PURPOSE: The trip-hook of a vacuum interrupter manipulator is provided to prevent a bounding phenomenon in order to eliminate malfunction by fixing a buffer supporting rod to a supporting stand for the buffer supporting rod. CONSTITUTION: The supporting stand(870) for a buffer supporting rod(810) is installed one side of a vacuum interrupter manipulator. The buffer supporting rod passes through the supporting stand and vertically moves. An elastic spring(820) is installed at the outer circumference of the buffer supporting rod and absorbs the impacts of a trip-hook(510). A spring cam(830) supports the elastic spring. A spring cap supporting part(840) is interposed between the lower side of the spring cam and the supporting stand. A nut supports the buffer supporting rod to be fixed to the supporting stand.
