[0039] It is understandable that matters not described in detail in the present invention are all well-known technologies to those skilled in the art.

[0040] The working principle of the above embodiment is:

[0041] (1) When the clamping structure of the culture dish automatic assembly machine is needed, the lower covers and upper covers of the four culture dishes are transported to the bottom of the front and rear mounting plates 10 respectively through the external slide rails by the external feeder.
