ABSTRACT:
A portable workbench having a top surface including two vise members, one of which is connected to the supporting structure by a pair of releasable gripping devices which enables the vise member to move, in the plane of the support provided by the underlying support framework, toward the other vise member in a rectilinear motion and also in a rotational motion relative to the second vise member. One or the other of the vise members is also connected to the supporting framework by a pair of vise-operating devices which can be operated to exert a force for moving the vise member a small incremental distance toward the first vise member under force to effect the clamping action. A folding leg structure is provided to support the top surface at convenient working height above the floor.
