    • A hand-held device for shredding paper comprising a pair of rotary cutting wheels disposed within a housing between an inlet slot and an outlet slot. A motor is positioned in the handle to drive the cutting wheels through a gear assembly. One wheel serves as a drive wheel, which is coupled directly to the gear assembly, and the other wheel serves as an idler, driven from a spur gear attached to the drive wheel at the end opposite a gear case. Paper sheets are fed into the inlet slot and pulled between the wheels. Wheels are comprised of a stack of alternating discs of a large and small radius, and staggered so as to allow the two wheels to be interleaved while rotating in opposite (clockwise and counterclockwise) directions and maintain clearance. Large discs have a frictional edge to grab and feed the paper into the intersection of the wheels, tearing the paper into strips and forcing the strips into the outlet slot. A battery compartment in the handle contains the batteries for energizing the motor.
    • 一种用于粉碎纸的手持装置,包括一对旋转切割轮,其设置在壳体内的入口槽和出口槽之间。 马达定位在手柄中以通过齿轮组件驱动切割轮。 一个轮作为驱动轮,该驱动轮直接连接到齿轮组件,而另一个轮作为一个惰轮,从与齿轮箱相对的一端附接到驱动轮的正齿轮驱动。 纸张进入入口槽并在轮子之间拉动。 车轮由大小半径的交替盘组成,交错排列,以便在相反(顺时针和逆时针)方向旋转时允许两个车轮交错并保持间隙。 大盘具有摩擦边缘,用于抓住并将纸进给到车轮的交叉处,将纸撕成条并迫使条进入出口槽。 手柄中的电池仓包含用于为电机通电的电池。
