Erfindungsgemäß weist die Handwerkzeugmaschine einen Spannhals auf, welcher sich in einer Umfangsrichtung zumindest teilweise um die Ausgangswelle erstreckt. Unter einem "Spannhals" soll in diesem Zusammenhang insbesondere ein Bauteil verstanden werden, welches dazu vorgesehen ist, eine Zubehörbefestigungsvorrichtung vorzugsweise form- und/oder kraftschlüssig aufzunehmen und zu tragen und welches sich vorzugsweise in einem Winkel ungleich 0° und vorzugsweise in einem Winkel größer 45° und besonders bevorzugt zumindest im Wesentlichen senkrecht zu einer Haupterstreckungsrichtung der Handwerkzeugmaschine erstreckt und/oder sich zumindest im Wesentlichen parallel zur Ausgangswelle der Getriebeeinheit erstreckt. Dabei soll unter "im Wesentlichen" insbesondere verstanden werden, dass eine Abweichung eines tatsächlichen Winkels von einem vorgegebenen Winkel insbesondere weniger als 25%, vorzugsweise weniger als 15% und besonders bevorzugt weniger als 5% des vorgegebenen Winkels beträgt. Unter "vorgesehen" soll insbesondere speziell ausgelegt und/oder ausgestattet verstanden werden. Durch den erfindungsgemäßen Spannhals kann eine vorteilhaft einfache Aufnahme eines Zubehörteils für die Handwerkzeugmaschine erreicht werden, wodurch insbesondere ein Bedienkomfort für einen Benutzer der Handwerkzeugmaschine vorteilhaft erhöht werden kann. Ferner kann mittels des erfindungsgemäßen Spannhalses auf vorteilhaft einfache Weise erreicht werden, dass eine Zubehörbefestigungsvorrichtung vorzugsweise in zumindest zwei verschiedenen Positionen relativ zur Umfangsrichtung des Spannhalses an dem Spannhals befestigt werden kann, wodurch eine Flexibilität der Handwerkzeugmaschine vorteilhaft erhöht werden kann.The invention is based on a hand-held power tool with a housing and with a drive unit, with a gear unit which is intended to convert a rotational movement of the drive unit into an oscillating movement, and which has an output shaft, and with a tool holder for fastening at least one insert tool , which can be driven in an oscillating manner via the output shaft of the transmission unit. According to the invention, the hand-held power tool has a clamping neck which extends at least partially around the output shaft in a circumferential direction. In this context, a "clamping neck" is to be understood in particular as a component which is intended to accommodate and carry an accessory attachment device, preferably with a form fit and/or force fit, and which preferably rotates at an angle other than 0° and preferably at an angle greater than 45° ° and particularly preferably at least substantially perpendicular to a main extension direction of the handheld power tool and/or extends at least substantially parallel to the output shaft of the transmission unit. “Substantially” is to be understood in particular as meaning that a deviation of an actual angle from a specified angle is in particular less than 25%, preferably less than 15% and particularly preferably less than 5% of the specified angle. “Provided” is to be understood in particular as being specially designed and/or equipped. The clamping collar according to the invention makes it possible to accommodate an accessory for the hand-held power tool in an advantageously simple manner, as a result of which, in particular, ease of use for a user of the hand-held power tool can advantageously be increased. Furthermore, by means of the clamping neck according to the invention, it can be achieved in an advantageously simple manner that an accessory fastening device can preferably be fastened to the clamping neck in at least two different positions relative to the circumferential direction of the clamping neck, as a result of which the flexibility of the hand-held power tool can advantageously be increased.
