Adjustable anchoring mechanism for columns of variable height, characterized essentially by the fact that it comprises a tubular column inside which is mounted telescopically a tube protruding from the column, inside which is housed a plunger that can travel a limited path and is operable from the outside, whose piston is equipped with two annular grooves of different depth, selectively facing a group of balls located annularly in holes of greater diameter made in the wall of the tube, movable with the tube in front of an internal section of the column provided with a succession of grooves in which, selectively, the balls can be engaged when they are facing in the throat of a lower depth of the piston, blocking the mechanism, comprising a spring that pushes the piston towards the blocking position.
