Each of the universal wheel assemblies includes a base and two retaining walls extended therefrom to define a retaining cavity for fittedly coupled with the one of the bottom corner portions of the object, so as to substantially support the object on the universal wheel assemblies in a movable manner. The connecting device comprises at least one elongated element, connected to each of the universal wheel assemblies to define a supporting boundary within the universal wheel assemblies.
