Claims

[Scope of utility model registration request]

A fixed electrode, a movable electrode base provided at a position away from the fixed electrode, and a movable electrode base provided on the electrode base so as to be movable in the axial direction and whose tip faces the fixed electrode at a distance from the fixed electrode. a movable electrode capable of holding an object to be chucked; a movable electrode provided on the electrode base and movable between a first position closer to the fixed electrode and a second position farther from the fixed electrode; At the position shown in FIG.
a manual end fitting for retracting the movable electrode to a distance at which an object to be chucked can be inserted between the electrodes; a spring for biasing the movable electrode toward the fixed electrode; and a spring connected to the movable electrode. and an unloading actuator capable of retracting the movable electrode to a position where the object to be chuck is separated from between the electrodes.
