Abstract: A device to hold and position implements, workpieces and tools has a console (1) with a support arm (2). A first end region (3) on the support arm (2) is arranged to receive a hinge joint arrangement (4) that can be connected to an implement holder (5). The hinge joint arrangement (4) defines two hinge axes (11, 14) that are offset by 90°. A positioning device (100) for the adjustment of an implement, workpiece (105) or tool, by shim technology and clamping, is associated with the console. The positioning device (1000 has a foot part (101) and a flange part (102) to hold the implement, workpiece (105) or tool. The implement holder is precisely adjusted in three planes or axes within an extremely restricted space to positionally fix an implement, workpiece or tool.
