[0024] The limit baffle 4 forms a rotating structure through the rotation damper 5 and the fixed seat 6, and the movable range of the limit baffle 4 is 0°~90°. Open the top limit baffle 4, rotate the culture dish 9 to dislocate the buckle, and then the culture dish 9 can be removed and replaced, which is convenient for replacing the culture dish 9 and also convenient for limiting the position of the culture dish 9.

[0025] The rotary joint includes a fixed part 7, the outer side of which is connected to a movable part 8, and the center line of the fixed part 7 coincides with the center line of the movable part 8, which facilitates the fixation of the culture dish 9 and ensures that the culture dish 9 can be rotated and controlled.

[0026] The connecting component 10 includes a movable seat 1001, a guide ramp 1002 and a bayonet 1003. The outer side of the movable seat 1001 is integrated with the guide ramp 1002, and the middle part of the guide ramp 1002 is provided with a bayonet 1003. The bottom of the culture dish 9 has a convex point that cooperates with the bayonet 1003. The culture dish 9 can rotate along the guide ramp 1002 and finally be stuck on the movable bayonet 1003, so that the culture dish 9 is firmly fixed on the centrifugal culture rotating device.

[0027] The locking assembly includes an electromagnet shell 13, a metal fixed shell 14, a magnetic metal disk 15 and an electromagnet body 16. The metal fixed shell 14 is installed inside the electromagnet shell 13, the magnetic metal disk 15 is installed on the inner side of the metal fixed shell 14, and the electromagnet body 16 is installed on the outer side of the magnetic metal disk 15.
