Abstract: A spool and a trimmer head. The trimmer head includes a housing defining a cavity and rotatable about an axis. A spool is supported in the cavity and operable to support line to be dispensed. The spool is movable along the axis relative to the housing, and the spool and the housing define cooperating conical surfaces to center the spool during movement of the spool toward and in a position relative to the housing.

Abstract: A hand-held knockout punch driver includes a housing, a motor, a drive assembly with an output member movable relative to the housing, and a head unit removably coupled to the housing. The head unit includes a body, an input member movable relative to the body, and a draw rod to which a punch or a die is attachable. The draw rod is configured to move axially relative to the body in response to movement of the input member relative to the body. The knockout punch driver also includes a quick-release mechanism to removably couple the body to the housing. The output member is configured to engage the input member such that the input member moves relative to the body in response to movement of the output member relative to the housing, and the body engages the quick release mechanism separately from engagement between the output member and the input member.

Abstract: A transducer assembly for use in a power tool includes a bracket affixed to a housing of the power tool and a protrusion having an arcuate outer periphery. The protrusion is offset from a central axis of the bracket and extends from the bracket in a direction parallel with the central axis. The transducer assembly also includes a transducer having an inner hub with an aperture through which a distal end of the protrusion is received. The arcuate outer periphery of the protrusion is in substantially line contact with a wall segment at least partially defining the aperture. The transducer also includes an outer rim affixed to a ring gear of the power tool, a flexible web interconnecting the inner hub to the rim, and a sensor affixed to the flexible web for detecting strain of the flexible web in response to a reaction torque applied to the ring gear.

Abstract: A fastener driver includes a housing having a handle portion. A motor is positioned within the housing. The fastener driver further includes an air compressor including a compressor cylinder and a compressor piston movable within the compressor cylinder in a reciprocating manner to compress air within the compressor cylinder. The fastener driver further includes a drive train converting torque from the motor to a linear force applied to the compressor piston, causing the compressor piston to move in the reciprocating manner. At least a portion of the drive train extends through the handle portion of the housing.

Abstract: A battery pack that is connectable to and supportable by a power tool (e.g., a hand-held power tool). The battery pack includes a top housing having a support member. The support member of the battery pack top housing is configured or operable to reinforce a support portion of the battery pack that is used to connect the battery pack to the power tool. By reinforcing the support portion of the battery pack, an interface between the battery pack and the power tool is able to withstand greater forces (e.g., from vibrations caused by the power tool).

Abstract: A power tool includes a motor having an output shaft, an extensible member driven by the motor, a working assembly movable in response to contact with a distal end of the extensible member, a first sensor configured to detect a home position of the extensible member, a second sensor configured to detect rotation of the motor output shaft, and a controller in electrical communication with the first and second sensors. The controller is configured to drive the motor output shaft in a first rotational direction a predetermined number of revolutions counted by the second sensor, thereby displacing the extensible member from the home position. The controller is also configured to drive the motor output shaft in an opposite, second rotational direction to thereby return the extensible member until the home position is detected by the first sensor.

Abstract: A hand-held knockout driver includes a main housing having a handle portion, a motor positioned within the main housing, a hydraulic assembly driven by the motor and including a reservoir containing hydraulic fluid, a secondary housing coupled to the main housing and defining a bore therein, a working piston moveable within the bore between a rest position and an actuated position, and a work zone defined between the secondary housing and the working piston into which pressurized hydraulic fluid discharged from the hydraulic assembly is received. One unit of fluid is added to the work zone to move the working piston from the rest position to the actuated position. The reservoir has a fill capacity no greater than about 1.5 units of fluid.

Abstract: A power tool having a housing, a motor, a tool holder driven about an output axis by the motor, and an output element for performing an operation on a workpiece. The tool holder has a locating feature including a tapered portion becoming narrower in a direction away from the surface of the tool holder. The output element has an aperture for receiving the locating feature and a face facing the surface of the tool holder when the locating feature is received. The power tool also includes a flange for transferring a clamping force for urging the output element towards the tool holder and a tab projecting from the flange for finger tightening the flange. A biasing member provides the clamping force toollessly. A gap is defined between the surface of the tool holder and the face when the tapered portion of the locating feature is fully received in the aperture.
