By adopting the technical scheme, the slide rod can be reliably connected with the shifting block and the clamping teeth.

Furthermore, the limiting clamping blocks are connected with the sliding grooves in a sliding mode, and the number of the limiting clamping blocks is two.

Through adopting above-mentioned technical scheme, can be according to the angle of movable ruler realizes spacing fixture block for the convenient slip of movable ruler is convenient for realize the movable ruler is spacing.

Furthermore, the tooth pitch of the limiting rack is 1mm, and the clamping tooth block is meshed with the limiting rack.

By adopting the technical scheme, the drawing precision can be ensured.

(III) advantageous effects

Compared with the prior art, the utility model, following beneficial effect has:

for solving current train operation chart not only need the manual work to adopt single drawing rule to measure repeatedly and compare when artifical manual drawing for the step of drawing is comparatively loaded down with trivial details, has reduced the accurate nature of drawing, and the lines is drawn more slowly in drawing process, very big reduction the drawing efficiency's of figure problem, the utility model discloses a main scale, upper ruler, lower ruler, movable ruler, spacing rack and spacing fixture block's design not only can provide diversified measurement reference for the graphics plotter in drawing process, effectively avoid artifical repeated measurement in drawing process to compare, simplified the drawing step, ensured the accurate nature of drawing, can realize the quick drawing of lines in drawing process moreover, improved the drawing efficiency of figure, the practicality is good.
