A pencil sharpener includes a frame, a drive mechanism, a transmission mechanism, a cutting mechanism, and a pencil-core adjustment mechanism. The pencil-core adjustment mechanism is constituted of a core stopper shaft, an elastic body, and a core adjustment switch constituted of electrode plates aligned in parallel. A pencil inserted into the cutting mechanism presses against and turns ON a switch provided in the drive mechanism to transmit power from the electric power supply unit to the drive device, thereby operating the cutting mechanism via the transmission mechanism to sharpen the pencil. When the pencil is pressed against the upper end of the core stopper shaft, a disk of the core stopper shaft contacts and pushes down one end of the longer electrode plate to separate the projection of the longer electrode plate from the shorter electrode plate, thereby turning OFF the core adjustment switch.

The slide cover is slidably mounted on the front of the base. The drawer is slidably mounted in the chamber of the base and selectively extends out of the chamber through the opening of the base. The transmission device is mounted inside the chamber, connects to the slide cover and the drawer and selectively ejects the drawer out of the base when driven by the slide cover. With the transmission, operating the cosmetic container is simple and convenient.

A sharpening device for a carpenter's pencil. A housing has a pivotable guide with a cruciform passage to receive the pencil in either of two positions. A pair of oppositely directed blades are mounted on opposed walls within the housing. The pencil is pivoted while sliding it through the guide to obtain a selected sharpened profile on the end of the pencil.

An electric pencil sharpener is accommodated in a front part of a lower housing. An electric stapler is accommodated in an upper housing including a shared surface that is used as a top face of the lower housing, as its bottom face. A power transformer for supplying DC power to the electric stapler is arranged in a rear part of the lower housing. The shared surface also serves as a paper table used for guiding a bundle of paper into the electric stapler. A caulking plate for bending both legs of a staple that is made to penetrate through the bundle of paper by a hammer is provided on the shared surface. Since the electric stapler is arranged in an upper part and the electric pencil sharpener is arranged in a lower part, it is possible to provide an electric stapler with pencil sharpener in which cutting waste generated by sharpening a pencil does not affect the stapling operation and good stability is achieved because of a lowered weight balance and which requires only a small installation area on a desk.

A multi-purpose hand tool has a first member having opposite main surfaces and an elongated slot extending through the the main surfaces. A second member is slidably and pivotally coupled to one of the main surfaces of the first member. The second member has opposite main surfaces and a through-hole which extends through the main surfaces thereof and is generally vertically aligned with the elongated slot of the first member to define with the elongated slot a passage for receiving therethrough a marking member having a marking portion for contacting the surface of the material during a marking operation. A coupling assembly slidably and pivotally couples the second member to the first member to allow the second member to slide on and pivot relative to the first member between a first position in which the multi-purpose hand tool can be used to conduct a first marking operation on the surface of the material, and a second position in which the multi-purpose hand tool can be used to conduct a second marking operation on the surface of the material different from the first marking operation.

An automatic pencil sharpener has a plurality of different sizes of pencil selector openings in a front side of a pencil selector panel, and an annulus groove at the back side of the pencil selector panel for mounting the trigger.