In einer besonders bevorzugten Ausgestaltung der Erfindung ist der Spannhals vorzugsweise einstückig mit einem, insbesondere aus einem Kunststoff gebildeten Gehäuse der Handwerkzeugmaschine ausgebildet sein. Unter "einstückig" soll insbesondere angeformt verstanden werden, wie vorzugsweise durch die Herstellung aus einem Guss und/oder durch die Herstellung in einem Ein- oder Mehrkomponentenspritzverfahren. Dadurch kann eine besonders vorteilhaft einfache und kostengünstige Herstellung der erfindungsgemäßen Handwerkzeugmaschine mit dem Spannhals erreicht werden. Es ist jedoch auch denkbar, den Spannhals andersartig stoffschlüssig an dem Gehäuse der Handwerkzeugmaschine zu befestigen, wie insbesondere durch Kleben und/oder Schweißen. Es ist ebenso denkbar, den Spannhals auf eine andere, einem Fachmann als sinnvoll erscheinende Weise, wie insbesondere kraftschlüssig durch Einpressen des Spannhalses in das Gehäuse der Handwerkzeugmaschine und/oder formschlüssig durch eine Verschraubung, an dem insbesondere aus einem Kunststoff gebildeten Gehäuse der Handwerkzeugmaschine zu befestigen.In a particularly preferred embodiment of the invention, the clamping neck is preferably designed in one piece with a housing of the hand-held power tool, which is in particular made of plastic. “In one piece” is to be understood in particular as being molded on, such as preferably by being produced from a single cast and/or by being produced in a one-component or multi-component injection molding process. As a result, a particularly advantageously simple and cost-effective production of the hand-held power tool according to the invention with the clamping neck can be achieved. However, it is also conceivable to fasten the clamping collar to the housing of the hand-held power tool in a different material connection, such as in particular by gluing and/or welding. It is also conceivable to fasten the clamping neck in a different manner that appears sensible to a person skilled in the art, such as in particular in a non-positive manner by pressing the clamping collar into the housing of the hand-held power tool and/or in a form-fitting manner by means of a screw connection to the housing of the hand-held power tool, which is in particular made of plastic.
Es ist auch denkbar, den Spannhals aus einem metallischen Werkstoff herzustellen. Dadurch kann der Spannhals vorteilhaft stabil und robust ausgestaltet werden. Der aus einem metallischen Werkstoff gebildete Spannhals kann vorzugsweise von dem, insbesondere aus einem Kunststoff gebildeten Gehäuse der Handwerkzeugmaschine umspritzt sein. Es ist auch denkbar, den Spannhals andersartig stoffschlüssig an dem Gehäuse der Handwerkzeugmaschine zu befestigen, wie beispielsweise durch Kleben, Schweißen usw. Es sind jedoch auch andere, einem Fachmann als sinnvoll erscheinende Ausgestaltungen des Spannhalses und dessen Befestigung am Gehäuse der Handwerkzeugmaschine denkbar.It is also conceivable to produce the clamping neck from a metallic material. As a result, the clamping neck can advantageously be made stable and robust. The clamping neck, which is formed from a metallic material, can preferably be encapsulated by the housing of the hand-held power tool, which is in particular formed from a plastic. It is also conceivable to attach the clamping neck to the housing of the hand-held power tool in a different material connection, for example by gluing, welding, etc. However, other configurations of the clamping neck and its attachment to the housing of the hand-held power tool that appear sensible to a person skilled in the art are also conceivable.
Es wird vorgeschlagen, dass der Spannhals von einem einer Bearbeitungsseite zugewandten Ende des Gehäuses in eine der Bearbeitungsseite abgewandte Haupterstreckungsrichtung des Gehäuses beabstandet angeordnet ist. Unter einem "einer Bearbeitungsseite zugewandten Ende des Gehäuses" soll insbesondere ein Endbereich des Gehäuses der Handwerkzeugmaschine verstanden werden, welcher in Haupterstreckungsrichtung der Handwerkzeugmaschine der Werkzeugaufnahme zugewandt angeordnet ist. Das der Bearbeitungsseite zugewandte Ende des Gehäuses umfasst eine Stirnseite, welche vorzugsweise zumindest zum Teil zumindest im Wesentlichen senkrecht, d.h. mit einer Abweichung kleiner 45°, vorzugsweise kleiner 20°, zur Haupterstreckungsrichtung steht und welche einen in Haupterstreckungsrichtung äußersten Bereich des Gehäuses der Handwerkzeugmaschine bildet. Unter "beabstandet angeordnet" soll in diesem Zusammenhang insbesondere verstanden werden, dass eine, insbesondere von einer Unterseite des Gehäuses gebildete Fläche zwischen der sich zumindest im Wesentlichen senkrecht zur Haupterstreckungsrichtung der