Abstract
The invention discloses a full-automatic electric pencil sharpener. The full-automatic electric pencil sharpener comprises a hobbing cutter (1), a pencil stopping block (2), a transmission shaft (3), a trigger slider (4), a clutch gear (5), a delayer (6), a start switch (7), a stop switch (8), a planetary reducer (9), a motor (10), a shell (101) and a power interface (12). When the full-automatic electric pencil sharpener works in the using process, the hobbing cutter and the trigger slider move downward to trigger the start switch, the motor drives the planetary reducer, the transmission shaft and the hobbing cutter to rotate, and thus a pencil can be automatically sharpened. When a pencil point is formed, the tip of a refill triggers the pencil stopping block to push the clutch gear downward to be meshed with the delayer and drive the delayer to trigger the stop switch, and then the pencil is stopped from being sharpened automatically. From the time when the clutch gear is meshed with the delayer to the time when the stop switch is triggered, because the pencil point is not fed downward, the hobbing cutter rotates without loads to polish the pencil point, and the pencil can be automatically polished. When the refill is broken, the pencil is drawn out and then inserted into the pencil sharpener again, the broken refill is automatically minced by the hobbing cutter which is started again, and thus the electric pencil sharpener achieves the functions of automatically sharpening the pencil, stopping sharpening, polishing the pencil and processing the broken refill.
