The specific embodiment
See also accompanying drawing.Fig. 1 is the utility model how much mapping schematic diagrames, and wherein geometry coordinate machine is by geometry coordinate machine 1, bar ruler 2, radius hole 2-2, protractor 3, center of circle 3-1, metric scale 4, working edge 4-2, foot rule 5, foot rule working edge 5-2, chi 6, ruler 7, mapping groove 8, numeral 9, scale 10, material-saving hole 11 constitutes, and it is characterized in that the center of circle 3-1 of the protractor 3 of described geometry coordinate machine 1, with the metric scale initial point 4-1 of metric scale 4 at a point; The zero degree initial line of protractor 3 and the working edge 4-2 of metric scale 4 be at a line, geometry coordinate machine 1 range structure changeable.
Metric scale 4, foot rule 5 pass protractor 3 the zero degree initial line up and down to center of circle 3-1, protractor 3 has adaptive change with metric scale 4 and foot rule 5 on numeral, scale, foot rule initial point 5-1 and metric scale initial point 4-1 coexist on the longitudinal axis, and center of circle 3-1 has solid and hollow form setting.
The radius hole 2-2 that also comprises ruler 7 is distributed in metric scale 4, on foot rule 5 and chi 6 the scale, arranges out the radius ordinal number.The radius value of radius hole 2-2 is provided with by the scale metering unit amount of determining on each yardstick, metric scale 4 with 0.25,0.5,0.75 and 1 millimeter radius unit, the numerical value that numerical value is millimeter is extended in the back, arrange out the diameter precision of drawing and reach 0.5 millimeter, the result of 1 millimeter ordinal number diameter, when the numerical value of mapping radius value surpasses in numeral 9, obtain on the scale 10, the size of radius distance value is to be arranged on metric scale 4, foot rule 5,2-2 hole, the radius hole bit architecture of chi 6 digital high scales, indicate the number of division word reduction general designation on ruler and the protractor, the radius hole 2-2 of ruler 7 extends row's example in the positive negative direction of chi initial point.
The limit that the zero degree initial line of protractor 3 and the working edge 4-2 of metric scale 4 form, and between the two chi limits to the foot rule working edge 5-2 of adjacent foot rule 5, the saturating empty mapping groove 8 that becomes.Mapping groove 8 is intuitively seen the picture testee during measurement, also provides fit structure for inserting paintbrush.
Metric scale 4, foot rule 5 and chi 6 with protractor 3 binding sites, can exchange setting.
With the center of circle 3-1 of protractor 3, the chi that zero degree initial line overlaid combines, can be arranged to metric scale 4, wherein a kind of of foot rule 5 and chi 6, the range changeable of each chi.
Material-saving hole 11 is opened in the blank space on the geometry coordinate machine 1, and batch process can be saved more material.
Fig. 2 is a ruler schematic diagram of the present utility model, and radius hole 2-2 distributes and is combined on the scale 10 on the bar ruler 2.On the figure discal patch ruler 2 respectively with 0.25,0.5,0.75 and 1 millimeter radius unit, the numerical value that numerical value is millimeter is extended in the back, arranges out the diameter precision of drawing and reaches 0.5 millimeter, the result of 1 millimeter ordinal number diameter, when the numerical value of mapping radius value surpasses in numeral 9, obtain on the scale 10, one group of scale, it is 0.25,0.5 that two groups of numerical value row examples go out the different length measurement unit, 0.75 and 1 millimeter radius value sets up separately, with unit is 0.25,1.25,2.25 of millimeter, 3.25,4.25 radius value is drawn circle, just obtains diameter 0.5,2.5,4.5,6.5,9.5 circle, ordinal number do not have 1,1.5,2,3,3.5,4,5,6,7,8,9, but all said method row example makes up out with 0.5,0.75 and 1 millimeter unit, the radius of 10 millimeters units of diameter of radius hole 2-2 is located at numeral 9, on the scale 10, similarly be the setting of method structure of the radius ordinal number of above-mentioned geometry coordinate machine 1, foot rule 5 and chi 6 is with its length-specific system unit numeral 9, the routine radius value of scale 10 rows is arranged example, the length range structure changeable of bar ruler 2 on bar ruler 2.
