The holding tank I2 is used for placing a round-bottom flask with small volume capacity (the outer diameter of the bottle body is smaller), the holding tank II 3 is used for placing a round-bottom flask with large volume capacity (the outer diameter of the bottle body is larger), and when the round-bottom flask is used, the proper holding tank I2 or holding tank II 3 is placed upwards according to the specification of the round-bottom flask which is placed according to actual needs.

The positioning mechanism comprises a vertical telescopic rod 4, a connecting rod 5 and a positioning ring 6, wherein one end of the connecting rod 5 is rotationally connected with the upper end of the vertical telescopic rod 4 through a rotating shaft 7, and the other end of the connecting rod 5 is fixedly connected with the back surface of the positioning ring 6. The lower extreme of perpendicular telescopic link 4 inlays locates in main part 1, and circular holding tank 8 has been seted up to the top of main part 1 and the corresponding position of the upper end of perpendicular telescopic link 4, and bar holding tank 9 has been seted up to the top of main part 1 and the corresponding position of connecting rod 5, and the one end and the circular holding tank 8 of bar holding tank 9 are linked together, and the other end is linked together with the holding tank 2 or holding tank two 3 that the position corresponds. When in use, the upper end of the vertical telescopic rod 4 is pinched and lifted upwards, so that the connecting rod 5 is separated from the strip-shaped accommodating groove 9, the positioning ring 6 is separated from the accommodating groove I2 or the accommodating groove II 3, and the positioning ring 6 is rotated to be positioned on one side above the accommodating groove I2 or the accommodating groove II 3. The round-bottomed flask is placed in the first accommodating groove 2 or the second accommodating groove 3, the inner walls of the first accommodating groove 2 and the second accommodating groove 3 are of coarse structures, friction force between the round-bottomed flask and the inner wall of the first accommodating groove 2 or the inner wall of the second accommodating groove 3 can be increased, the position of the round-bottomed flask is effectively fixed, and the probability that the round-bottomed flask is toppled over is reduced.
