[0061] The driving mechanism 5 comprises a first motor 51, and a transmission shaft 52 is fixed to the power output end of the first motor 51;

[0062] The top end of the transmission shaft 52 passes through the bottom wall of the mounting platform 3 through a bearing and extends into the cavity. A driving gear 53 is fixed to the top end of the transmission shaft 52.

[0063] The driving gear 53 is symmetrically meshed with a plurality of external gear rings 54;

[0064] The outer toothed ring 54 is fixed to the outside of the corresponding test tube holder 4 .

[0065] The test tube holder 4 comprises a mounting seat 41, a test tube slot 42 is provided on the top wall of the mounting seat 41, and a rotating ring 43 is rotatably mounted on the outer wall of the mounting seat 41;

[0066] A hemispherical block 44 is symmetrically fixed to the inner wall of the rotating ring 43;

[0068] One end of the clamping column 45 extends into the test tube slot 42 , and a limiting block 46 is symmetrically fixed to the side wall of the clamping column 45 .

[0069] A limiting sliding groove is provided inside the mounting seat 41 at a position corresponding to the limiting block 46 , and the limiting block 46 is slidably installed in the limiting sliding groove.

[0070] A circular groove 11 is formed on the side wall of the mounting seat 41 . The rotating ring 43 is rotatably mounted in the circular groove 11 . The outer gear ring 54 is fixed on the outer wall of the rotating ring 43 .

[0073] A pull plate 66 is fixed to the top of the pin 63, and a limit plate 64 is fixed to the shaft of the pin 63 located in the housing 62;

[0074] The limit plate 64 is slidably mounted in the housing 62, and a spring 65 is fixed between the top wall of the limit plate 64 and the top wall of the inner cavity of the housing 62;

The limiting mechanism 6 is configured to limit the mounting platform 3.

At the same time, the positioning groove 9 and the limit mechanism 6 can play a positioning role to ensure that the mixing and stirring mechanism 8 corresponds to the position of the test tube.

[0078] The mixing and stirring mechanism 8 comprises a mounting shell 81, which is fixed to the movable end at the bottom of the cylinder 7, and a second motor 82 is fixed at the center of the top wall of the mounting shell 81;

[0079] The power shaft at the bottom of the second motor 82 passes through the top wall of the mounting shell 81 through a bearing and is fixed with a driving gear 83;

[0080] The driving gear 83 is installed inside the mounting shell 81, and a plurality of driven gears 84 are symmetrically meshed on the outer side of the driving gear 83;

[0081] A spiral stirring rod 85 is fixed at the axial center position of the bottom wall of the driven gear 84;

[0082] The spiral stirring rod 85 passes through the bottom wall of the mounting shell 81 through a bearing and extends to the outside of the mounting shell 81 .

[0083] In this embodiment, the mixing and stirring mechanism 8 is used to evenly mix the microbial strains in the test tube with the culture solution to ensure the normal cultivation of the microbial strains.
