US Patent 7726616 Support stand for flat-panel display monitor

A support stand for a flat-panel display monitor includes a mounting base, a connecting base, and two link shafts. Each link shaft has a first end rotatably connected to the mounting base and a second end rotatably connected to the connecting base. The support stand further includes a restricting pole fixed to the mounting base and positioned between the two link shafts, the restricting pole abuts against the two link shafts, thus restricting a rotary range of the two link shafts.
