Design scheme: a section of rope is tied to the top of the balcony on the second floor, and then through a movable pulley, which is connected with a heavy object under the wheel, and then bypasses a fixed pulley fixed above the balcony on the second floor, and then through a movable pulley, the same movable pulley is connected with the heavy object, and makes it share the gravity evenly with the previous fixed pulley. After the rope is wound out of the movable pulley, it is finally held in the hand and pulled directly on.