Handwerkzeugmaschine erstreckenden Stirnseite des der Bearbeitungsseite zugewandten Endes der Handwerkzeugmaschine und zumindest einem Schnittpunkt einer Mantelfläche des Spannhalses und einem Vektor, der ausgehend von einer Rotationsachse der Ausgangswelle in Richtung zur Stirnseite parallel zur Haupterstreckungsrichtung verläuft, angeordnet ist, wobei eine Flächennormale der Fläche, welche vorzugsweise von der Unterseite des Gehäuses der Handwerkzeugmaschine gebildet ist, zumindest im Wesentlichen parallel zur Ausgangswelle der Getriebeeinheit verläuft. Dabei soll unter "im Wesentlichen" insbesondere verstanden werden, dass eine Abweichung einer Parallelität der Flächennormalen der von der Unterseite des Gehäuses gebildeten Fläche und der Ausgangswelle der Getriebeeinheit insbesondere weniger als 25°, vorzugsweise weniger als 15° und besonders bevorzugt weniger als 5° beträgt. Vorzugsweise ist der Spannhals insbesondere vollständig von der zumindest im Wesentlichen senkrecht zur Axialrichtung der Ausgangswelle verlaufenden Fläche, welche vorzugsweise von der Unterseite des Gehäuses gebildet ist, umschlossen. Durch die erfindungsgemäße Ausgestaltung kann eine besonders vorteilhafte Aufnahme der Zubehörbefestigungsvorrichtung an dem Spannhals erreicht werden.It is proposed that the clamping neck be arranged at a distance from an end of the housing facing a machining side in a main direction of extension of the housing facing away from the machining side. An “end of the housing facing toward a machining side” is to be understood in particular as an end region of the housing of the handheld power tool, which is arranged facing the tool holder in the main extension direction of the handheld power tool. The end of the housing facing the machining side comprises an end face which is preferably at least partially at least essentially perpendicular, i.e. with a deviation of less than 45°, preferably less than 20°, to the main direction of extent and which forms an outermost area of the housing of the hand-held power tool in the main direction of extent. In this context, "arranged at a distance" is to be understood in particular as meaning that a surface formed in particular by an underside of the housing between the end face of the end of the hand-held power tool that faces the machining side, which end face extends at least essentially perpendicularly to the main extension direction of the hand-held power tool, and at least one intersection point of a lateral surface of the clamping neck and a vector which, starting from a rotational axis of the output shaft, runs in the direction of the end face parallel to the main direction of extent, with a surface normal of the surface, which preferably extends from the underside of the housing of the hand-held power tool is formed, runs at least essentially parallel to the output shaft of the transmission unit. "Substantially" is to be understood in particular as meaning that a deviation of a parallelism of the surface normal of the surface formed by the underside of the housing and the output shaft of the transmission unit is in particular less than 25°, preferably less than 15° and particularly preferably less than 5° . In particular, the clamping neck is preferably completely enclosed by the surface which runs at least essentially perpendicularly to the axial direction of the output shaft and which is preferably formed by the underside of the housing. The configuration according to the invention enables the accessory attachment device to be accommodated on the clamping neck in a particularly advantageous manner.
Ferner wird vorgeschlagen, dass der Spannhals in einer Axialrichtung der Ausgangswelle eine Länge von zumindest 3 mm aufweist. In einer besonders bevorzugten Ausgestaltung der Erfindung weist der Spannhals in Axialrichtung der Ausgangswelle insbesondere eine Länge von zumindest 5 mm, vorzugsweise von zumindest 8 mm und besonders bevorzugt von zumindest 10 mm auf. Dadurch kann erreicht werden, dass die Zubehörbefestigungsvorrichtung auf vorteilhaft einfache und komfortable Weise von dem Benutzer der Handwerkzeugmaschine an dem Spannhals der Handwerkzeugmaschine befestigt werden kann.Furthermore, it is proposed that the clamping neck has a length of at least 3 mm in an axial direction of the output shaft. In a particularly preferred embodiment of the invention, the clamping neck has a length of at least 5 mm, preferably at least 8 mm and particularly preferably at least 10 mm in the axial direction of the output shaft. As a result, the accessory attachment device can be attached to the clamping neck of the hand power tool by the user of the hand power tool in an advantageously simple and convenient manner.
