Then, the diver holds the first hand wheel 5 with both hands and pulls the plug plate 7 to one side through the paddle 27. As a result, the plug plate 7 is pulled to one side on the connecting bolt 28 through the side plate 25, and then the side plate 25 compresses the compression spring 29 to the side of the limit plate 8.
