The invention provides a transmission assembly and a power tool. One form of the power tool includes a rotatable driven member for releasably gripping and rotating a working element and a transmission assembly for transmitting rotation from a motor to the driven member. The transmission assembly includes a rotatable input shaft and first and second rotatable output shafts. In a first speed setting the input shaft is selectively lockable together with the first output shaft so that the locked input shaft and first output shaft rotate in unison to drive rotation of the driven member at a first speed of rotation relative to a speed of rotation of the motor. In a second speed setting the input shaft is selectively lockable to the second output shaft so that the locked input shaft and second output shaft rotate in unison to drive rotation of the driven member at a second speed of rotation relative to the speed of rotation of the motor. Another form includes a torque controller operable for controlling torque supplied from the motor to the driven member to render the driven member stationary when the amount of torque supplied from the motor to the driven member exceeds a pre-determined level. Another form includes a switch mechanism for adjusting the transmission assembly between the first and second speed settings and for rendering the torque controller operable or inoperable. Another form includes a torque controller for use with a power tool and operable for controlling torque transmitted from an input shaft to an output shaft.

A portable power drill () is disclosed having a chuck or drill collar () at one end and a substantially cylindrical (or frusto-conical) twist throttle handle () at the other end. Rotation of the handle in the direction of forward rotation of the chuck decreases the drill speed and, conversely, rotation of the handle in the direction of reverse rotation of the chuck increases the drill speed. Consequently, in the event of an auger locked in the chuck becoming jammed, the reaction forces experienced by the drill unit rotate the drill unit in a direction such that throttle decreases the drill speed. In addition, the drill unit is provided with forward () and reverse gears () and a forward/reverse selection mechanism () which is actuated by a forward force, or a withdrawing force respectively being applied to the drill unit via an operator who holds the handles () of the drill unit. 1. A portable power drill unit comprising an operational axis having a chuck means at one end and a substantially cylindrical or frusto-conical twist throttle handle at the other end , and wherein rotation of the handle in the direction of forward rotation of the chuck means decreases the drill speed , and rotation of the handle in the direction of reverse rotation of the chuck means increases the drill speed , whereby reaction forces created by a jammed auger rotated by said chuck means decrease the drill speed.2.

Described herein is a novel lanyard system for removable pieces connected to and detached from a piece receiver of a power tool. The system includes one or more lanyard assemblies, each with a two ended strap and a retraction system fixed to the tool all in a storage region outside of the tool. In particular, one end of the strap is connected to the piece and the other strap end is connected to one end of the retraction system. The other end of the retraction system is connected to the outside of the tool. The strap is of sufficient length for the retraction system to retract a piece to the storage region outside the tool after disconnection from the piece receiver.
