Universal and multifunctional sampling box with heat preservation function

The invention relates to a universal and multifunctional sampling box with a heat preservation function. The sampling box comprises a box body. A heat preservation cavity is arranged in the box body.One side of the box body is opened and communicated with the heat preservation cavity. The box body is slidably connected with a supporting plate used for placing a reagent bottle. The supporting plate is provided with a clamping device for clamping the reagent bottle. A heat preservation door is fixed to one side, far away from the box body, of the supporting plate. The heat preservation door cooperates with the opening of the box body. A temperature adjusting system for adjusting the temperature in the heat preservation cavity is arranged in the box body. According to the universal and multifunctional sampling box with the heat preservation function, the box body is provided with the heat preservation cavity, and the reagent bottle in the heat preservation cavity is in a constant temperature environment, so that
