[0027] The working principle of a cell culture device provided by the utility model is as follows: when working, firstly, the mounting holes evenly distributed at the lower ends of the legs 19 are stably connected with the threaded holes in the horizontal working area by bolts, thereby realizing the stable installation of the cabinet 1, the liquid storage tank 12 and other mechanisms. After the installation is stable, the personnel will place the culture dishes 6 containing the cells to be cultured into the placement grooves 5 in sequence, and the lower ends of the culture dishes 6 push the clamping plates 44 to move away from the center of the vertically adjacent placement grooves 5. The clamping plates 44 move towards each other, causing the telescopic ends of the longitudinally adjacent telescopic columns 42 to contract, and at the same time, the longitudinally adjacent springs 43 are elastically compressed. Under the elastic force of the springs 43, the longitudinally adjacent The clamping plate 44 stably clamps the lower ends of the vertically adjacent culture dishes 6, and the middle parts of the culture dishes 6 push the elastic clamps 45 to move away from the center of the vertically adjacent placement slots 5.
