An adjustable support stand is used for adjusting a height of a device, the device containing a housing and a cavity in the housing. The support stand includes a ratchet casing for moving along a linear direction within the cavity of the housing, and a ratchet disposed inside the ratchet casing. The ratchet includes teeth and a protruding edge for limiting the ability of the ratchet to move in a linear direction, wherein the protruding edge moves between an inner end and an outer end of the ratchet casing. The support stand also includes a pawl for engaging the teeth of the ratchet, the pawl being connected to the housing at a pivot point for fixing the pawl to the housing and allowing the pawl to rotate about the pivot point. A base is formed on an outer end of the ratchet for supporting the device on a surface.
