A pencil sharpener assembly comprising a frame and a blade, the blade having an elongated sheet shape, one side of the blade being disposed with a blade edge, the frame being disposed with a pencil chamber, the blade being disposed along an axial direction of the pencil chamber and the blade edge of the blade being located in the pencil chamber, the blade being made of a ceramic material, the frame being disposed with a first positioning groove and a second positioning groove, the first positioning groove and the second positioning groove being oppositely disposed, a first end of the blade being inserted into the first positioning groove, and a second end of the blade being inserted into the second positioning groove. It has the advantages of being applicable to ceramic-made blades and the blade is not easy to fracture.

Disclosed is a self-adaptive pencil feeding mechanism, including: a base, a first pencil feeding assembly, and a second pencil feeding assembly. The first pencil feeding assembly and the second pencil feeding assembly are mounted in the base and are capable of moving to the left or to the right, and the base is connected to a guiding member via an elastic member. The guiding member drives the first pencil feeding assembly and the second pencil feeding assembly to synchronously approach each other inwardly, and the first pencil feeding assembly and the second pencil feeding assembly, when a force caused by insertion of a pencil is applied thereto, are driven by a driving member to synchronously expand outwardly. The self-adaptive pencil feeding mechanism is capable of adapting to pencils of different diameters.

An illustrated view of an exemplary pencil sharpener for sharpening pencils is presented. The pencil sharpener is useful for sharpening one or more pencils during a single event. Also, the pencil sharpener is useful for storing one or more pencils in a convenient location to be sharpened immediately or at other determined times and intervals

An assistive device to promote the development or recovery of writing and drawing capabilities of a user. The device includes an elongated body having an outer surface and an inner channel for insertion of a writing instrument; a first positioning part forming a loop extending from the outer surface of the elongated body through which a thumb of a user may be inserted; a second positioning part forming a loop extending from the outer surface of the elongated body through which an index finger of a user may be inserted; and a third positioning part forming a loop extending from the outer surface of the elongated body through which a middle finger of a user may be inserted, wherein the first, second, and third positioning parts are arranged such that a user's thumb, index finger, and middle finger form a tripod grasp about the elongated body.

The present invention provides a sharpening completion detection mechanism that does not apply a heavy load to a core tip, and especially proposes a mechanism that moves a pencil in an ejection direction immediately when the sharpening completion detection mechanism detects completion of sharpening to mitigate damage to the core. Specifically, a pencil sharpener according to the present invention includes: a slide unit that translates in pencil insertion and pencil ejection directions; a pencil biasing means supported by the slide unit; a slide locking means that locks a translation position of the slide unit upon the slide unit translating in the insertion direction; and a slide unit unlocking means that releases the lock for the translation position of the slide unit upon the sharpening completion detection means detecting a fully sharpened state of the pencil, and includes slide unit ejecting means that biases the slide unit in the ejection direction with energy stored by movement of the slide unit to a lock position.

A pencil-centering assembly for use in pencil sharpeners or the like that includes a frame; a linking member rotatably mounted within the frame; a plurality of pencil contact levers, wherein each contact lever includes a top portion and a bottom portion, wherein the top portion of each pencil contact lever is adapted to engage the linking member, wherein the bottom portion of each pencil contact lever, in combination with the other pencil contact levers, defines a pencil insertion aperture having a center axis, and wherein the bottom portion of each pencil contact lever extends in to the pencil insertion aperture to about the same distance; and at least one biasing member in contact with the linking member, wherein the biasing member exerts force on each pencil contact lever by way of the linking member sufficient to bias each pencil contact lever toward the center axis of the pencil insertion aperture.

A dual cutter-carrier assembly that includes a rotatable carrier having a front portion, a rear portion, and a center portion, wherein the center portion defines an interior cavity that is adapted to receive a pencil to be sharpened; a first cutter pin mounted on the carrier, wherein the first cutter pin has a front portion having an annular groove formed therein; a first cutter rotatably and slidably mounted on the first cutter pin; a second cutter pin mounted on the carrier, wherein the second cutter pin has a front portion having an annular groove formed therein; a second cutter rotatably and slidably mounted on the second cutter pin; a contact plate mounted within the interior cavity at the rear portion of the carrier, having a first yoke mechanically coupled to the first cutter and a second yoke mechanically coupled to the second cutter, wherein the contact plate moves in the direction of a pencil that is being sharpened when the tip of the advancing pencil touches the contact plate, wherein the first and second yokes move the first and second cutters respectively in the same direction as the moving contact plate; and wherein, as the pencil advances to a predetermined distance through the interior cavity, the first and second cutters are adapted to move outward from the interior cavity and away from the tip of the pencil being sharpened.

One or more apparatuses, computing devices and/or systems are provided. In an example, an apparatus is provided. The apparatus may comprise a sharpener device configured to sharpen a pencil. The apparatus may comprise a hole puncher device configured to punch one or more holes in one or more sheets of paper. The apparatus may comprise an indentation at a corner of the apparatus. The apparatus may comprise a stapler device overlying the indentation. The stapler device may be configured to couple sheets of paper together by driving a staple through the sheets of paper at a point within the indentation. The apparatus may comprise a tray configured to collect shavings from the sharpener device and/or chips from the hole puncher device. The apparatus may comprise a vacuum device configured to apply suction to conduct material (e.g., shavings and/or chips) from the tray.
