ABSTRACT:
A desk lamp, which comprises of a rod support connected to a stand through a spring, a toothed block and a swivel member to hold a lamp. The swivel member has a bottom projection set in an interrupted circular grooved on the top of the stand and confined to rotate within the range defined by the two stop edges of the two ends of the interrupted circular groove such that the lamp is confined to rotate horizontally within an angle less than 360.degree.. The engaged position of the toothed block with the swivel member can be changed so as to simultaneously adjust the angular position of the lamp and the rod support relative to the stand.
