There is further provided a slide track receiving one of the joints for guiding it upon pivotal motion of the levers and a locking mechanism mounted on the carriage and cooperating with the linkage assembly. The locking mechanism has a released position permitting a pivotal motion of the levers and a locking position immobilizing the levers of the linkage assembly with respect to one another.
