Patent ID: 7699082

Claim:
An electric multi-pencil sharpener, comprising: an entering pencil vase that has a pushing mechanism therein; a sending mechanism; a sharpening mechanism for sharpening the pencils; a hustling mechanism for taking the pencils into or out of the sharpening mechanism; and an exit pencil vase having an exit mechanism therein; wherein the pushing mechanism comprises a first motor, a first reduction gear assembly, two clutch boards, a compression spring, a bearing gear, and a shaft mounted to a bearing board; the first reduction gear assembly, the bearing gear, the clutch boards, the compression spring, and the bearing board are engaged with each other to transmit motivity of the first motor to the shaft; an annular slot is defined between the entering pencil vase and the shaft for receiving the pencils; a plurality of pushing arms extend out from a circumference of the shaft, for pushing the pencils to move in the annular slot; the shaft has a cone-shaped surface at an end thereof that is located at an open end of the entering pencil vase thereof; the sending mechanism comprises a second motor, a second reduction gear assembly meshing with the second motor, a first drive gear connected to the second reduction gear assembly, a second drive gear meshing with the first drive gear, a drive shaft connected to the second drive gear, a sending shaft, a plurality of sending wheels, a plurality of wheel shafts, and a plurality of pressing members; the drive shaft passes through a center of the sending shaft, the wheel shafts pass through centers of the corresponding sending wheels and are mounted to the sending shaft via the corresponding pressing members; the sending mechanism is engaged with the pushing mechanism, the hustling mechanism, and the exit mechanism; the hustling mechanism is engaged with the sharpening mechanism; whereby the shaft with the pushing arms of the pushing mechanism pushes pencils to the sending shaft of said sending mechanism, said sending shaft sends pencils to the hustling mechanism or to the exit mechanism, the hustling mechanism sends pencils to sharpening mechanism and takes the sharpened pencils back to the sending shaft, then the sending shaft sends the sharpened pencils to the exit mechanism, and finally pencils enter into the exit pencil vase from the exit mechanism.