Erfindungsgemäß weist der Spannhals eine in Umfangsrichtung profilierte Mantelfläche auf, die dazu vorgesehen ist, eine Zubehörbefestigungsvorrichtung formschlüssig in Umfangsrichtung zu sichern. Unter einer "in Umfangsrichtung profilierten Mantelfläche" soll in diesem Zusammenhang insbesondere verstanden werden, dass zumindest eine Außenkontur des Spannhalses in einer Schnittansicht, senkrecht zur Axialrichtung der Ausgangswelle, zumindest teilweise, vorzugsweise vollständig von einer kreisförmigen Außenkontur abweicht. Die Außenkontur der Mantelfläche des Spannhalses ist erfindungsgemäß oval, mehreckig, epizykloidenförmig und/oder sternförmig ausgebildet. Durch die in Umfangsrichtung profiliert ausgebildete Mantelfläche des Spannhalses kann auf vorteilhaft einfache Weise eine Verdrehsicherung der Zubehörbefestigungsvorrichtung in Umfangsrichtung erreicht werden, wobei die Zubehörbefestigungsvorrichtung von dem Benutzer der Handwerkzeugmaschine vorzugsweise in zumindest zwei Positionen relativ zur Umfangsrichtung an dem Spannhals befestigt werden kann.According to the invention, the clamping neck has a lateral surface profiled in the circumferential direction, which is intended to positively secure an accessory attachment device in the circumferential direction. In this context, a "peripheral surface profiled in the peripheral direction" is to be understood in particular as meaning that at least one outer contour of the clamping neck in a sectional view perpendicular to the axial direction of the output shaft deviates at least partially, preferably completely, from a circular outer contour. According to the invention, the outer contour of the lateral surface of the clamping neck is oval, polygonal, epicycloid-shaped and/or star-shaped. The lateral surface of the clamping neck, which is profiled in the circumferential direction, can be used in an advantageously simple manner to prevent the accessory attachment device from rotating in the circumferential direction, with the accessory attachment device being removed by the user of the hand-held power tool can preferably be attached to the clamping neck in at least two positions relative to the circumferential direction.
Erfindungsgemäß weist der Spannhals eine in Axialrichtung profilierte Mantelfläche auf, die dazu vorgesehen ist, eine Zubehörbefestigungsvorrichtung formschlüssig in Axialrichtung zu sichern. Unter einer "in Axialrichtung profilierten Mantelfläche" soll in diesem Zusammenhang insbesondere verstanden werden, dass zumindest eine Außenkontur des Spannhalses in einer Schnittansicht, parallel zur Axialrichtung der Ausgangswelle, von einer Geraden abweicht und eine, insbesondere über eine reine Materialrauhigkeit und/oder Bearbeitungsungenauigkeit hinausgehende, Erhebung und/oder Vertiefung aufweist. Der Spannhals weist erfindungsgemäß eine Nut auf, welche entlang der Mantelfläche in Umfangsrichtung in einer senkrecht zur Axialrichtung der Ausgangswelle erstreckenden Ebene verläuft. Durch die in Axialrichtung profiliert ausgebildete Mantelfläche des Spannhalses kann eine vorteilhaft einfache Sicherung der Zubehörbefestigungsvorrichtung am Spannhals in zumindest eine Axialrichtung erreicht werden.According to the invention, the clamping neck has a lateral surface which is profiled in the axial direction and is intended to positively secure an accessory fastening device in the axial direction. In this context, a "surface profiled in the axial direction" is to be understood in particular as meaning that at least one outer contour of the clamping neck deviates from a straight line in a sectional view, parallel to the axial direction of the output shaft, and a Having collection and / or depression. According to the invention, the clamping neck has a groove which runs along the lateral surface in the circumferential direction in a plane extending perpendicular to the axial direction of the output shaft. An advantageously simple securing of the accessory attachment device on the clamping neck in at least one axial direction can be achieved by the lateral surface of the clamping neck, which is configured to be profiled in the axial direction.
