This is a very simple model fully hand operated. I provide a spring at the top in order to make the model return to the closed position with an easiness. I give more importance to make the model easy to manufacture as well as easy to use. I provide four steps, so that the user can use any mode as they need. there is a turn able handle at the bottom. The user can push the lever along with the bottom plate and turn clockwise to select each steps.
