Patent abstract
An automatic pencil sharpener has a plurality of different sizes of pencil selector openings in a front side of a pencil selector panel, and an annulus groove at the back side of the pencil selector panel for mounting the trigger. Accordingly, the pencil inserted into the pencil receiving opening will keep a constant distance with the trigger switch, regardless of the sizes of the pencil inserted, thereby smoothing the pencil operation in the device.
