Each of the second support members has a slot defined therethrough. Two first rods are retractably received in the two second support members and each of the first rods is connected to a connection frame. One of two ends of each of the connection frames extends through the slot of the second support members. A second top is supported on the two connection frames. A second transverse bar is connected between the two first rods and two second legs are respectively connected to the second transverse bar. Each of the two second legs has a wheel connected thereto. Two sleeves are respectively connected to the two connection frames and two second rods are retractably received in the two sleeves. A third top is supported on the two second rods.
