The specific implementation mode is as follows: when the culture dishes 23 are stacked on the base 3 and shake in the transportation process, the base 3 is communicated with the stacked culture dishes 23 to be poured together; the bottom surface of the transportation thermostat relieves the restriction on the first slide bar 21 in the base mechanism 1; the first slide bar 21 drives the first slide block 18 to slide downwards along the first sliding chute 10; the first limiting inclined surface 20 acts on the first limiting block 14, so that the first limiting block 14 slides outwards along the second sliding groove 12 and enters the corresponding limiting ring groove 33; the first limit spring 15 is compressed; at the same time, the first slide bar 21 in the base mechanism 1 releases the restriction on the second slide bar 49 in the lowermost dish mechanism 2; under the action of the restoring force of the second return spring 32, the second slide block 46 drives the second slide rod 49 to slide downwards along the third slide groove 38; the second limiting inclined surface 48 on the second sliding block 46 acts on the second limiting block 42, so that the second limiting block 42 slides outwards along the fourth sliding groove 40 and enters the corresponding limiting ring groove 33; the second limit spring 43 is compressed; the downward movement of the second slide bar 49 in the lowermost culture dish mechanism 2 frees the restriction of the second slide bar 49 in the upper culture dish mechanism 2; under the restoring force of the corresponding second return spring 32, the second slide block 46 in the upper petri dish mechanism 2 drives the corresponding second slide rod 49 to slide downwards along the third slide groove 38; the second limiting inclined surface 48 on the second sliding block 46 in the upper culture dish mechanism 2 acts on the corresponding second limiting block 42, so that the second limiting block 42 slides outwards along the fourth sliding groove 40 and enters the corresponding limiting ring groove 33; the corresponding second limit spring 43 is compressed; because the first limiting blocks 14 and the plurality of second limiting blocks 42 are clamped in the corresponding limiting ring grooves 33, the culture dish 23 superposed on the base mechanism 1 cannot slide off the base 3; thereby avoiding the damage of the culture dish 23 caused by collision scattered; meanwhile, a plurality of culture dishes 23 are stacked on the base 3 in an overlapping mode, the space is saved, more culture dishes 23 can be placed in the incubator, more culture dishes 23 can be transferred simultaneously, and the transfer efficiency of the culture dishes 23 is improved.

When the culture dish 23 stacked on the base 3 is inclined together due to shaking, the culture solution in the culture dish 23 cannot spill out due to the sealing effect of the sealing cover 26, so that the loss is avoided; at this time, the first slide bar 21 slides downwards to the extreme position under the action of the first return spring 22; the second slide rods 49 in the culture dish mechanisms 2 slide downwards to the limit positions under the action of the corresponding second return springs 32, and the first return springs 22 and the second return springs 32 in the culture dish mechanisms 2 restore and release energy; the first limiting blocks 14 and the second limiting blocks 42 in the culture dish mechanisms 2 completely limit the corresponding limiting sliding grooves; the base mechanism 1 and the culture dish mechanism 2 which are overlapped together are held up by two hands and are vertically placed on the bottom surface of the incubator; under the action of gravity of the culture dishes 23, the bottom surface of the incubator enables the first slide bar 21 to drive the first slide block 18 to slide upwards to an initial position; the first stopper slope 20 releases the restriction on the first stopper 14; the first stopper 14 slides out of the corresponding stopper ring groove 33; the first limit spring 15 is restored to the original state, and the first return spring 22 is stretched again; the first slide bar 21 pushes a second slide bar 49 in the lowest culture dish mechanism 2 to drive a second slide block 46 to slide upwards; the second return spring 32 is again stretched; the second limit inclined surface 48 on the second sliding block 46 relieves the limit of the second limit block 42; the second limiting blocks 42 slide out of the corresponding limiting ring grooves 33; the second limit spring 43 is restored; the second slide bar 49 in the lowest culture dish mechanism 2 pushes the second slide bar 49 positioned above the second slide bar 49 to move upwards; the second upper slide bar 49 drives the corresponding second slide block 46 to move upwards; the second return spring 32 in the upper dish mechanism 2 is stretched again; the second slider 46 in the upper culture dish mechanism 2 releases the restriction on the corresponding second stopper 42; the upper second limiting block 42 slides out of the corresponding limiting ring groove 33; the corresponding second limit spring 43 is restored; when the culture dish 23 stacked on the base 3 is vertically placed on the bottom surface of the incubator again, the first stopper 14 in the base mechanism 1 and the second stoppers 42 in all the culture dish mechanisms 2 slide out of the corresponding stopper ring grooves 33 and release the restriction of the corresponding liner rings 31.

In conclusion, the invention has the beneficial effects that: the base 3 and the culture dish 23 stacked together are dumped together when shaking, so that the phenomenon that the culture dish 23 scatters is avoided, and the glass container is prevented from being damaged due to scattering and collision; in the transportation process, the culture dishes 23 which are overlapped together save the space of the incubator to a certain extent, and the possibility of increasing the transportation number of the culture dishes 23 is provided; meanwhile, the sealing effect of the sealing cover 26 prevents the culture liquid from spilling out when the culture dish 23 overturns, thereby avoiding unnecessary loss and waste.
