• elastic means (53), placed between the sliding element (52) and the container (51), so that the elastic means (53) exert an elastic force on the sliding element (52) suitable to make it slide, reacting on said container (51),
• a track (40), placed on one side of the sliding guide (60, 90), with surface of the bottom defining a cam path and the plan layout of which forms a closed geometrical figure,
• tappet means (73), integral with the sliding element (52), suitable to travel along the cam path, so as to define a number of positions of the sliding element (52), corresponding to a release position, a lock position and two intermediate opening and closing positions of said movable part (58),
