Claims

[Scope of utility model registration request]

A workpiece receiving part 2 with a workpiece fitting part 1 formed at the tip thereof is provided at the front part of the main body 3, and a bearing part 4 is provided at the rear of the main body 3 in the direction of the central axis of the workpiece receiving part 2. A movable tube 5 is provided so as to be freely movable back and forth, a movable plate 6 is attached to the front part of the movable tube 5, and movable rods 7 are provided at equal intervals at a plurality of locations on the periphery of the movable plate 6 so as to be movable back and forth. A pulling device 8 is provided to constantly pull the movable rod 7 backward, and the tip end 7' of the movable rod 7 is made to protrude from a guide hole 9 provided in the main body 3 so as to face the outer periphery 2' of the work receiving part 2.
