Extendable support for lamps, which is characterized by two reciprocally displaceable concentric tubes in axial direction, one of which, specifically the exterior, or envelope, is fixed and belongs, depending on the case, to the foot or canopy that supports the lamp, while the inner tube carries, in its seen end, the screen of the same, carrying the hidden end a body that is diametrically crossed by two holes arranged between each other at an angle of ninety degrees, located in a different plane and housing two coil springs whose ends press on buttons whose heads, of rounded surface, are applied against the interior of the surrounding tube that supports the general weight of the lamp, being the pressure provided by said buttons enough to maintain in a fixed and stable position the inner tube that supports the screen, but said pressure allows frictional displacement of said inner tube, the position of the latter can be varied at will with respect to the outer tube that serves as a sheath.
