The use process of the new surveying ruler provided by the utility model is as follows: when the surveying ruler needs to be used to draw a circle, the user rotates the first rotating button 5. Since the first rotating button 5 is fixed to the rotating worm 6, the rotation of the first rotating button 5 drives the rotating worm 6 to rotate, so that the rotating worm wheel 7 meshing with the rotating worm 6 also rotates, and since the rotating worm wheel 7 is fixedly connected to the rotating roller 8, the rotation of the rotating worm wheel 7 drives the rotating roller 8 to rotate, so that the rotating gear 9 fixed to the rotating roller 8 also rotates, and since the rotating gear 9 is meshingly connected to the moving rack 10, the rotation of the rotating gear 9 rotates the moving rack 10, so that the moving rack 10 meshing with the rotating gear 9 moves, and since the moving rack 10 is fixed to the first moving plate 11, the movement of the moving rack 10 drives the first moving plate 11 to move, so that the fixed cone 12 fixed to the first moving plate 11 also moves, and at this time the fixed cone 12 contacts the drawing paper;

At this time, the user rotates the second rotating knob 14. Since the second rotating knob 14 is fixed to the threaded rod 13, the rotation of the second rotating knob 14 drives the threaded rod 13 to rotate. Since the threaded rod 13 is threadedly connected to the second movable plate 15, the rotation of the threaded rod 13 drives the second movable plate 15 to move. With the fixed cone 12 as the center of the circle, the radius of the drawn circle can be adjusted by comparing the indicating arrow 16 with the scale.

When it is necessary to draw a longer line, the user presses the fixed plate 20 downwards. Since the fixed plate 20 is fixedly connected to the third movable plate 18, the movement of the fixed plate 20 drives the third movable plate 18 to move. At this time, the third movable plate 18 is no longer in contact with the card slot 19, and the third movable plate 18 no longer restricts the auxiliary measuring ruler 3. The auxiliary measuring ruler 3 can rotate around the first connecting rod 2. At this time, the drawing ruler can be unfolded to draw long lines.
