The utility model discloses a novel water-saving irrigation device. The device comprises a cone bottom, a shell and a top cover, a first handle is arranged on the shell; a horizontal optical axis is fixed on the inner side of the shell; a first sliding block and a second sliding block are arranged on the horizontal polished shaft in a sliding manner; a first puncture rod and a second puncture rodare respectively fixed on the first sliding block and the second sliding block; the first sliding block and the second sliding block are rotationally connected with a first connecting rod and a secondconnecting rod correspondingly. The upper ends of the first connecting rod and the second connecting rod are hinged to the same fixing block, the middle of the top cover is in threaded connection with a second handle, the lower portion of the second handle is connected with the upper portion of the fixing block through a sleeve, water supply channels are formed in the first puncture rod and the second puncture rod, and a water supply hose penetrates through the top cover. Compared with the prior art, after the first puncture rod and the second puncture rod are punctured into soil, symmetricalwater supply to the two sides of the equipment can be achieved; the actions of the first puncture rod and the second puncture rod can be controlled by rotating the second handle, so that the operation is simple, convenient and labor-saving.
