The present invention is provided with an assembly for producing forficiform spray, which comprising a base body, the base body is disposed with a waterway inside; the waterway includes an inlet, an outlet and a circular cavity, the circular cavity is connected between the inlet and the outlet; the diameter of the outlet is larger than that of the inlet, the outlet is conical shaped with big end down; the joint of the inlet and the circular cavity is chamfered arc. When water flows into the cavity from the inlet, with the characteristics of the water, the outlet water forms a forficiform water of periodicity open and close; the present invention is full in granule, better suction effect, visual effect and massage effect.
