A support stand includes a mounting assembly mountable on a table top, a suspension arm coupled to a rod member of the mounting assembly to hold a rotary barrel, a swinging arm pivotally connected to the rotary barrel of the suspension arm, a stretcher mounted in a frame bar of the swinging arm and a holder frame assembly coupled to the swinging arm to support an object. The stretcher includes a sleeve coupled to arched sliding slots of the frame bar of the swinging arm by a pivot pin, a connection frame plate pivotally coupled between the pivot pin and a mounting lug at the rotary barrel, a spring member and an adjustment screw assembly mounted in the sleeve for allowing adjustment of the elevation of the supported object with less effort and positive positioning of the supported object after an elevation adjustment.
