Face is provided with the second chi plate, and the second chi plate upper surface on the left of the rotating shaft is provided with micro-step motor, the micro-step motor
Output end be provided with and be provided with controller with the second gear first gear set that engages of set, the upper surface middle part of the second chi plate,
The controller is electrically connected with micro-step motor.
Preferably, 90 degree of graduation marks of the left side edge of the first chi plate and Angle protractor overlap.
Preferably, the axle center of the rotating shaft overlaps with the center of circle of Angle protractor.
Preferably, the upper end right side edge of the second chi plate is provided with pointer.
Compared with prior art, the beneficial effects of the utility model are：The inching gear of the new teaching instrument of surveying and mapping
Spliced by the first chi plate and Angle protractor, drive the second chi plate that Angulation changes occur relative to rotating shaft by micro-step motor,
That is there is angle change in the second chi plate, pointer shows the size of angle changing, can be accurate relative to Angle protractor and the first chi plate
Geometrical line at any angle is drawn, makes sucker suction on demonstration board, it is not necessary to help flat, improve the drawing efficrence of lecturer, should
The inching gear simple structure of new teaching instrument of surveying and mapping, drafting accuracy is high, easy to use.
