PURPOSE:To surely and rapidly position a tool with simple operation by providing, on a positioning member and along a cylinder shaft, plural positioning step parts differing from each other in their projection amounts for each stroke size of a cylinder. CONSTITUTION:A socket 10 is provided on the tip of a clamp tool 1, and clamping operation is executed by turning a nut and a bolt. The tip of the piston rod of a driving cylinder 2 for forcing the tool 1 to move is connected to the tool tip part via a bracket 9. The first and second cylinders 4, 5 are provided in parallel to the tool 1, and a positioning member 6 is provided on the rod tip of the first cylinder 4. The member 6 is equipped with positioning step parts 6a, 6b, 6c differing from each other in the amounts of their projection for each size of the strokes of the cylinders 4, 5, and the projection part 3a of a projecting member 3 is allowed to selectively make contact with each step part, allowing the tool 1 to be positioned at a desired position. |
