Abstract: An interchangeable-tool machine interface for a cleaning brush, includes a drive interface and output interface that are separable and connectable without tools and are separable or connectable in several discrete angular positions by axial displacement along a common axis of rotation. The output interface has centering walls and resiliently displaceable latching-means walls, the centering walls and the resiliently displaceable latching means walls are arranged so as to be angularly offset from one another in the circumferential direction about the axis of rotation. The drive interface has centering and mating latching-means walls that are arranged so as to be angularly offset from one another in the circumferential direction about the axis of rotation and, per wall, are designed to correspond both to the centering walls and to the latching means walls of the output interface.

Abstract: A hand-held power tool, in particular a grinder, for simultaneously driving multiple grinding discs, includes at least one output shaft housing which surrounds multiple output shafts orthogonally to their output shaft axes, and a motor housing which at least substantially surrounds a motor orthogonally to the motor shaft axis. A cross-sectional surface of the motor housing running orthogonally to the motor shaft axis, in a narrower region of the motor housing, is less than 70% of the area of a cross-sectional surface of the output shaft housing running orthogonally to the output shaft axes, in a wider region of the output shaft housing, and/or one, in particular two, of the output shaft axes, are located outside the motor housing, preferably outside a concavely indented region of the hand grip, of the motor housing, and/or of the transition region between the hand grip and the motor housing.

Abstract: A hand-held power tool, in particular a grinder, for simultaneously driving a plurality of grinding plates includes a main housing, which accommodates at least one motor for driving the grinding plates. A handle housing forms a handle and protrudes substantially perpendicularly to the main housing, and in particular the handle housing accommodates a storage battery. The hand-held power tool includes a motor having a drive shaft, which defines a motor axis, a central wheel, which is driven by the motor and defines a central wheel axis, and a plurality of, in particular three, output shafts, which are driven by the central wheel and define respective output shaft axes. Each output shaft is provided for driving one grinding plate or at least one grinding plate receptacle, and the motor axis is arranged eccentrically to the central wheel axis between a front output shaft axis and the central wheel axis.

Abstract: A tool coupling device for a receptacle of a machine tool separating device formed as a closed system includes at least one cutting strand tensioning unit that has at least one tensioning element. The tool coupling device also includes at least one operating unit that includes at least one operating element. The cutting strand tensioning unit includes at least one gear unit that is configured to move the tensioning element as a result of an actuation of the operating element of the operating unit.

Abstract: A closure device, in particular a tool-holder closure device, includes at least one movably mounted closure element and at least one securing unit. The securing unit includes at least one movably mounted securing element configured to secure the closure element in at least one position thereof. The closure device further includes at least one stop unit which has at least one stop element. The stop element, depending on at least one position of the closure element, is configured to stop the securing element at least largely against a movement relative to the closure element.

Abstract: A tool coupling device is configured to hold a machine tool cutting device. In particular, the tool coupling device is configured to hold a machine tool cutting device configured as a closed system, having at least one cutting train clamping unit for generating a cutting train clamping force and having at least one tool-holding unit comprising at least one movably mounted tool-holder element. The tool coupling device includes at least one movement-coupling unit by which the tool-holder element can be coupled with a clamping element for a movement of the clamping element of the cutting train clamping unit.

Abstract: A clamping device for a hand-held power tool includes at least one clamping unit configured to clamp a processing tool in an axial direction and at least one operating unit configured to actuate the at least one clamping unit. The at least one operating unit has at least one jaw coupling element configured to couple the at least one operating unit to the at least one clamping unit in a rotationally fixed manner. The at least one jaw coupling element is supported so as to be movable at least substantially parallel to the axial direction.
