Bacterial incubator

The utility model relates to the technical field of microbial culture, and particularly discloses a bacterial incubator which comprises an incubator body and an incubator cover covering the incubator body, a plurality of culture dishes are arranged in an inner cavity of the incubator body at intervals in the length direction, bacteria-containing culture media are contained in the culture dishes, one end of the elastic band is connected to the inner wall of the incubator body, and the other end of the elastic band is connected to the inner wall of the incubator body. The other end is an operation end for a user to carry out stretching operation; the plurality of sampling tubes are arranged on the elastic band in the length direction, and when the elastic band is stretched, the plurality of sampling tubes can be separated from one another, so that each sampling tube is opposite to the corresponding culture dish; the sample receiving drawing box is connected in the inner cavity of the box body and can be partial
