Claims

[Scope of utility model registration request]

A plurality of holding claws 4 for holding the core tube 5 are embedded in the circumferential surface of the hollow outer shaft 8 so as to be movable in the radial direction, and a mechanical or pneumatic forward/backward movement mechanism provided within the outer shaft 8 is used. A core tube holding adapter used for a core tube holding shaft 1 in which a core tube 5 inserted into the outer shaft 8 can be attached and detached by advancing and retracting the plurality of holding claws 4, and the concentric tube holding adapter It can be attached to and detached from the holding shaft 8,
and a groove 22 that can be fitted in the same phase as the holding claw 4.
Furthermore, an adapter holding claw 27 is movably mounted in the radial direction in an elongated hole 24 formed in the adapter main body 20 corresponding to the holding claw 4, and is engaged with the adapter holding claw 27. A matching elastic ring 26 is fitted onto the outer circumferential surface of the adapter body 20, and as the holding claw 27 moves back and forth, it moves back and forth following the adapter holding claw 27, making the core tube detachable. Core tube holding adapter.
