Such mechanism has an essentially cylindrical shape and is driven by a water-driven motor (2) preferably provided with demultiplier. In order that the user can vary the excursion of the shift of the nut screw, two adjustable limit stops (8) are provided which are capable of interacting with a control lever (9) for reversing the movement.
