[0027] Adjusting plate 13 is set to the curve shape of the slope gradually reducing from left to right, when adjusting plate 13 moves up at uniform speed, horizontal rod 15 moves left and the moving speed of horizontal rod 15 gradually increases, when adjusting plate 13 moves down at uniform speed, horizontal rod 15 moves right and the moving speed of horizontal rod 15 gradually decreases.

[0028] When using, rotating rod 2 rotates, water flows through water supply pipe 1, rotating rod 2, intermediate pipe 23 and sprays outward to water outlet spray pipe 22, and water outlet spray pipe 22 swings up and down, so that the trajectory of water outlet spray pipe 22 is spiral shape, when the swinging speed of water outlet spray pipe 22 is fixed and the water output of water outlet spray pipe 22 is fixed, the irrigation amount of the inner circle of spiral is necessarily greater than the irrigation amount of the outer circle of spiral.
