Abstract: An improved sprinkler structure provides a fastener of a positioning ring for elastically fastening a water guiding pipe. A fastening dot of the positioning ring can engage with a tooth of a water inlet connector effectively so that the water guiding pipe does not detach easily. Water outlet direction of a first water passage and a second water passage is tangent with an impeller; therefore, when water is let out, the water pressure will push the impeller evenly to make the sprinkler to rotate evenly and smoothly. A push rod of a water inlet switching device is pivotally connected with a connecting rod. When the connecting rod is pushed, because a clearance is present between the connecting rod and a connecting groove, the force received by the connecting rod is partially converted into momentum of displacement when the push rod wiggles.