Die Zubehörbefestigungsvorrichtung, insbesondere eine Handwerkzeugmaschinenzubehörbefestigungsvorrichtung, ist dazu vorgesehen, am Spannhals der Handwerkzeugmaschine befestigt zu werden und weist eine Befestigungseinheit und zumindest eine Zubehörkoppeleinheit auf. Unter einer "Zubehörkoppeleinheit" soll insbesondere ein Bereich der Zubehörbefestigungsvorrichtung verstanden werden, welcher speziell dazu vorgesehen ist, ein Zubehörelement aufzunehmen und/oder verliersicher an der Zubehörbefestigungsvorrichtung zu sichern. Das Zubehörelement kann insbesondere von einem Zusatzhandgriff, einem Abstandshalter, einem Führungsschlitten oder einem Tiefenanschlag gebildet sein. Es sind weitere, einem Fachmann als sinnvoll erscheinende Ausgestaltungen des Zubehörelements denkbar. Die Zubehörkoppeleinheit kann vorzugsweise ein Halteelement umfassen, das dazu vorgesehen ist, ein Zubehörelement lösbar an der Zubehörbefestigungsvorrichtung zu befestigen. Unter "lösbar" soll in diesem Zusammenhang insbesondere "zerstörungsfrei trennbar" verstanden werden. Besonders vorteilhaft ist das Zubehörelement werkzeuglos lösbar und/oder befestigbar. Es ist auch denkbar, dass die Zubehörkoppelstelle von einem Bereich der Zubehörbefestigungsvorrichtung gebildet ist, welcher dazu vorgesehen ist, das Zubehörelement stoffschlüssig aufzunehmen. Hierbei kann das Zubehörelement an die Stelle der Zubehörbefestigungsvorrichtung angeschweißt, angeklebt und/oder angelötet oder einstückig mit der Zubehörbefestigungsvorrichtung verbunden sein.The accessory fastening device, in particular a handheld power tool accessory fastening device, is intended to be fastened to the clamping neck of the handheld power tool and has a fastening unit and at least one accessory coupling unit. An "accessory coupling unit" is to be understood in particular as an area of the accessory attachment device which is specifically provided for receiving an accessory element and/or captively securing it on the accessory attachment device. The accessory element can in particular be formed by an additional handle, a spacer, a guide carriage or a depth stop. Other configurations of the accessory element that appear sensible to a person skilled in the art are conceivable. The accessory docking unit may preferably include a retainer adapted to releasably attach an accessory to the accessory attachment device. In this context, “detachable” is to be understood in particular as “non-destructively separable”. Particularly advantageously, the accessory element can be detached and/or attached without tools. It is also conceivable that the accessory coupling point is formed by an area of the accessory fastening device which is intended to receive the accessory element in a materially bonded manner. Here can the accessory element may be welded, glued and/or brazed at the location of the accessory attachment device or integrally connected to the accessory attachment device.
Es wird vorgeschlagen, dass die Befestigungseinheit zumindest einen Spannring aufweist. Unter einem "Spannring" soll in diesem Zusammenhang insbesondere ein Bauteil verstanden werden, welches dazu vorgesehen ist, an dem Spannhals der Handwerkzeugmaschine vorzugsweise form- und/oder kraftschlüssig befestigt zu werden. Der Spannring kann hierzu zumindest teilweise eine kreisförmige, ovale, mehreckige, epizykloidenförmige und/oder sternförmige Innenkontur aufweisen, die einen Aufnahmebereich begrenzt. Vorzugsweise ist die Innenkontur des Spannrings komplementär zur Außenkontur des Spannhalses ausgebildet. Durch diese Ausgestaltung der Zubehörbefestigungsvorrichtung mit dem Spannring der Befestigungseinheit kann eine vorteilhaft einfache Befestigung des Zubehörelements an der Handwerkzeugmaschine erreicht werden. Der Spannring kann vorzugsweise aus Metall gebildet sein, wodurch der Spannring vorteilhaft einfach und kostengünstig hergestellt werden kann. Es ist jedoch auch denkbar, den Spannring aus einem Kunststoff herzustellen, wodurch an den Spannring vorteilhaft einfach weitere Elemente angeformt werden können.It is proposed that the fastening unit has at least one clamping ring. In this context, a “clamping ring” is to be understood in particular as meaning a component which is intended to be fastened to the clamping neck of the hand-held power tool, preferably in a positive and/or non-positive manner. For this purpose, the clamping ring can at least partially have a circular, oval, polygonal, epicycloid-shaped and/or star-shaped inner contour, which delimits a receiving area. The inner contour of the clamping ring is preferably designed to complement the outer contour of the clamping neck. This configuration of the accessory fastening device with the clamping ring of the fastening unit allows the accessory element to be fastened to the hand-held power tool in an advantageously simple manner. The clamping ring can preferably be formed from metal, as a result of which the clamping ring can advantageously be produced simply and inexpensively. However, it is also conceivable to produce the clamping ring from a plastic, as a result of which further elements can advantageously be easily molded onto the clamping ring.
