[0026] Working Principle: In use, the placement plate 8 is first moved out of the culture chamber 2 from the moving groove 10. Then, the positions of the fixing plate 16 and clamping plate 18 are adjusted according to the size of the culture dish. The positions of the fixing plate 16 and clamping plate 18 are adjusted by rotating the first nut 17 and the second nut 20. After adjustment, the fixing plate 16 and clamping plate 18 are inserted into the corresponding adjustment groove 14 from below. Then, the first threaded post 15 is rotated and screwed into the threaded groove 26 for fixation. A corresponding number of culture dishes are then placed between the fixing plate 16 and clamping plate 18. The fixing plate 16 and clamping plate 18 are further adjusted by using the first nut and the second nut to further clamp both ends of the culture dish. Finally, the limiting plate 241 is inserted into the placement plate. Inside the groove 13, the moving plate 243 is inserted into the slot 242 through the sliding groove 21, and then the second threaded post 23 is inserted through the moving circular groove 244. The third nut is then moved to the side of the moving plate 243 through the second threaded post 23. Then, by rotating the third nut, the limiting plate 241 is moved to the side of the culture dish in conjunction with the moving plate 243 to limit the two sides of the culture dish. The culture dish can be placed again according to the above steps. The two ends of the culture dish are clamped by the fixing plate and the clamping plate. Then, the two sides of the culture dish are limited by the limiting plate 241 in conjunction with the limiting plate 241 of the previous set. In this way, culture dishes of different sizes can be clamped so that the culture dishes will not move and spill during the movement.
