An improved prop characterized essentially by the fact that it consists of five parts coupled in a telescopic arrangement the in- The upper part of which is a pedestal that has a cylindrical neck maintained by reinforcement signs normal to its plane, in which a threaded tube is plugged into its unthreaded half, a handle while a nut equipped with a screw slides on its threaded area. of another handle similar to the previous one, this nut presenting a seat for the lower end of an upper coaxial tube that sleeves on the described threaded stud, comprising this tube giving in the direction of the generatrix a series of holes equidistant and facing other holes typical of a second tube of smaller diameter and which slides axially in the previous one, both blocking each other by means of a common transverse pin and fixing on this end tube the last piece of the strut that is its extreme support head constituted by another tube that sleeves on the last of the aforementioned and that is fixed to it by a pin similar to that described, this tube comprising a transverse crossbeam on its upper base maintained by tips.
