Abstract
Improvements in the expandable mandrels, which have blocking slides that move radially during the maneuver of the device, characterized in that their slides are arranged in the radial shrouds of a cage mounted sliding on the end of the shaft of said mandrel, which has a conical ramp in contact with the slides of the block, this mandrel also having a stop stop of the piece to be fixed as well as a maneuvering member that allows to control the sliding of the mobile cage in order to cause radial displacement of the slides of blockage, and consequently, the expansion of the mandrel.
