of length scale (chi) 3 can be arranged at the middle part of length rule, to two ends up and down the counting scale of connection is arranged respectively, that is, upwards end is 0,1 from the middle part; 2,3,4,5; (corresponding unit for centimetre) is one group, also is 0,1,2 to the lower end; 3,4,5 ... (corresponding unit for centimetre) is one group.Also can begin counting on the length scale (chi) 3 from an end (like the lower end) of the shaft of a writing brush 2, promptly from 0,1,2,3,4,5 ... (corresponding unit be centimetre).

The angle index that is provided with on the angle index (chi) 7 is non-homogeneous scale; To two ends up and down the angle index line is set for benchmark by the reference measurement line at middle part (also being that angle is 90 degree lines) respectively, this angle index line adopts the setting of light refraction principle, and it is a graduation mark that the one of which group can adopt with per 1 degree, 5 degree or 10 degree; Another group then can only mark the graduation mark at special angle; Like 30 degree, 45 degree, 60 degree etc.; Also can all be set to same detailed graduation mark with two groups.If 0 portion placed in the middle of the scale on the length rule, then, the reference measurement line can be selected 0 scale of corresponding length rule 7; When measuring certain angle; 0 of the length scale (chi) 3 of the utility model is placed the angle end at this angle; A wherein line at one this angle of side superimposed of length scale (chi) 3, the angle index line on the angle index (chi) 7 that overlapped of another line (extended line) then is the angle at this angle; If length scale 3 was made angle index (chi) at 7 o'clock from an end of the shaft of a writing brush 2 counting, can with the length scale 5 (centimetre) or 6 (centimetre) locate as the reference measurement line, the making of angle index (chi) 7 is the same, during measurement, the same reason.Also can the length graduation mark be set, unified angle index line be set in other two sides a side, at this moment, though the angle index line is arranged at two sides, point-blank.

As shown in Figure 7, the radius scale on the radius scale (chi) 13 is non-homogeneous scale, its demonstration be the distance (being radius) between compasses two tiptoes.When two triangular pens combine; Through being arranged at the axis hole on the cap for brush 4; Penetrating screw axis 5 fixes two relative looselys of triangular pen; The upper end of pen card 6 is connected on the screw axis 5 through screw, and promptly the nut of pen card 6 upper ends matches with external screw on the screw axis 5, is arranged at pen on the screw axis 5 and blocks 6 and play the effect of screwing or loosening; Open two triangular pens, can carry out the compasses operation.Radius scale (chi) 13 on two triangular is relative.

As select the length of radius; Can carry out following operation: when two radius rules were staggered, the numerical value on the radius scale (chi) 13 that the position of inboard cross-point is aimed at was promptly represented the length (needs mark in the inboard of ruler through measuring in advance) of compasses radius; Thereby can draw circle according to the length of radius easily.

As shown in Figure 8, pen card 6 upper ends are screw axis 15, and screw axis 15 places in the axis hole of the cap for brush 4, and the axis hole two ends are bigger, and an end is provided with spring 14, and the other end is provided with the cap nut 16 that matches with screw axis 15, and screw axis 15 can screw in cap nut 16 or screw out.The cap for brush 4 is provided with erasing rubber 17.

When doing the compasses use, a pen is blocked 6 screw axis 15 twist in the screw line cap 16 of another cap for brush, can connect two pens, thereby can serve as compasses, carry out the picture circle.At this moment, a spring is in compressive state, and a spring is in extended state, but does not hinder the screw-in or the back-out of screw axis 15.

The above; Be merely the specific embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technical staff who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.
