Abstract
A portable rescue tool which operates off electric power and which comprises a clutch mechanism for orienting high torque spreading and/or cutting motion that is produced by the portable rescue tool in a plurality of possible directions with respect to the portable rescue tool. The portable rescue tool comprises a rotary switch for controlling the operation of the portable rescue tool, a DC motor connected to the rotary switch for providing a high speed, low torque output, a gear reduction assembly coupled to the DC motor for decreasing the speed and increasing the torque of the DC motor output, an actuator assembly coupled to the gear reduction assembly for providing a low speed, high torque output, and a clutch mechanism associated with the actuator assembly for orienting the direction of the low speed, high torque output with respect to the portable rescue tool.
