Abstract: The helically threaded spindle (5) of the vise is arranged in an inclined fashion in the movable jaw (3) and is held in a pivotable as well as axially fixed manner. The spindle nut (7) is displaceably guided in a longitudinal recess (9) of the bed (1), is spring-loaded in the direction toward the fixed jaw (spring 18), and is provided with a cross pin (17). The cross pin (17) is adapted to be anchored in a series of downwardly open slots (20, 21, 22) rectangular in cross section. Upon tightening the previously released spindle (5), the pin (17) slides to the subsequent slot (21) and engages therein, whereupon the horizontal component of its obliquely upwardly direction movement pushes the movable jaw (3) forwards for clamping the workpiece (4).
