摘要

Blocking device for extensible rods, characterized by comprising an externally threaded ring, arranged to fit on the outer tubular segment integral of the extensible rod, and be conveniently immobilized with respect to it, from which ring are capable of legs deformable elastically under the action of a piece that has an internal cylindrical threaded area, arranged to fit over the said ring and a frustoconical area arranged to act on the legs indicated, forcing them to tilt in convergent directions, all in such a way that it is enough to screw the expressed piece to the bottom. Determine the deformation of the legs, so that the suitably shaped extremities of the same, penetrate by corresponding windows made in the outer tubular segment of the system and press on the inner tubular segment, immobilizing it in the position that in each case has been chosen, and it's enough repeated cleaning so that the expressed legs resiliently recover their initial position, releasing the inner tubular segment and leaving it ready to slide axially.
