Improved top, which is characterized by being constituted by a body of substantially trunk-conical shape topped at its lower end by a flat circular surface and equipped at the top with a cylindrical extension, whose body is traversed longitudinally, coinciding with its axis of rotation, through a hole where an axis is housed at its lower end by a semi-spherical head and at its upper end by a flat head that retains between the upper end of the cylindrical extension and said head a piece pierced by the same axis on which the end of the drive rope is fixed.
