An electric multi-pencil sharpener includes an entering pencil vase, a sending mechanism, a hustling mechanism, a sharpening mechanism, and an exit pencil vase. The entering pencil vase includes a pushing mechanism for pushing pencils. The hustling mechanism is for clamping pencils to take the pencils into or out of the sharpening mechanism. The sharpening mechanism is for sharpening the pencils. The exit pencil vase has an exit mechanism. The sending mechanism connects the pushing mechanism, the hustling mechanism, and the exit mechanism, to move the pencils from the pushing mechanism to the hustling mechanism and move the pencils sharpened by the sharpening mechanism to the exit mechanism.

What is claimed is: 1. 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. 2. The electric multi-pencil sharpener as claimed in claim 1, wherein at least two axial receiving slots are defined in a circumference of the sending shaft, each for receiving a pencil, the sending wheels are mounted in the corresponding receiving slots via the pressing members. 3. The electric multi-pencil sharpener as claimed in claim 2, wherein an orientation switch is mounted to the sending mechanism, the sending mechanism is connected to a switch pusher, a protrusion according to the axial receiving slots of the sending shaft extends from the second drive gear for pushing the switch pusher to trigger the orientation switch. 4. The 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 hustling mechanism comprises a hustling wheel, a stationary shaft passing through a center of the hustling wheel, a drive gear assembly, a gear shaft assembly passing through the drive gear assembly, and a drive gear meshing with a gear of the drive gear assembly to drive the stationary shaft and the hustling wheel to rotate, the hustling wheel positively and negatively rotates via the drive gear assembly; 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 pushing mechanism pushes pencils in said entering pencil vase to said sending mechanism, said sending mechanism sends pencils to said hustling wheel of the hustling mechanism or to the exit mechanism, the hustling wheel sends pencils to sharpening mechanism and takes the sharpened pencils back to the sending mechanism, then the sending mechanism sends the sharpened pencils to the exit mechanism, and finally pencils enter into the exit pencil vase from the exit mechanism. 5. The electric multi-pencil sharpener as claimed in claim 4, wherein the hustling mechanism further comprises two torsion springs each fits about a corresponding end of the stationary shaft, for clamping the pencils and making the pencils centering. 6. The electric multi-pencil sharpener as claimed in claim 4, wherein two covers are mounted to opposite sides of the hustling wheel. 7. The electric multi-pencil sharpener as claimed in claim 2, wherein the exit mechanism comprises a poking shaft, a cover, and a spring located between a corresponding end of the poking shaft and the cover, a plurality of poking teeth protrude from the poking shaft, a plurality of annular guiding slots are defined in the circumference of the sending shaft, for slidably receiving the corresponding poking teeth of the poking shaft. 8. The electric multi-pencil sharpener as claimed in claim 1, further comprises a detecting mechanism, wherein the detecting mechanism comprises two opened electrode springs, the electrode springs form a short circuit when the electrode springs are touched by a metal shell at an end of a pencil, to start the second motor of the sending mechanism and send the pencil that is not sharpened into the exit pencil vase via the exit mechanism. 9. The electric multi-pencil sharpener as claimed in claim 1, further comprises a detecting switch that detects whether a pencil rotates to a corresponding position of the sending shaft and reaches a determined length or not, wherein the detecting controls the sending shaft to rotate or not according to the detecting results. 10. The electric multi-pencil sharpener as claimed in claim 1, further comprises a rotatable cover at a bottom of the sharpening mechanism, for conveniently replacing a cutter subassembly of the sharpening mechanism.
