Use the interval wheel to determine the interval
1. The base point that becomes the starting point should match the position of the blade of the pitch wheel
2. Hold the pitch wheel vertically and use it by pushing
3. If you push the fixed distance wheel forward, the end of the wheel axle will rotate, so you can set the interval of equal width
