Although this is convenient to construct and has a low cost, it creates irrigation dead zones and cannot achieve full sprinkler coverage. Summary of the Invention

Multiple atomizing nozzles are spaced apart on the lower side of the nozzle frame, and the nozzle frame is connected to the top of the telescopic tube through a flexible hose. The nozzle frame is hinged to a piston rod at one end near the telescopic tube, and the other end of the piston rod is hinged to the outer wall of the branch tube. The T-joint is equipped with a tripod bracket, and a screw rod is fixedly installed at the center of the tripod bracket inside the branch pipe; a nut that meshes with the screw rod is provided at the center of the bottom end face of the telescopic pipe; the outer wall of the nut is connected to the inner wall of the telescopic pipe by a side rod. A motor is installed on one side of the main pipe, and a drive gear is connected to the output shaft of the motor.

[0007] Preferably, the spray head frame is symmetrically provided with two.

[0008] Further, the limiting installation clamp comprises a connecting ring fixedly connected to the outer wall of the top of the telescopic pipe, and two installation ears are symmetrically provided on the two sides of the connecting ring and respectively connected to the spray head frame near the tail end.

[0009] Further, the installation ear, the spray head frame and the piston rod are located in the same vertical plane.
