The Menggongfang automatic advance and retreat pencil sharpener is a hand-operated pencil sharpener with a national patent. Ordinary pencil sharpeners use an 8-flute blade design, but it uses a 12-flute blade design. It is smoother and less labor-intensive to use.
Hold the base of the pencil sharpener with your right hand to keep it stationary. Press and hold the unlock buttons on both sides of the cover without releasing. Pull up to remove the pencil sharpener cover. Turn the pencil sharpener downwards to remove the pencil sharpener inside. See if it’s because something is stuck inside, then dig into the specific cause and prescribe the right remedy.
