Patent ID: 7726365

Claim:
An electric pencil sharpener comprising: a motor; a transmission subassembly driven by the motor; a feeding subassembly comprising a feeding gear set comprising a crown gear operatively coupled to the transmission subassembly; a cluster gear operatively coupled to the crown gear; and a feeding gear operatively couple to the cluster gear and supported by a first feeding shaft; and a first feeding roller and a second feeding roller adapted to sandwich a pencil to be sharpened, wherein the feeding gear and at least the first feeding roller are supported by the first feeding shaft and the second feeding roller is supported by a second feeding shaft; a pair of brackets arranged in parallel to each other and defining a feeding space therebetween for insertion of the pencil to be sharpened, wherein each of the brackets comprises a pair of hollow, symmetric and arc-shaped locomotive slide tracks; and wherein the first feeding roller and the second feeding roller are movably mounted on the pair of brackets through the first feeding shaft and the second feeding shaft, respectively, inserted into said slide tracks; at least one resilient adjusting means connected to an end of the first feeding shaft with an end of the second feeding shaft, located either outside or inside the feeding space, and adapted to keep the feeding rollers nipping the pencil and engendering a pencil feeding friction, wherein said at least one resilient adjusting means is a spring connecting the first feeding shaft and the second feeding shaft that are mounted on the same bracket; and a cutter subassembly operatively driven by the transmission subassembly and connected with the feeding subassembly, wherein the cutter subassembly corresponds to the feeding space, so that the pencil to be sharpened can be inserted through the feeding space and then reach the cutter subassembly.
