ABSTRACT:
A revolving shaft controlled movable lamp stand, which includes a stand, a driving mechanism, and a lamp socket, and is characterized in that: the lower revolving shaft and the upper revolving shaft and the driving mechanism each comprises a circular groove and a hole. Each said hole comprises an end a and an end b. A rope is provided to wind round the upper and lower revolving shafts through the holes and circular grooves of the upper and lower revolving shafts, to further let one end of the rope, which comprises a screw rod, be screwed up with the other end of the rope, which comprises a fastening matching means, so as to form a closed circulation. By means of vertical displacement of the holder of the driving mechanism, the lower revolving shaft is driven to produce angular displacement to drive the upper revolving shaft, by means of the rope, to make a synchronous movement, so as to further let the upper revolving shaft drive the driven rod to displace vertically and to change the projecting position of the illuminator.
