The second elongated plate has a second connected end, a second hinged end, and a second elongated body which is disposed between the second connected and hinged ends, and which has a second inner surface formed with a second grooved region. The second hinged end is hingedly connected to the first hinged end about a hinge axis to permit the second connected end to be angularly movable relative to the first connected end between an unfolded position, where the first and second elongated bodies form an included angle therebetween, and a folded position, where the first and second elongated bodies are stacked on each other to permit the first and second grooved regions to define therebetween an accommodation space. The corner bracing member extends lengthwise to terminate at a coupling end, and a mounted end which is pivotably mounted to the first proximate end about a pivot axis parallel to the hinge axis, such that when in the unfolded position, the coupling end is permitted to be detachably coupled to the second inner surface to keep the included angle, and such that once the coupling end is detached from the second inner surface, the corner bracing member is permitted to be fit in the accommodation space. Two of the foldable frames are coupled to each other to form a front sub-assembly, while the other two of the foldable frames are coupled to each other to form a rear sub-assembly. The second connected ends of the front sub-assembly are detachably connected to each other, and the second connected ends of the rear sub-assembly are detachably connected to each other. The first connected ends of the front sub-assembly are detachably connected to the first connected ends of the rear sub-assembly, respectively.
