Abstract: A power tool includes an output shaft, a planet carrier, and a buffer mechanism. The planet carrier is configured to be rotatably connected with the output shaft to drive the output shaft during operation, and there is a gap between an inner side surface of the planet carrier and a circumferential surface of the output shaft. A buffer mechanism is provided on at least one of the inner side surface of the planet carrier and the circumferential surface of the output shaft near the gap. The buffer mechanism is configured not to actively apply pressure to the output shaft and the planet carrier, and to buffer the impact force between the output shaft and the planet carrier, when the output shaft slides relative to the planet carrier under the action of inertial force.

Abstract: A power tool includes a housing, a battery coupled to the housing, and a battery cover which covers at least a portion of the battery. The battery cover includes an expandable portion. The expandable portion is moveable from a collapsed position to an expanded position. When the expandable portion is in the collapsed position, the battery cover has a first internal area. When the expandable portion is in the expanded position the battery cover has a second internal area. The first internal area is less than the second internal area.

Abstract: A floor cleaner having a recovery tank, a suction source, and a filter basket. The suction source is configured to generate an airflow along a fluid flow path to draw fluid and debris from a surface to be cleaned into the recovery tank. The recovery tank has an outlet duct on a tank body. The filter basket is positioned in the outlet duct on the tank body and configured to filter debris from the airflow.

Abstract: A surface cleaning tool including a housing forming a handle, a motor, a fluid reservoir coupled to the motor for rotational movement, a cleaning head coupled to and rotatable with the fluid reservoir, and a valve configured to control the flow of fluid from the fluid reservoir to the cleaning head. The valve is actuated by movement of the fluid reservoir from a first position to a second position relative to the cleaning head.

Abstract: A floor cleaner that includes a cleaning head, an agitator drive, and an agitator. The cleaning head includes an agitator chamber having an opening facing toward a surface to be cleaned. The agitator is rotatably disposed within the agitator chamber and positioned to contact the surface to be cleaned through the opening. The agitator extends longitudinally between a first end and a second end along an axis of rotation. The agitator includes a core operably connected to the agitator drive, rotatable about the axis and at least one molded agitating member integrally formed with the core. The agitating member extends from the core to contact the surface to be cleaned.

Abstract: A docking station for use with an autonomous tool comprising a docking module for detachably receiving the autonomous tool and a guiding module arranged to guide the movement of the autonomous tool towards the docking module, wherein the autonomous tool, upon termination of the movement, is received by the docking module at a predetermined position and orientation. The present invention also discloses an autonomous lawn mower having a docking module and a guiding module and a method of guiding an autonomous tool towards a docking station.
A docking station for use with an autonomous tool (100) comprises a docking module (200) for detachably receiving the autonomous tool (100) and a guiding module (210) arranged to guide the movement of the autonomous tool (100) towards the docking module (200), wherein the autonomous tool (100), upon termination of the movement, is received by the docking module (200) at a predetermined position and orientation (400). An autonomous lawn mower has a docking module (200) and a guiding module (210). A method is applied to guide an autonomous tool (100) towards a docking station.

Abstract: A fastener driver includes a drive blade movable from a retracted position to a driven position for driving a fastener into a work piece. The fastener driver further includes a gas spring mechanism for driving the drive blade from the retracted position to the driven position. The gas spring mechanism is moveable between a retracted state and a driven state. The fastener driver further includes a first return mechanism for moving the drive blade from the driven position toward the retracted position, and a second return mechanism for returning the gas spring mechanism toward the retracted state separately from movement of the drive blade.
