Abstract
Improved expanding head, characterized in that it is constituted by an anilo nut, which by means of an internal thread spiked to the actuating tool and which determines an inner flange that together with an upper part, crossed by a central hole, delimits an annular throat, in which accommodates an enlarged base of a cylinder, formed by a series of portions or segments, this housing being established with sufficient play to allow, in the operative phase, the radial expansion of these segments against a toroidal spring housed in a throat peripheral of said widened base, epro without the possibility that the set of segments, once determined, can be detached involuntarily from the nut ring, thus forming all of them a perfect unit of constituent assembly of the head recommended.