Des Weiteren wird vorgeschlagen, dass der Spannring federelastisch ausgebildet ist. Unter "federelastisch" soll in diesem Zusammenhang verstanden werden, dass der Spannring gegen eine Federkraft, die vorzugsweise vom Spannring aufgebracht wird, von einem Bediener verformt, vorzugsweise in Radialrichtung aufgeweitet werden kann, insbesondere um mehr als 2 mm und vorzugsweise um mehr als 5 mm, und anschließend selbsttätig in eine Ursprungsform zurückschnappt. Durch die federelastische Ausgestaltung des Spannrings kann der Spannring auf vorteilhaft einfache und unkomplizierte Weise an dem Spannhals der Handwerkzeugmaschine von dem Benutzer der Handwerkzeugmaschine befestigt werden. Alternativ oder zusätzlich kann der Spannring auch von zumindest einem zusätzlichen Spannelement gespannt und somit kraftschlüssig auf dem Spannhals der Handwerkzeugmaschine gehalten werden. Das zumindest eine Spannelement kann von einer Spannschraube und/oder vorzugsweise von einem Spannhebel gebildet sein. Es sind auch andere, dem Fachmann als sinnvoll erscheinende Ausgestaltungen des zumindest einem zusätzlichen Spannelements denkbar.Furthermore, it is proposed that the clamping ring is designed to be spring-elastic. In this context, "spring-elastic" should be understood to mean that the clamping ring can be deformed by an operator against a spring force, which is preferably applied by the clamping ring, and can preferably be expanded in the radial direction, in particular by more than 2 mm and preferably by more than 5 mm , and then automatically snaps back into an original shape. Due to the spring-elastic design of the clamping ring, the clamping ring can be fastened to the clamping neck of the hand-held power tool by the user of the hand-held power tool in an advantageously simple and uncomplicated manner. Alternatively or additionally, the clamping ring can also be clamped by at least one additional clamping element and thus held in a non-positive manner on the clamping neck of the hand-held power tool. The at least one tensioning element can be formed by a tensioning screw and/or preferably by a tensioning lever. Other configurations of the at least one additional tensioning element which appear sensible to a person skilled in the art are also conceivable.
Ferner wird vorgeschlagen, dass der Spannring in einer Umfangsrichtung profiliert ausgebildet ist. Unter "in einer Umfangsrichtung profiliert ausgebildet" soll in diesem Zusammenhang insbesondere verstanden werden, dass zumindest eine Innenkontur in einer Draufsicht auf den Spannring in einer Haupterstreckungsebene des Spannrings zumindest teilweise von einer kreisförmigen Innenkontur abweicht. Die Innenkontur des Spannrings kann insbesondere oval, mehreckig, epizykloidenförmig und/oder sternförmig ausgebildet sein. Vorzugsweise ist die Innenkontur des Spannrings der Zubehörbefestigungsvorrichtung zumindest im Wesentlichen komplementär zu der Außenkontur der in Umfangsrichtung profilierten Mantelfläche des Spannhalses der Handwerkzeugmaschine. Dadurch kann auf vorteilhaft einfache Weise eine Verdrehsicherung des Spannrings der Zubehörbefestigungsvorrichtung in Umfangsrichtung erreicht werden, wobei der Spannring der Zubehörbefestigungsvorrichtung von dem Benutzer der Handwerkzeugmaschine vorzugsweise in zumindest zwei Positionen relativ zur Umfangsrichtung an dem Spannhals befestigt werden kann.It is also proposed that the clamping ring be profiled in a circumferential direction. In this context, "profiled in a circumferential direction" is to be understood in particular as meaning that at least one inner contour in a plan view of the clamping ring in a main extension plane of the clamping ring deviates at least partially from a circular inner contour. The inner contour of the clamping ring can in particular be oval, polygonal, epicycloid-shaped and/or star-shaped. The inner contour of the clamping ring of the accessory attachment device is preferably at least essentially complementary to the outer contour of the lateral surface of the clamping neck of the hand-held power tool that is profiled in the circumferential direction. As a result, the clamping ring of the accessory fastening device can be secured against rotation in the circumferential direction in an advantageously simple manner, with the clamping ring of the accessory fastening device being able to be fastened to the clamping neck by the user of the hand-held power tool, preferably in at least two positions relative to the circumferential direction.
