A first and a second round cushions are disposed adjacent to a first and a second sides of the hollow upper block, respectively, The first round cushion has a first center hole. The second round cushion has a second center hole. A first bolt passes through the first center hole to fasten the first round cushion on the hollow upper block. A second bolt passes through the second center hole to fasten the second round cushion on the hollow upper block. A longitudinal plate is disposed on a top of the transverse plate. The longitudinal plate has an upper hole to match the corresponding circular hole and a lower hole to match the corresponding curved hole. A first fastening member passes through the circular hole and the upper hole and a second fastening member passes through the lower hole and the curved hole to fasten the lobe and the longitudinal plate together. A first and a second joints are disposed on the first and the second hollow legs, respectively. Each of the first and the second joints has a threaded lower portion inserted in a top interior of the corresponding hollow leg, an annular flange abutting the threaded lower portion, and a top recess to receive the transverse plate. A bevel is disposed beneath the top recess. A notch is formed on a top rim of the first hollow leg. A third and a fourth fastening members fasten the first and the second joints on the transverse plate. The first brace is fastened on a lower portion of the first hollow leg.
