A rotating shaft 208 is rotatably connected in the infusion head 1, one end of the rotating shaft 208 extends to the outside of the infusion head 1 and is fixedly installed with a turntable 207, and a driving gear 205 is fixedly installed on the outer side of the rotating shaft 208, and the driving gear 205 is located between the two sleeve plates 209, and the sides of the two sleeve plates 209 that are close to each other are fixedly installed with toothed plates 202, and the two toothed plates 202 are meshed and connected with the driving gear 205;

[0026] When in use, first the upper interface 4 and the connecting seat 5 are connected to the plastic infusion container, and then the two infusion tubes are connected to the two lower interfaces 6 respectively. At this time, the two infusion tubes can be infused at the same time. When only one of the infusion tubes is needed for infusion, the turntable 207 is then rotated to drive the rotating shaft 208 to rotate, and drive the driving gear 205 to rotate. Since the two tooth plates 202 are meshed and connected with the driving gear 205, and drive the two sleeve plates 209 to slide along the two columns 206 respectively, the two elastic balls 204 move at this time, and the moving directions of the two elastic balls 204 are opposite, until one of the elastic balls 204 moves to the opening corresponding to it and blocks this opening, and finally infusion is carried out through the other opening.
