A horizontal beam has afront end and a rear end mounted on the upper portion of the tubular seat. A hookmember is mounted on the front end of the horizontal beam. A rotary shaft is disposedrotatably in the axial hole and has an upper end and a lower end that extends out of thetubular seat and that has a roller mounted thereon. An operating member includes athreaded shank which has a lower section that extends threadedly into the axial hole viathe internally threaded top section of the tubular seat and that is coupled to the upperend of the shaft. The tubular seat is movable upward or downward relative to the shaftupon rotation of the threaded shank so as to permit raising or lowering of the wall formassembly relative to the floor to facilitate adjustment of a position of the wall formassembly on the floor.
