Description of drawings
Fig. 1 is profile and the structural representation of an embodiment of the utility model.
The specific embodiment
By following embodiment the utility model is further elaborated.
Referring to shown in Figure 1, the isograph main body 1 of present embodiment is by 10 whole compositions of parallel device at its anterior chi body 2 and rear portion.Chi body 2 last rows are provided with metric system length scale 3-1, have a row in centimeter scale line rear end and draw circular hole 4-1 at a distance of 1 centimetre metric system, chi body 2 the first two row are provided with length scale 3-2 made in Great Britain, have a row 1/2 inch graduation mark rear end and draw circular hole 4-2 at a distance of 1/2 inch English system.Chi body 2 postmedians are provided with protractor 5, are respectively equipped with semicircle dead slot 5-2, angle index 5-1 and circle center hole 5-3 above.Parallel device 10 is made up of roller shaft 9 and supporting cover 6, and these roller shaft 9 and arranged on left and right sides portions are provided with the roller 7 that fine and closely woven straight trough is rolled on a surface, is provided with public affairs, two circle length scales 8 made in Great Britain at roller shaft 9 middle parts.Described roller shaft 9 by its and arranged on left and right sides end axle 11 expansion bearings on the hood-shaped supporting cover 6 of semicircle, its semicircle cover upward, and the corresponding length scale in top 8 places are provided with horizon glass 6-1 thereon, draw on this minute surface an index line that is parallel to roller shaft 9 axis is arranged, by this minute surface 6-1 and on index line, just can read the distance of chi body 2 translations easily.Operation also has opening in supporting cover 6 top and arranged on left and right sides for convenience.
