Abstract: A power tool includes a motor and an output assembly configured to receive torque from the motor. The output assembly includes an anvil having a cylindrical body portion, an output member configured to engage a socket, and a curvilinear transition portion that tapers between the body portion and the output member. The transition portion defines a radius in a plane containing a rotational axis of the anvil that is greater than 1.5 mm. The output assembly also includes a pawl that is moveable between a first position in which the pawl is operatively coupled to drive the anvil in a first direction and a second position in which the pawl is operatively coupled to drive the anvil in a second direction opposite the first direction.

Abstract: A power tool includes a switch moveable between a first position enabling activation of a motor and a second position disabling the motor. The power tool includes a trigger movably coupled to a housing of the power tool between an OFF position and an ON position. The switch moves from the second position to the first position in response to the trigger moving from the OFF position to the ON position. The power tool includes a trigger lock-off pivotably coupled to the housing between a lock position and an unlock position. The trigger lock-off is engageable with the trigger to inhibit movement of the trigger from the OFF position to the ON position when the trigger lock-off is in the lock position. The trigger lock-off allows movement of the trigger from the OFF position to the ON position when the trigger lock-off is in the unlock position.

Abstract: A power tool includes an elongated shaft forming a handle and a tool head located at one end of the handle. The tool head includes a working element and a driven shaft configured to drive the working element. A powerhead located at an opposite end of the handle and includes an input shaft. A driveshaft extends between the tool head and the powerhead. The driveshaft is rotatably coupled to the input shaft and the driven shaft to transfer torque from the powerhead to the working element of the tool head. At least a portion of the driveshaft extending between the powerhead and the working element is constructed of a non-conductive material to inhibit transmission of electricity from the working element to the powerhead.

Abstract: A drain cleaner includes a handle assembly with a grip, a motor supported by the handle assembly, and a shroud coupled to and extending forwardly from the handle assembly. The shroud includes a closed end facing the handle assembly and an open end facing away from the handle assembly. The drain cleaner also includes a drum assembly rotatably coupled to the handle assembly and positioned within the shroud. The drum assembly is operable to be rotated by the motor relative to the handle assembly and the shroud. The drain cleaner further includes a flexible cable stored within the drum assembly. The drum assembly encloses the flexible cable.

Abstract: A reciprocating saw includes a blade assembly having a spindle and a blade clamp. The blade clamp includes a cover rotatably coupled to the spindle, and a detent movable in a radial direction to adjust the blade clamp between a locked configuration and an unlocked configuration. The cover is rotatable between a first rotational position relative to the spindle coinciding with the locked configuration, and a second rotational position relative to the spindle coinciding with the unlocked configuration. The reciprocating saw further includes a barrel surrounding at least a portion of the blade clamp. The barrel includes a plurality of projections extending from the barrel toward the blade clamp. At least one of the projections is engageable with the cover to rotate the cover from the second rotational position to the first rotational position, thereby adjusting the blade clamp from the unlocked configuration toward the locked configuration.

Abstract: An electric motor assembly includes a circuit board, a rotor assembly, and a stator assembly having a first end coupled to the circuit board and a second end opposite the first end. The stator assembly also includes an annular stator body having a plurality of inwardly projecting teeth. The stator assembly further includes windings wrapped about the stator body to form a plurality of coils. The stator assembly also includes a terminal coupled to an outer periphery of the stator body and extending longitudinally between the first end and the second end. The terminal is coupled to the circuit board at the first end and is coupled to the windings at the second end to electrically connect the windings to the circuit board. The terminal is molded to an attachment member, and the attachment member is molded to the outer periphery of the stator body.

Abstract: A ratchet tool has a handle housing and a ratchet assembly including a pawl and an output shaft. The pawl is moveable between a first position in which the pawl is operatively coupled to drive the output shaft in a first direction and a second position in which the pawl is operatively coupled to drive the output shaft in a second direction opposite the first direction. A switch in the handle housing has an external actuation surface for engagement with an operator's hand. The ratchet tool also has a rotatable gear having at least one tooth, the rotatable gear operatively coupled to the pawl such that rotation of the rotatable gear effectuates movement of the pawl between the first and second positions. A linkage is operatively coupled to the rotatable gear to effectuate rotation of the rotatable gear by actuation of the switch.