Ferner wird vorgeschlagen, dass der Spannring in einer Radialrichtung offen ausgebildet ist. Unter "offen" soll in diesem Zusammenhang verstanden werden, dass der Spannring Enden aufweist, welche in Umfangsrichtung voneinander beabstandet angeordnet sind. Dabei kann zwischen den Enden des Spannrings in Radialrichtung ein Durchgang vorliegen oder die Enden des Spannrings können in Radial- und/oder in Axialrichtung überlappend angeordnet sein. Durch diese Ausgestaltung des Spannrings kann eine einfache Montage und/oder Demontage erreicht werden. Dadurch kann ein Bedienkomfort für den Benutzer der Handwerkzeugmaschine vorteilhaft erhöht werden. Vorzugsweise kann durch diese Ausgestaltung des Spannrings erzielt werden, dass der Spannring in Radial- und Umfangsrichtung vorteilhaft einfach federelastisch deformiert, insbesondere aufgeweitet werden kann, sodass der Spannring vorteilhaft einfach in Axialrichtung oder in Radialrichtung auf den Spannhals der Handwerkzeugmaschine aufgeschoben werden kann. Dadurch kann ein Bedienkomfort für den Benutzer der Handwerkzeugmaschine besonders vorteilhaft erhöht werden.It is also proposed that the clamping ring is designed to be open in a radial direction. In this context, “open” is to be understood as meaning that the clamping ring has ends which are arranged at a distance from one another in the circumferential direction. There can be a passage between the ends of the clamping ring in the radial direction, or the ends of the clamping ring can be arranged so that they overlap in the radial and/or axial direction. With this configuration of the clamping ring, simple assembly and/or disassembly can be achieved. As a result, ease of use for the user of the hand-held power tool can advantageously be increased. This configuration of the clamping ring can preferably be achieved in that the clamping ring can advantageously be simply elastically deformed, in particular expanded, in the radial and circumferential direction, so that the clamping ring can advantageously simply be pushed onto the clamping neck of the hand-held power tool in the axial direction or in the radial direction. As a result, ease of use for the user of the hand-held power tool can be increased in a particularly advantageous manner.
Ferner wird ein System mit einer Handwerkzeugmaschine, mit einer ersten Zubehörbefestigungsvorrichtung und mit zumindest einer weiteren, von der ersten Zubehörbefestigungsvorrichtung differierenden Zubehörbefestigungsvorrichtung, welche zusätzlich oder alternativ zu der ersten Zubehörbefestigungsvorrichtung an der Handwerkzeugmaschine befestigbar ist, vorgeschlagen. Durch das erfindungsgemäße System kann eine vorteilhaft hohe Flexibilität der Handwerkzeugmaschine für den Benutzer der Handwerkzeugmaschine erreicht werden, wodurch der Bedienkomfort vorteilhaft erhöht werden kann.Furthermore, a system with a handheld power tool, with a first accessory attachment device and with at least one other accessory attachment device that differs from the first accessory attachment device and can be attached to the handheld power tool in addition or as an alternative to the first accessory attachment device is proposed. With the system according to the invention, an advantageously high degree of flexibility of the hand-held power tool can be achieved for the user of the hand-held power tool, as a result of which the ease of use can be advantageously increased.

