Two ratchet gears are rotatably received within the receptacle and rotated in different directions, a barrel and a shaft are rotatably received within the receptacle and rotated in different directions, and a valve controlling device may be used for controlling the water to flow through the shaft, such as to flow through the shaft intermittently.
