Cell culture device capable of selecting culture area

The cell culture device capable of selecting the culture area comprises a connecting column and a plurality of culture dishes, and the plurality of culture dishes are configured to be placed in an overlapped mode, are respectively connected with the connecting column in a transverse rotating mode and are connected with the connecting column in an axial sliding mode. A plurality of limiting blocks are elastically connected to the surfaces, at different heights, of the connecting columns in the axial direction, and when the culture dishes move to the heights where the limiting blocks are located, the limiting blocks limit downward sliding of the culture dishes to form a multi-layer culture structure; by arranging the plurality of culture dishes which can be overlapped and can be rotationally separated along the connecting columns, different numbers of culture dishes can be selected for use according to different culture requirements so as to select different culture areas, and the culture dishes can be overlapp
