description The utility model discloses an N-leaf rose line instrument, and the N-leaf rose line instrument comprises a drawing arm, a paintbrush adjusting rod, a paintbrush part and a gear drive mechanism, the paintbrush part is mounted on the paintbrush adjusting rod for moving along the paintbrush adjusting rod, the paintbrush adjusting rod is mounted on the drawing arm via the gear drive mechanism; when the drawing arm is driven for rotating around the shaft, namely the first rotary shaft, the paintbrush adjusting rod rotates along the rotary of the drawing arm and is driven by the gear drive mechanism driving the drawing arm for reversely rotating along the other shaft, namely the second rotary shaft, which is parallel to the first rotary shaft. The N-leaf rose line instrument is simple in structure, convenient to carry, convenient in drawing operation without connection to other devices, directly operated by hands and suitable for the teaching field, the N-leaf rose line instrument can draw the straight line, round, oval, N-leaf rose line and other multiple figures in favour of further studying on the important curve as rose line in advanced mathematics for the researchers and learners.
