The support stand includes a base, a rotatable bracket, a first hinge assembly and a second hinge assembly. Both the first hinge assembly and the second hinge assembly connect the rotatable bracket with the base. The first hinge assembly has a first pivotal shaft. The second hinge assembly has a second pivotal shaft. The first pivotal shaft is non-rotatably engaged with the second pivotal shaft, and aligned in a substantially straight line.

What is claimed is: 1. A support stand, comprising:a base;a rotatable bracket;two parallel first connecting members;two parallel second connecting members;a first hinge assembly; anda second hinge assembly;wherein both the first and second hinge assemblies together with the two first connecting members and the two second connecting members connect the rotatable bracket with the base; the first hinge assembly has a first pivotal shaft and a restricting member sleeved on the first pivotal shaft; the second hinge assembly has a second pivotal shaft and a restricting member sleeved on the second pivotal shaft; the first pivotal shaft is non-rotatably engaged with the second pivotal shaft, and aligned in a substantially straight line;wherein two restricting protrusions are coplanarly formed on opposite sides of each restricting member; one restricting protrusion resists the first connecting member, the other restricting protrusion resists the second connecting member, thus defining a rotating angle range of the rotatable bracket.