An einem Ende der Ausgangswelle 12, welches aus dem Gehäuse 36 der Handwerkzeugmaschine herausragt, ist die Werkzeugaufnahme 14 mit dem darin gehaltenen Einsatzwerkzeug 16 angeordnet. Die Werkzeugaufnahme ist über die Ausgangswelle 12 der Getriebeeinheit oszillierend antreibbar. Zudem umfasst die Handwerkzeugmaschine eine nicht näher dargestellte, von einem Elektromotor gebildete Antriebseinheit und eine nicht näher dargestellte Getriebeeinheit. Die Getriebeeinheit ist dazu vorgesehen, eine Rotationsbewegung der Antriebseinheit in eine Oszillationsbewegung 10 zu übersetzen. Die Getriebeeinheit weist die Ausgangswelle 12 auf. In einem der Werkzeugaufnahme 16 in Haupterstreckungsrichtung 40 der Handwerkzeugmaschine abgewandten Bereich weist die Handwerkzeugmaschine ein Stromkabel 42 zur Stromversorgung der Antriebseinheit auf.The

Zwischen dem Gehäuse 36 der Handwerkzeugmaschine und der Werkzeugaufnahme 14 ist in Axialrichtung 22 der Spannhals 18 angeordnet. Der Spannhals 18 erstreckt sich in einer Umfangsrichtung 20 vollständig um die Ausgangswelle 12 herum und ist in Umfangsrichtung 20 geschlossen und durchgängig ausgebildet. Der Spannhals 18 ist einstückig an dem Gehäuse 36 der Handwerkzeugmaschine angeformt. Der Spannhals 18 weist eine Länge in Axialrichtung 22 von 10 mm auf. Ein Durchmesser des Spannhalses 18 entspricht im Wesentlichen einem Durchmesser des Stützflansches 46. Unter "im Wesentlichen" soll in diesem Zusammenhang insbesondere verstanden werden, dass eine Differenz der Durchmesser des Spannhalses 18 und des Stützflansches 46 zueinander insbesondere weniger als 15%, vorzugsweise weniger als 10% und besonders bevorzugt weniger als 5% des größten Durchmessers beträgt. Zudem weist der Spannhals 18 eine in Axialrichtung 22 profilierte Mantelfläche 24 auf, welche dazu vorgesehen ist, eine Zubehörbefestigungsvorrichtung formschlüssig in Axialrichtung 22 zu sichern. Die Profilierung der Mantelfläche 24 ist von einer Nut 54 gebildet, welche sich in Umfangsrichtung 20 des Spannhalses 18 erstreckt.The clamping

Zudem weist die Zubehörbefestigungsvorrichtung die Zubehörkoppeleinheit 28 auf. Die Zubehörkoppeleinheit 28 ist an einer den Spannfortsätzen 58 abgewandten Seite des Spannrings 30 angeordnet und stoffschlüssig mit dem Spannring 30 verbunden. Die Zubehörkoppeleinheit 28 ist von einem Halteelement 62 gebildet. Das Halteelement 62 weist eine Befestigungsausnehmung 64 auf, die sich tangential zu einer Umfangsrichtung 32 des Spannrings 30 und senkrecht zu den Spannfortsätzen 58 erstreckt. In die Befestigungsausnehmung 64 des Halteelements 62 kann das Zubehörelement 56 eingeschoben werden. Das Zubehörelement 62 wird dann mit einer Zubehörbefestigungsschraube 66 in dem Halteelement 62 kraftschlüssig und/oder formschlüssig befestigt.In addition, the accessory attachment device has the

Der Spannring 30a ist in einer Radialrichtung 34a des Spannrings 30a offen ausgebildet. Der Spannring 30a weist zwei Spannfortsätze 58a auf. Die Spannfortsätze 58a sind einstückig an dem mehreckig ausgebildeten Befestigungsbereich 60a des Spannrings 30a angeformt. Die Spannfortsätze 58a erstrecken sich in Radialrichtung 34a des Spannrings 30a von dem Befestigungsbereich 60a nach außen. Die Spannfortsätze 58a des Spannrings 30a verlaufen in einem ersten, dem Befestigungsbereich 60a des Spannrings 30a zugewandten Bereich parallel zueinander. In einem zweiten, dem Befestigungsbereich 60a des Spannrings 30a abgewandten Bereich der Spannfortsätze 58a verlaufen die Spannfortsätze 58a sich voreinander entfernend in einer gebogenen Linie nach außen. Dieser zweite Bereich der Spannfortsätze 58a bildet einen Führungsbereich 72a. Bei einem Montagevorgang kann der Spannring 30a der Befestigungseinheit 26a der Zubehörbefestigungsvorrichtung in Radialrichtung 34a auf den Spannhals 18a der Handwerkzeugmaschine aufgeschoben werden. Dabei wird eine, von einem Benutzer aufgebrachte Kraft in Radialrichtung 34a in eine tangential zu einer Umfangsrichtung 20a verlaufende Kraft umgelenkt. Diese tangential zur Umfangsrichtung 20a verlaufende Kraft bewirkt eine federelastische Auslenkung der Spannfortsätze 58a und damit eine Aufweitung des Spannrings 30a in Umfangsrichtung 32a.
