The feeding subassembly includes a feeding gear set coupled to the transmission subassembly and two feeding rollers adapted to sandwich a pencil to be sharpened, at least one feeding roller is driven by the feeding gear set. The pair of brackets is arranged in parallel, respectively defining slide ways to movablely support the feeding rollers. A feeding space is defined between the two brackets. The at least one resilient adjusting means connects the two feeding rollers outside or inside the feeding space, adapted for keeping the feeding rollers nipping the pencil and engendering a pencil feeding friction.
