A telescopically adjustable support is described, in particular a photographic tripod having at least two parts which can slide infinitely one inside the other, such as tubes, shaped rods or the like and having at least one clamping device for friction-type connection of these parts, the one, so-called first part, having at its one end a rotationally solid threaded bolt joined to this part, and the clamping device being constructed from several components and being designed as a thrust body, and also this clamping device, on relative rotation between the two parts, triggering a friction-type positive fit between these. |
