[Prior art]

 As shown in FIG. 4, one of the most common and commonly used drafting machines is that one bottom pedestal 8 is provided under the drafting machine. The bottom pedestals 8 are opposite to each other and are perpendicular to the bottom pedestal 8. A columnar body 81 is provided, and one support bar 82 is provided at each top end of the columnar body 81 on both sides thereof, and an adjusting volume 83 is provided on one side of the columnar body 81 of both the support bars 82. One end of each of the adjusting volumes 83 also penetrates the column body 81 and extends along the support bar 82, and the top ends of both support bars 82 are also pivotally connected to both sides of the frame body 84. One drawing board 85 is fixed on the frame body 84, and one support bar 86 is provided at an appropriate position on each side of the frame body 84. One end of each support bar 86 is on the column body 81. The pivot hole 88 of the adjusting volume 87 of FIG.

In such a device structure, when the angle of the drafting machine is adjusted, not only the support bar 86 below the drafting board 85 is a bar body that is curved but also the drafting board 85 is kept at a constant angle. It was not possible to go up and down and make major adjustments. Further, the support bar 82 for adjusting the elevation of the drafting plate 85 is fixed on the pillar body 8 1 along the adjustment volume 83, so if the volume 83 is excessively turned outward, it will be easy to draw a draft. The entire plate 85 was dropped onto the column 81 for a long time, and as a result, there was a situation where it was bumped or the user's hand was pressed and scratched, which was not ideal for use.
