[0024] The rotating block 20 rotates inside the rotating groove 21, and the baffle 3 is fixedly connected to the outside of the connecting shaft 10;

[0025] Specifically, Figure 1 , Figure 3 and Figure 4 As shown, the three suction bottles are connected to the left side of the first outlet 2 and the bottom and top of the second outlet 9 through connecting pipes, so that the three suction bottles can be connected together. When the liquid flows to the suction bottle on the left side of the first outlet 2, the turning handle 5 is turned. The turning handle 5 drives the baffle 3 to rotate through the connecting shaft 10, so that the baffle 3 is parallel to the inside of the first outlet 2, and the liquid flows to the inside of the bottle on the side of the first outlet 2 through the right side of the first outlet 2. Before use, the turning handle 5 on the side of the second outlet 9 is turned. The turning handle 5 drives the baffle 3 inside the second outlet 9 to rotate through the connecting shaft 10, so that the baffle 3 inside the second outlet 9 contacts the inner wall of the second outlet 9 to prevent the liquid from flowing to the inside of other bottles through the second outlet 9.

[0026] Embodiment 2: The left side of the second three-way pipe 12 is embedded in the right side of the first outlet 2, and the left side of the outside of the second three-way pipe 12 is equipped with a sleeve 7. The two ends of the outside of the connection between the second three-way pipe 12 and the first outlet 2 are provided with fixing hoops 13, and the bottom and top ends of the fixing hoop 13 are respectively fixedly connected with the connecting block 6, and the inside of the connecting block 6 is provided with a mounting groove 15, and the inside of the mounting groove 15 is provided with a mounting bolt 8, and the rear end of the outside of the mounting bolt 8 is provided with a nut 14, and the inner side wall of the fixing hoop 13 is provided with a sealing gasket, and the sealing gasket and the fixing hoop 13 are wrapped around the outside of the connection, and the connecting block 6 is fixed by the nut 14 and the mounting groove 15;

After insertion, the two ends of the fixing hoop 13 are placed outside the connection, and then the mounting bolts 8 are screwed into the inside of the mounting groove 15 to fix the connecting block 6. The sealing gasket on the inner wall of the fixing hoop 13 can prevent the liquid from leaking out of the connection, thereby increasing the sealing of the connection, so that the first three-way pipe 1 and the second three-way pipe 12 can be spliced ​​together to facilitate the connection of three groups of suction bottles. The three suction bottles are connected to the left side of the first outlet 2 and the bottom and top of the second outlet 9 through the connecting pipe. When the liquid flows to the suction bottle on the left side of the first outlet 2, the turning handle 5 is turned, and the turning handle 5 drives the connecting shaft 10 The baffle 3 rotates to make the baffle 3 parallel to the inside of the first outlet 2, and the liquid flows into the bottle on the side of the first outlet 2 through the right side of the first outlet 2. Before use, rotate the turning handle 5 on the side of the second outlet 9, and the turning handle 5 drives the baffle 3 inside the second outlet 9 to rotate through the connecting shaft 10, so that the baffle 3 inside the second outlet 9 contacts the inner wall of the second outlet 9 to prevent the liquid from flowing into other bottles through the second outlet 9. Before rotating the turning handle 5, pull the pull plate 18, and the pull plate 18 drives the limiting rod 19 to disengage from the inside of the fixing hole 11, so that the turning handle 5 loses its fixation. After the turning handle 5 is rotated to a suitable position, release the pull plate 18, and the spring 17 drives the limiting rod 19 to be embedded in the fixing hole 11 again through elasticity, so that the turning handle 5 can be fixed to prevent the turning handle 5 from accidentally driving the baffle 3 to rotate and affecting use.
