The blade ring receives the hub and has a first mounting end and a second mounting end opposite to the first mounting end. When the position end abuts the second mounting end of the blade ring, the blades extend aslant from the blade ring toward a counterclockwise direction relative to the circular wall. When the position end abuts the first mounting end of the blade ring, the blades extend aslant from the blade ring toward a clockwise direction relative to the circular wall.
