<p>Support for an adjustable lamp having a metal plate (18), which bears on the underside of two rod-shaped conductors (12, 14), an insulating plate (38) being further arranged between one conductor (12) and the metal plate (18), and the top side of the rod-shaped conductors (12, 14) engaging with a metallic yoke (44) which is pretensioned in the direction of the metal plate by means of a clamping device (32), there being arranged between the other conductor (14) and the yoke (44) an insulation which is connected to the insulating plate (38) and in the event of rotation of the metal plate (18) fixes the position of the insulating plate (38) in relation to the metallic yoke (44), and thus in relation to the two fixedly arranged conductors (12, 14), the clamping device (32) comprises a metallic, cylindrical sleeve (52), which has at its lower edge (66) a first shoulder (68) extending inwards, and on its lower external region a second shoulder (70) extending outwards, a pin (30) arranged in the sleeve, and a helical spring (56) which is supported on the upper end of the pin (30) and the first shoulder (68) of the sleeve (52) and is arranged around the pin (30). <IMAGE></p> |
