Abstract
Power drive tools are described. The tools include one or more threading pawls, one or more release pawls, and a drive ring selectively positionable relative to the tool and engaged with the pawls to selectively extend or retract the pawls. Also described are tools that include one or more lights to illuminate a workpiece. Also described are tools having distally located shoulder regions at which force may readily be applied. In addition, gear train assemblies for use in the power drive tools are described.
Claims23
A power drive tool comprising:
- a tool body;
- a tool head portion extending from the tool body, the tool head portion defining an axially accessible tool opening, the tool head portion including a cylindrical wall concentrically and rotatably supported in the tool opening;
- at least one threading pawl radially positionable to extend into the tool opening;
- at least one release pawl radially positionable to extend into the tool opening;
- a drive ring rotatably mounted on the tool head portion, the drive ring engaged with the at least one threading pawl and the at least one release pawl and rotatably positionable between (i) a first position in which the at least one threading pawl extends into the tool opening, and (ii) a second position in which the at least one threading pawl is retracted from extending into the tool opening and the at least one release pawl extends into the tool opening.
