摘要： A workpiece support structure includes a pair of elongated beams supported in transversely spaced parallel relation by first and second foldable leg structures. A first clamp mechanism on the first leg structure supports a first transversely extended guide member. A second transversely extended guide member is carried on a pair of trolley wheel clamps equipped with disengageable clutch mechanisms for fixing the trolley wheel clamps at selected positions on the beams. Thus the second guide member is longitudinally movable to engage a workpiece between the first and second guide members whereupon the first clamp mechanism is applied to clamp the workpiece therebetween. The disengageable clutches of the trolley wheel clamps are interconnected by a transverse actuator rod so that the clutches are easily simultaneously operated by one hand of a worker. A novel toggle clamp includes a slide block for slidably supporting the plunger thereof on the adjacent beam and a slack adjustment screw for limiting the release stroke of the clamp.
