Patent ID: 11992893

Abstract:
When a drive unit 5 drives to rotate a first rotator 6 and a second rotator 7 relative to one another in a first relative positional relationship R1 toward one side, graspers 8 turn toward the one side to cause respective pawl portions 8c to advance into a detachment operation space S1 such that the pawl portions 8c can contact an electrode 10 set in the detachment operation space S1, and when the drive unit drives to rotate the first rotator 6 and the second rotator 7 relative to one another in a second relative positional relationship R2 toward another side, the graspers 8 turn toward the other side to cause the respective pawl portions 8c to advance into the detachment operation space S1 such that the pawl portions 8c can contact an electrode 10 set in the detachment operation space S1.
