Abstract
PURPOSE: Easy locking and unlocking is possible even though the hole in both sides of workingpiece is small and workpiece is supported for increasing its rigidity. By doing so, character mark produced by workpiece vibration at machining time can be avoided.
CONSTITUTION: A hole 2 is installed in both sides of a thin hollow cylindrical workpiece and a supporting jig 3 is set in its inside. And in the inner circumference of a workpiece 1, a contact element 5 placed radially in plural number in a supporting tube 4 is installed. In the plural numbered one pair of a link 6, a apring material, e. g., an endless coil spring 20, which gives shrinking force to axial direction of the tube 4 is incorporated to all link 6. And a control material 16 is fixed by means of a pin 17 in the tube 4 and a roller 12 of one side of a pair of the link 6 touches with a control part 18 herein formed. An operating rod 13 is inserted and supported in axial direction of the tube 4 facilitating its forward and backward movement.
