Abstract: A water sprinkler comprises a housing, a linking mechanism, a transmission rod, and a spray head. The housing is provided therein with a receiving compartment for housing the linking mechanism which is composed of a pump blade, a link wheel and an actuation wheel. The transmission rod is fastened at one end thereof with the actuation wheel and at another end thereof with the spray head having a plurality of jet nozzles for emitting a stream of water. The transmission rod is driven by the actuation wheel which is actuated by the pump blade. As the pump blade is driven by the incoming water current via an inlet of the housing, the spray head is actuated by the transmission rod to make a 360-degree roation so as to spray water in all directions.
