The threaded cylinder is guided by a cylindrical sleeve positioned in a casing which houses the mechanism. The pin which is provided with a ball thread and imparting an axial movement to the threaded cylinder when the motor is in operative position, is supported in the casing above the threaded cylinder through axial and radial bearings. The motor for driving the pin is positioned in a lid of the casing.
