Abstract
This is an articulated jack with two pairs of arms, connecting at one end with a nut (11) and at the other with a bar (12). Both these are in turn connected by a spindle worked by a crank winding handle. The other ends of the arms rotate around a base (1) and a gripping device (2.about.. The outer arms (3, 4) and inner arms (5, 6) are in turn connected by auxiliary parts (18). The actual size of the jack has been considerably reduced.
