Claims

[Claims for Utility Model Registration] (1) A grip for a handle wheel, which consists of a worm wheel that rotates a valve stem and a worm shaft that meshes with the worm wheel, and is mounted on the worm shaft with an angle joint. A locking device for a worm gear for opening and closing a valve, characterized in that a locking device portion for engaging the valve is fixedly provided. (S) The locking device according to claim 1 of the utility model registration, characterized in that the handle wheel is pulled out from the worm shaft and turned over to engage the grip in the locking device section. (3) The locking device according to claim 1, characterized in that the grip is movable in and out between the engagement position of the locking device portion and the rotating operation position of the steering wheel. (4) The locking device according to claim 1, 2, or 3, characterized in that the angular joint between the handle wheel and the worm shaft is polygonal on one side. .
