Abstract: The present invention relates to a valve handle for preventing a valve from being accidentally turned on. In the preferred embodiment of the present invention, the valve handle comprises a fixing ring which mobilizes the valve stem, so as to drive the stem up and down, the fixing ring having at least one stopper; and the valve handle has a knob housing that covers and mobilizes the fixing ring, and has at last one protrusion having a first perpendicular plane and a slant plane. The slant plane and the perpendicular plane work with the stoppers on the fixing ring to ensure that the valve can be easily closed but is difficult to open.
