ABSTRACT:
A vertically adjustable carrier for a vise or the like comprises a vertical support tube which is guided in a clamping device comprising two semicylindrical shells which can be clamped together. The shells are connected on one side by two support elements arranged vertically one below the other, and on the other side there is provided a clamping screw which is arranged between the horizontal planes through the support elements. By such arrangement a great resistance against unintended turning of the support tube even with a relatively slight tightening of the clamping screw is obtained.
