Abstract: A string trimmer assembly includes a trimmer head rotatably driven by a drive shaft and defining a cavity, a spool supported in the cavity of the trimmer head and operable to support line to be dispensed, and a flange formed on the spool. The spool includes a through hole for receiving the line, which is dispensable though an opening in the trimmer head. The flange is formed on the spool in a common plane with the opening and with the through hole. The flange separates the line into a first line portion and a second line portion. The first line portion is positioned on a first side of the flange, and the second line portion is positioned on a second side of the flange.

Abstract: A socket for use with an anvil of a rotary power tool includes a socket body with a driven end and a working end. The socket also includes a locking element adapted to engage a locking recess in the anvil. The locking element is positioned within a slot in the socket body and movable between a lock position and a release position. A locking sleeve surrounding the driven end of the socket body is also included. The locking sleeve is movable between a lock position and a release position. An engagement ring is included on the locking sleeve and is adapted to engage the locking element preventing radially outward motion of the locking element when in the lock position. The socket also includes a first spring adapted to bias the locking element toward the lock position, and a second spring adapted to bias the locking sleeve toward the lock position.

Abstract: A blade clamp is configured for use with a power tool having a reciprocating spindle. The blade clamp includes a cover assembly rotatably coupled to the spindle, and a detent received within a first bore of the spindle. The detent is movable in a radial direction relative to a longitudinal axis of the spindle by engagement with the cover assembly to adjust the blade clamp between a locked configuration and an unlocked configuration. The blade clamp further includes a sleeve in which the detent is slidably received. The sleeve is at least partially positioned within the first bore. A plunger is positioned within a second bore of the spindle. The second bore extends along a longitudinal axis that is parallel with the longitudinal axis of the spindle. The second bore is contiguous with a blade slot of the spindle.

Abstract: A stud punch includes a housing, a motor positioned within the housing, and a planetary gear train that receives torque from the motor. The stud punch also includes a punch movable between a retracted position and an extended position, and a scotch-yoke mechanism coupled between the planetary gear train and the punch. The scotch-yoke mechanism is configured to convert torque received from the planetary gear train to a reciprocating linear force, causing the punch to move between the retracted position and the extended position.

Abstract: A fan includes a hub and a plurality of blades extending radially outwardly from the hub and spaced circumferentially about the hub. The plurality of blades includes a reference blade, a first blade, and a second blade. The reference blade is disposed after the first blade in a circumferential direction about the hub. The second blade is disposed after the reference blade in the circumferential direction. The first blade is circumferentially spaced a first distance from the reference blade. The second blade is circumferentially spaced a second distance from the reference blade. The first distance is greater than the second distance.

Abstract: A blade clamp, for use with a power tool having a reciprocating spindle, includes a cover rotatably coupled to the spindle and a detent received within a bore of the spindle. The detent is movable in a radial direction relative to a longitudinal axis of the spindle 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 blade clamp further includes a sleeve in which the detent is slidably received. The sleeve includes a non-corrosive material for inhibiting corrosion of the detent.
