Abstract: An extraction connection system for portable machine tools includes at least one tool connection element, at least one suction apparatus connection element, and at last one fixing unit. The at least one tool connection element is configured to be connected to the at least one suction apparatus connection element. The at least one fixing unit includes at least one movably mounted fixing element configured to fix the at least one tool connection element and the at least one suction apparatus connection element against a movement relative to each other in at least one direction.

Abstract: The disclosure relates to an extraction connection system for portable machine tools, and comprises at least one tool connection element, at least one suction apparatus connection element, and at least one fixing unit. The at least one tool connection element is configured to be connected to the at least one suction apparatus connection element. The at least one fixing unit includes at least one movably mounted fixing element configured to fix the at least one tool connection element and the at least one suction apparatus connection element against a movement relative to each other in at least one direction.

Abstract: A machine tool clamping device for clamping a laminar machining tool to a tool holder that is eccentrically movably mounted includes at least one clamping unit with at least one movably mounted clamping element. The machine tool clamping device also includes at least one slotted link movement unit configured to move the clamping element in at least one operating state so as to generate tensile stress in the laminar machining tool.

Abstract: A machine tool comprises a dust collection receptacle that is releasably connected to the machine tool. A blow-off neck is arranged on a housing part, and a receptacle neck is arranged on the dust collection receptacle. The two necks can be axially plugged into each other. In the plugged state, supporting surfaces on the dust collection receptacle and on the housing part rest against each other in a planar manner, said supporting surfaces extending at an angle from the longitudinal axis of the plugged necks. The face of one neck forms a first supporting surface.
