1. A long-handled spray gun with a rotary head, comprising a connector head, a rotary member, a fixed member, a connection part, a long tubular rod, a block, a fixing bolt, a small and a large ring washers and a flexible locating means wherein said connector head having internal threads disposed at one end is screw joined to said rotary member, and said connection part is securely engaged with said fixed member and said long tubular rod respectively at both ends thereof;

  • said long-handle spray gun with a rotary head of the present invention being characterized by that,said rotary member having an externally threaded tubular front end, a water outlet port disposed at the center of the rear end thereof, a staged groove disposed transversely at one side of said rear end thereof in communication with said externally threaded tubular front end thereof via said water outlet port thereof, and a tubular column disposed at the inner side of said staged groove thereof;

    a multiple of locating slots being distributed in a semi-circle at the upper side of said staged groove thereof, and a staged through hole being disposed at the center of said tubular column thereof;

    said fixed member being equipped with a fixing post disposed transversely at one side of the front end thereof for said small ring washer to be adapted thereto, and a circular outer flange circumscribing said fixing post thereof for said large ring washer to be adapted thereto;

    said fixing post having a serrated polygonal head projecting at the front end thereof and internal threads disposed at the interior thereof;

    said fixed member also including a fixing cavity disposed at one upper side of said circular outer flange thereof for said flexible locating means to be adapted thereto at one end, a fixing joint disposed at the rear end thereof, and a water inlet hole disposed at the center of said fixing joint thereof in communication with the space defined by said circular outer flange and said fixing post thereof;

    said connection part, bent in an angle, having an upper and a lower coupling holes disposed at both ends thereof;

    said long tubular rod being a tube body of proper length with a control handle disposed at the lower section thereof;

    said block having serrated polygonal flange disposed at one inner side thereof, and a slot disposed at the center thereof;

    in assembly, said staged groove and said tubular column thereof are led and engaged with said circular outer flange and said fixing post thereof with said large and small ring washers adapted thereto respectively;

    said flexible locating means is inserted to one of said locating slots thereof for proper location thereof;

    said serrated polygonal head thereof is led and abutted against said staged through hole thereof;

    said block is joined to said serrated polygonal head via said serrated polygonal flange thereof securely engaging therewith, and said fixing bolt is screwed up to said internal threads of said fixing post thereof so as to pivotally secure said rotary member and said fixed member thereof;

    whereby, via said rotary member, said connector head can be adjusted stepwise into a proper angle for use;

    when said connector head is pushed up or down, said rotary member screw joined to said connector head thereof will pivotally rotate therewith and then relocated into position via said flexible locating means properly engaged with one of said locating slots thereof so as to easily and quickly adjust said connector head thereof into a proper angle for use.
