There is a lever on both sides of the manipulator, and the connecting points on both sides are the fulcrum of the lever. When there is no pull handle, the rubber band provides an elastic resistance, forcing the manipulator to open. When the handle is pulled, it will give the manipulator rotation power, and it can be closed and clamped.
