The first linking rod includes a lower segment, an upper segment and an intermediate segment that is formed with a slot. The slot and the upper and lower segments of the first linking rod are disposed on a common vertical plane. The lower segment has a lower end mounted pivotally on an adjacent tubular sleeve. The second linking rod has an upper end mounted pivotally on the upper end of an adjacent leg member, a lower end, and an intermediate portion extending through the slot of the first linking rod, and is pivoted to the intermediate segment about a horizontal pivot axis. The pivot unit includes an upper pivot connector connected pivotally to upper ends of the upper segments of the first linking rods, and a lower pivot connector connected pivotally to the lower ends of the second linking rods.
