For example, the second ball 173 may be coupled at equal intervals with respect to the contact surface of the second ball holder 175 .

In this state, when the driving unit 190 operates to wind the second holding line 177 , the attractive force is transmitted to the second ball holder 175 and the curved portion 175a of the second ball holder 175 is moved to the second holding line 177 . The movement of the second ball 173 may be fixed by uniformly pressing the surface of the ball 173 . Conversely, when the operation of the driving unit 190 is stopped or acts in the opposite direction, the tension acting on the second holding line 177 is released, so that the second ball holder 175 loses the force for pressing the second ball 173 . At this time, the second ball 173 can freely move relative again. Tension may be simultaneously applied to the first holding line 167 and the second holding line 177 according to an embodiment, or tension may be applied at this time.
