Abstract: An electric pencil sharpener includes a motor, a transmission subassembly and a cutter subassembly driven by the motor, a feeding subassembly and at least one resilient adjusting means. The feeding subassembly includes a feeding gear set coupled to the transmission subassembly and two feeding rollers adapted to sandwich a pencil to be sharpened, at least one feeding roller is driven by the feeding gear set. The pair of brackets is arranged in parallel, respectively defining slide ways to movablely support the feeding rollers. A feeding space is defined between the two brackets. The at least one resilient adjusting means connects the two feeding rollers outside or inside the feeding space, adapted for keeping the feeding rollers nipping the pencil and engendering a pencil feeding friction.

Abstract: The present invention relates to a finger musical instrument, including a first glove and a second glove, some performance keys distributed on a fingertip of each of the gloves, and a sound box positioned at each of the gloves. The finger musical instrument further includes a combination key positioned at palm heel of each of the gloves. Each of the sound boxes is connected with a controller. The performance key and the combination key on the same glove are all connected with the corresponding controller. Therein the performance key and the combination of the performance key and the combination key of one glove gives out one octave sound, while the performance key and the combination of the performance key and the combination key of the other glove gives out another octave sound. Each of the controllers is provided with a range regulation switch used for making a sound higher or lower by an octave on each of the gloves.

Abstract: An electric pencil sharpener, comprises a base, a powering device, a feeding subassembly, a cutter subassembly and an adjusting subassembly. Two brackets (31, 32) are mounted on the base, standing face to face. Each of the brackets defines two guideways (35) therein. The powering device is attached to the base. The feeding subassembly comprises a feeding gear module and a pair of feeding rollers (23, 24). The feeding rollers are respectively supported in guideways between the brackets. The feeding gear module driven by the powering device makes one of feeding rollers to rotate therein. The adjusting subassembly encompasses the feeding rollers on the bracket. The adjusting subassembly pushes the feeding rollers to move along the guideways. With restriction of the guideways, the distance between the two feeding rollers alters so that pencils with different size can be automatically fed and processed.

Abstract: An electric stapler comprises an enclosure, a motor, a power transmission device, a working arm pivotally attached to the enclosure, a magazine receiving a plurality of staples and a clinching assembly. A guide device is mounted upon the working arm and rotating therewith. The guide device defines a guideway therein. The magazine is slidably engaged with the working arm. The clinching assembly combines a blade support and a blade, both received in the guideway of the guide device and movable therein. The blade support is engaged with the lever. The power transmission device transmits power and torque from the motor to the clinching assembly. The guide device is mounted upon the working arm and rotates therewith, the blade support slides in the guideway and simultaneously rotates with the guide device, thereby no interferences between the blade support and guide device occurs.

Abstract: An automatic pencil sharpener having a motor, a transmission device, a cutter assembly, a feeding device, a feeding reverse mechanism, and a manual reverse mechanism. The feeding device has a pair of feeding rollers for feeding the pencil. The manual reverse mechanism for manually retreating the pencil has a pushing rod and a key switch. The pencil is fed by the feeding device and delivered to the cutter assembly. The cutter assembly processes the pencil. After the pencil is shaved, the feeding reverse mechanism drives the motor to rotate in a reverse direction so as to retreat the pencil from the sharpener. When the pencil is too short to shave and stops in the sharpener, the pencil is retreated from the sharpener by the manual reverse mechanism.
