A laser leveling apparatus includes a housing, a first laser generator, and a second laser generator such that the laser leveling apparatus is reorientable between an upright position, in which the first laser generator is oriented for generating a horizontal line when activated and in which the second laser generator is oriented for generating a first vertical line when activated, and a side lying position, in which the first laser generator is oriented for producing a second vertical line when activated and in which the second laser generator is oriented for producing the first vertical line when activated. The laser leveling apparatus further includes an active leveling platform assembly having a plurality of sensor assemblies in electronic communication with a plurality of motor assemblies for tilting an upper frame assembly supporting the first laser generator and the second laser generator about a lower frame assembly about three perpendicular axes.

A laser level system including a laser level and a bracket. The laser level projects at least one laser line and is mounted on the bracket. An integral power source is disposed within an interior of the bracket. The power source powers the laser level and the laser level is rotatable relative to the bracket.

A lifting and lowering tool includes a foot configured to be supported on a surface, a bar extending therefrom, and a movable assembly including a housing, a movable platform shaped to support a load that extends from the housing, a lifting actuator configured to incrementally move the movable assembly along the bar away from the foot, a lowering actuator configured to incrementally move the movable assembly along the bar towards the foot, and a release actuator configured to disengage the movable assembly from the bar to allow free movement of the movable assembly along the bar. In embodiments, the movable assembly engages the bar through locking plates that extend through a flange of the movable assembly. In embodiments the release actuator is spaced from the lifting actuator and the lowering actuator to prevent inadvertent actuation of the release actuator. In embodiments a flange of the movable assembly surrounds the bar.

A blade retention mechanism is provided including a blade clamp having a lever portion and a protrusion portion coupled to a first end of the lever portion. The lever portion rotates at the first end of the lever portion between a first open position and a second closed position. The protrusion portion of the blade clamp defines an over-center cam that presses a blade into a blade holder of a knife when the lever portion is rotated into the second closed position.

A laser level system includes a laser level configured to project a laser beam and a laser detector configured to detect the laser beam projected by the laser level. The laser detector includes at least one array of photo detector configured to detect the laser beam. The laser level and laser detector are configured to wirelessly communicate. The laser level and the laser detector are configured to selectively operate in a beam find mode. The laser level is configured to perform sweeps in the beam find mode to locate the laser beam on the at least one array of photo detectors.

A power tool includes a head interface coupled to a forward end of an output shaft and a tool head element for engagement on the head interface. The tool head element has a housing including an input shaft configured to removably couple with the output shaft and a collar comprising locking elements. In embodiments, locking elements are biased inwardly towards the input shaft by biasing elements (springs). In others, magnet(s) and/or ball locking elements may be utilized. Upon attachment of the tool head element to the head interface, the tool head element may held by the provided elements (e.g., locking elements, biasing springs, magnets, balls) onto the head interface and a drive connection between the output shaft and input shaft is established. Thus, when a motor and transmission assembly of the tool is operated, the input shaft rotates with the output shaft about the axis and thus drives the tool head element.
