Abstract: An electric pencil sharpener includes a power device. The power device is connected to two rotatable rubber wheels by a transmission mechanism. The two rubber wheels are located on two sides of the pencil to be sharpened, are rotated in opposite directions and closely fit a side wall of the pencil to be sharpened, to push upwards or downwards the pencil to be sharpened to move. A gap between the two rubber wheels is adjustable. The electric pencil sharpener further includes a rotatable cutter carrier assembly located below the rubber wheels configured to sharpen the pencil to be sharpened. The electric pencil sharpener can sharpen the pencil of different diameters, and has a sharpening process requiring no human participation, has a wide application and saves manual operation.

Abstract: An electric stapler includes a base and a press portion articulated to the base. The press portion is provided with, from down to up, a staple channel assembly configured to receive a staple, a staple pressing plate assembly configured to press the staple and a drive assembly in sequence. The position of the drive assembly is fixed relative to the press portion. The staple channel assembly and the staple pressing plate assembly are rotatable relative to the press portion. The drive assembly includes a power unit and an execution component connected to the power unit to press or raise the staple pressing plate assembly. The above electric stapler addresses the technical issues that the staple channel cannot reset automatically after the staple is stuck and it is difficult to clear away a failed staple.

Abstract: A fully-automatic pencil sharpener is provided according to embodiments of the present application, which may avoid the problem of the pencil being overly sharpened in the conventional electric pencil sharpener, and realize a maximized utilization of the length of the pencil, thus is more economical and environmental friendly compared to the conventional electric pencil sharpener. The fully-automatic pencil sharpener according to embodiments of the present application includes a pencil-pushing module, a pencil-sharpening module, a power module, a detection module, a control module and a housing. The pencil-pushing module is adapted to push a pencil to a preset position, for example pushing the pencil to the pencil-sharpening module when the pencil is placed in the pencil sharpener, and pushing the pencil out of the fully-automatic pencil sharpener when the pencil has been sharpened.

Abstract: An embodiment of the present application provides a staple-ejecting type stapler, which can use an energy storing and energy releasing assembly to store energy by means of the lever principle and to generate an elastic force by releasing the elastic potential energy. Under the action of the elastic force, a staple driver pushes a staple to pierce through paper, and legs of the staple are bent by an anvil plate, thereby realizing the binding function in a convenient and labor-saving manner.
