Abstract
A portable electric rescue tool, such as spreader and cutter tool, that allows for manual or remote operation, and operates on a DC power source, which may be an external power source and/or an onboard rechargeable battery. For example, the tool includes a battery cradle or battery attachment portion adapted to removably receive a rechargeable battery pack and electrically couple the battery pack to the tool. The tool also includes a power adapter that is adapted to be removably coupled to the battery attachment portion instead of the battery pack, and allows the tool to be electrically connected to an external DC power source, such as a vehicle battery or other DC power source.

A tool with first and second jaws, the tool comprising:
- a housing including a battery attachment portion and electrical contacts exposed in the battery attachment portion, wherein the battery attachment portion includes a groove formed in a first side of the battery attachment portion, and a latch with a protrusion that projects inwardly into the battery attachment portion from a second side of the battery attachment portion opposite the first side;
- first and second handles coupled to the housing, wherein the battery attachment portion is positioned substantially between the first and second handles;
- a battery pack adapted to removably couple to the battery attachment portion and electrically couple to the electrical contacts, wherein the battery pack includes first and second projections respectively extending from opposing ends of the battery pack, and when the battery pack is coupled to the battery attachment portion, the first projection is disposed in the groove, and the second projection is engaged with the protrusion;
- a motor disposed in the housing, the motor is adapted to receive power from the battery pack, and provide output torque;
- a gear assembly disposed in the housing and operably coupled to the motor, the gear assembly is adapted to receive the output torque from the motor;
- and
- an actuator assembly operably coupled to the gear assembly and adapted to receive output torque from the gear assembly, and provide torque to operate the jaws.
