Abstract: A hand-held machine tool having a, in particular rod-shaped, handle element for an operator to grasp and having a machining head, which is movably mounted on the handle element by means of a joint assembly and which has an electric drive motor for driving a tool holder for holding a machining tool, wherein a bottom side of the handle element and a machining side of the machining head face a workpiece in a base position of the machining head, wherein the joint assembly is connected to the machining head in an articulated-connection region of the machining head, wherein a flexible suction hose for conducting a suction flow from the machining head to the handle element extends between the handle element and the machining head, which suction hose is fastened to an end region of the handle element by means of a first hose end and to a suction connection of the machining head by means of a second hose end.

Abstract: A plug connector for connecting an attachment cable to a mating plug connector of an electrical appliance in the form of a vacuum cleaner, wherein the plug connector has a contact carrier having plug contacts which are connected or connectable to the attachment cable and which can be brought into an electrical contact position with mating plug contacts of the mating plug connector by a plugging movement along a plug axis, wherein the contact carrier is received, in an axially movable manner with respect to the plug axis, in a plug housing which is mounted rotatably about the plug axis with respect to the contact carrier, wherein rotary form-fit contours are arranged on the plug housing and can be brought into form-fit engagement with mating rotary form-fit contours of the mating plug connector by a rotation movement of the plug housing about the plug axis with respect to the contact carrier, such that the plug connector is secured on the mating plug connector in a tension-resistant manner with respect to the

Abstract: The invention relates to a guiding device 100, a system comprising a guiding device and a tool 111 for surface treatment, a method for surface treatment with the guiding device 100 and a method for retrofitting a tool 111 with the guiding device 100. The guiding device 100 comprises at least one guide element 101, one angle device 102 and one connection arrangement 130 for connecting the guiding device to the tool 111. Furthermore, a predetermined angle between the plane 180 of the at least one guide element 101 and a plane of action 110 of the connectable tool 111 is set by means of the angle device 102. The guiding device 100 is furthermore characterised in that it is switchable between at least one flexible operating state and one rigid operating state.
