A packaging box comprises a bottom plate, a front side plate and a rear side plate which are connected to the bottom plate, base plates connected to the left and right ends of the rear side plate, first flaps connected the lower ends of the base plates, and second flaps connected to the left and right ends of the front side plate. The first flaps are superposed on the bottom plate when the rear side plate is perpendicular to the bottom plate. When the front side plate is perpendicular to the bottom plate, the second flaps make contact from above with the first flaps superposed on the bottom plate, and this causes the second flaps and the bottom plate together to sandwich the first flaps. |
