embodiment
A kind of multifunction teaching drawing instrument, comprise ruler 6, angle scale 1, tightening dish 2, chalk holder 7, rod support 4, chi end seat 12, level meter 11 part, described ruler 6 front is provided with dimension line 9, angle graticule 5 and horizontal graticule 10, the groove slided for chalk holder 7 is offered in the middle of ruler, described angle scale 1 is positioned at ruler left end, angle scale 1 front is provided with 360 ° of bisects angle lines 3, described angle scale 1, ruler left part arranges the through hole coaxial with rod support axle 18, and fixed by tightening dish 2, described chalk holder 7 is provided with chute 16, perspective board 17, retaining sleeve 15, nut 13, described chute 16 is slidably matched with ruler medial launder, perspective board 17 is positioned at above chute 16, perspective board 17 is provided with yardstick graticule 8, retaining sleeve 15 one end is provided with screw thread and offers cross recess, chalk inserts in cross recess, the nut 13 be equipped with retaining sleeve is by chute 16, perspective board 17, chalk is fixed on ruler, described chi end seat 12 is positioned at ruler 6 right-hand member, top arranges a level meter 11, bottom described rod support 4 and chi end seat 12, magnet sucking disc is set, i.e. 14 chi end seat magnet sucking discs, 19 rod support axle magnet sucking discs.
When drafting with when measuring horizontal line, be horizontal by the level meter 11 on ° angle line of 0 on angle scale 1 and ruler, mobile chalk holder 7, on perspective board, yardstick graticule 8 aligns with the dimension line 6 on ruler, can draw or measure horizontal line.
When drafting or when measuring angle, fixing rod support 4,0 of angle scale 1 ° of angle line is horizontal and keeps motionless, ruler 6 is rotated around rod support axle 18, according to given angle value along angle line, angle graticule 5 on the ruler angle line 3 corresponding with on angle scale is aligned, and mobile chalk holder 7, can draw or measure arbitrarily angled.
When drafting or when measuring line segment, angle graticule 5 on ruler is consistent with the rectilinear direction that will draw with horizontal graticule 10 or overlap with the straight line that will measure, mobile chalk holder 7, on perspective board, yardstick graticule 8 aligns with the dimension line 9 on ruler, can draw or measure straight line.
When drawing or measuring bowlder, fixing rod support 4, make the center of rod support axle 18 concentric with the center of circle, chalk holder 7 is moved by given radius value, yardstick graticule 8 on perspective board is overlapped with dimension line on ruler 9, nut 13 being screwed retaining sleeve 15 makes chalk holder 7 be fixed on ruler 6, rotates ruler 6 draw out required circle or circular arc with fixing rod support axle 18 for the center of circle.
During use or the not used time, be adsorbed on blackboard by this teaching aid, magnetic blackboard preferably selected by blackboard.
