Abstract: A quickly installed spray nozzle is composed of a nozzle holder which is provided at the top with a water outlet that extends with an appropriate distance connect tube which is provided with a protuberance piece at both sides of the outer wall, and a nozzle head extends to an appropriate length with a casing at one end thereof. The inner wall of said casing is matched with the diameter of the connect tube. The casing is provided with a guide trough and a wedge trough, and further provided with a washer at the end thereof. The nozzle head uses the casing to insert directly to the connect tube of the nozzle holder, so as to let the protuberance piece of the connect tube to come into the guide trough of inner wall casing. The nozzle head removes to an appropriate angle so as to let the protuberance piece insert into the wedge trough and reach the nozzle head to install quickly in place.

Abstract: A water nozzle control valve seat is constructed of a body, a plug tube, a valve tube member, a slide rod, a press rod member, a tension spring, a clip plate, and an elasticity element. The valve seat tube is constructed at the upper section of tubular handle which has provided with an entrance water tube at upper end thereof connecting to the rear bottom of said valve seat tube. An exit water tube is provided between the middle top section of valve seat tube and barrel. An external tube is provided with an opening at bottom front side connecting the exit water tube and barrel. A receiving room of wedge is formed on the water nozzle body located at top and rear side of the external tube. The clip plate is fastened pivotally beneath the barrel locating at front of valve seat tube, and corresponds to the press rod member providing with a wedge hole and further providing with a convex at the bottom section thereof that is relatively to the tubular handle.

Abstract: A garden hose nozzle is composed of a cylindrical housing, a toothed disk, a shaft member and a fastening bolt. The fastening bolt is used to fasten the tooth disk and the shaft member in the stepped axial hole of the cylindrical housing. The shaft member can be rotated manually such that the interstices of various sizes are formed between a tapered ring edge of the stepped axial hole of the cylindrical housing and the tapered portion of the shaft member for regulating the sprinkling pattern of water.
