Telescopic support rod and a method of bringing about locking between two tubular elements thereof

摘要

A telescopic support rod. The rod has an inner tubular element and an outer tubular element which are interconnected slidably, wherein the tubular element is fixed by a lock. The lock includes at least one deformable element housed inside the inner tubular element and a control mechanism, inside the rod, for bringing about at least a transverse expansion of the deformable element.
