Drawing device special for advanced mathematics

The invention belongs to the technical field of drawing devices, and particularly discloses a drawing device special for advanced mathematics. A device main body, a right-angle plate, a curve plate and a first column body are included, the right-angle plate is fixedly connected to the front surface of the device main body, the peripheral outer wall of the right-angle plate is connected with the peripheral outer wall of the device main body, and a diameter graduated scale is fixedly connected to the bottom end of the right-angle plate. The peripheral outer wall of the diameter graduated scale is connected with the peripheral outer wall of the front surface of the right-angle plate, the bottom end of the diameter graduated scale is fixedly connected with a diameter groove, and the first column body and a second column body on the diameter groove move towards the two ends of the diameter groove correspondingly till the distance between the first column body and the second column body is equal to the radius, then
