Abstract (en)
A device for the quick blocking and releasing of tubolar handles with sectional portions A and B, consisting in an insert 2 with a spiral-shaped extension, axially and rotatory bound to the end of rod A, in which a tapered portion 6 in the shape of a truncated cone and outwardly threaded 7 is provided, on which an expansible bush 10 is screwed, the outward surface thereof being able to adhere to the inner wall of rod B, so as to get rotatory engaged with the same and determine, with the rotation of the first rod and the screwing of the bush, the consequent expansion thereof due to the widening action performed by the conical portion of the insert against the inward part of the truncated-cone shaped bush and the consequent blocking of the rods.
