A pressure-medium driven tool for cutting, compressing or holding a workpiece (21) includes a frame bar, an anvil (9, 13) firmly mounted on one end of the bar, and an active tool-part (10) which can be moved along the bar towards the anvil. The frame bar is provided with a longitudinally extending channel and the active tool-part (10) includes a bottom part (25) which fits into the channel and which functions to restrain the active tool-part against sideways movement as it moves along the bar. The part of the active tool-part that moves in the channel is provided with at least one through-penetrating hole and each of the channel walls is provided with a respective longitudinally extending guide means (28) opposite the hole. The hole is fitted with a pin (27) whose ends coact with the guide means in a manner to restrain the active tool-part (10) from movement at right angles to its direction of linear movement and to facilitate linear movement of the active tool-part in the channel. |
