  • Publication number: 20230256771
    Abstract: An electric pencil sharpener with delay function includes a motor, a drive assembly, a gear assembly and a cutter assembly. The drive assembly includes a connecting rod, a drive shaft and a start trigger, a stop trigger, and a thrust plate. The connecting rod is moved backward to drive the start trigger to trigger the motor, and synchronously rotated with the cutter assembly; the stop trigger is provided with a teeth structure and a friction structure respectively. The thrust plate is rotated or moved to push against the drive shaft, so that the connecting rod continues to move backwards until the bulge portion engages with the teeth structure, and the ring portion matches with the friction structure, thereby actuating the stop trigger to move to trigger an action of the stop switch of the motor.
