Abstract: A cutting tool includes a housing, a motor positioned within the housing, a pipe holder formed in the housing, a blade pivotally coupled respective to the pipe holder at a pivot point for movement relative to the pipe holder during a cutting motion, a drive mechanism including a first gear, and a quick-change mechanism rotationally coupling the blade to the first gear. The quick-change mechanism is operable to selectively de-couple the blade from the first gear to remove the blade for replacement.

Abstract: A blade change mechanism configured to attach a blade to a transmission rod of a power tool, the blade change mechanism including a support body, a blade retention structure, and a component. The blade retention structure is coupled to the support body and includes a blade retention component movable to hold the blade in a locked state in response to engagement of the blade with the blade change mechanism on insertion of the blade. The component is movable to vary the blade retention component to hold the blade in the locked state. The component is further movable to vary the blade retention component to an unlocked state in which the blade retention structure is disengaged from the blade. The blade retention structure is held in the unlocked state absent the blade being fully inserted into the blade change mechanism.

Abstract: A cleaning implement including a foot, a motor, and an eccentric mass. The foot has a foot plate and an oscillation plate movably coupled to the foot plate. The motor is coupled to at least one of the foot plate and the oscillation plate. The motor rotates about a motor axis extending at a non-perpendicular transverse angle relative to the surface. The eccentric mass is coupled to the motor to generate an oscillating force between the foot plate and the oscillation plate upon operation of the motor. The oscillating force has a planar component parallel to the oscillation plate and a perpendicular component perpendicular to the oscillation plate.
