After the adjustment is completed, hold one end of the rotating handle tightly with your hand to ensure that the rotating handle will not rotate. Then press the surface of the rotating handle with the thumb of the other hand, and place the index finger on the cylindrical protrusion of the positioning nut. With the thumb as the center of rotation, use the index finger to rotate the positioning nut, and fasten the positioning nut to the surface of the base plate, thereby fixing the rotating handle.
