摘要： The invention relates to a tool device which is suitable for use with a machine tool, in particular a hand guided machine tool, having a driving device moving, in particular in an oscillating manner, around a driving axis. The tool device has an attachment device which allows it to be fastened on a machine tool such that its driving axis and an axis of rotation of the tool substantially coincide. The attachment device, for absorbing the driving force, has at least two driving area regions, which are spaced apart from said tool axis of rotation and each has a plurality of surface points. The tangent planes to said surface-area points are inclined in regard to an axial plane, which encloses the tool axis of rotation. Furthermore, said tangent planes are inclined regard to a radial plane which extends perpendicularly to the tool axis of rotation. This means that the torque introduced into the tool device by the machine tool, via the driving device, is reliably absorbed.

摘要： A quick clamping device for a machine tool, in particular for a hand-held machine tool, includes at least one clamping device that is moveably mounted in particular on an output spindle of the machine tool that can be rotationally driven about an output shaft of the machine tool, at least for axially securing a tool device, in particular an insert tool, on the output spindle of the machine tool. The quick clamping device includes at least one movement securing unit having at least one movement securing element arranged in particular on the clamping device, which is provided for a movement of the tool device, in particular in a rotary drive position, and/or for securing the tool device.

摘要： The invention relates to a machine tool, in particular a hand held machine tool, which has a tool-accommodating device which can be moved, in particular in oscillating fashion, about a drive axis, in order to retain a tool device on the machine tool. The tool-accommodating device has at least one clamping device, at least one retaining device and at least one locking device. The retaining device can be moved from at least one first, open position into at least one second, closed position. It is also the case that the retaining device can be forced by a clamping force, by way of the clamping device, preferably in the closing direction from said first, open position in the direction of said second, closed position. The locking device can be moved between at least one first, locking position and at least one second, unlocking position. It is possible here for said locking device to block movement of the retaining device in at least one locking position. A force applied to the locking device directly or indirectly by the tool device moves said locking device from one of said locking positions into one of said unlocking positions. This allows the tool device to be inserted particularly quickly and straightforwardly into the machine tool.

摘要： The invention relates to a machine tool, in particular a hand held machine tool, which has a tool receiving device that is movable, in particular in an oscillating manner, around an output shaft (2). The tool receiving device is designed to hold a tool device on the machine tool in such a manner that the output shaft and a tool rotation axis substantially coincide. The tool receiving device has at least one torque transmission region (9) and a holding device (4a, 4b). In order to transmit a driving force to the tool device, the torque transmission region has at least two output area regions (9a) that are arranged at a distance from said output shaft and each have a multiplicity of surface points. Here, the tangent planes to said surface points are inclined in regard to an axial plane which includes said output shaft. Furthermore, the tangent planes are inclined in regard to a radial plane which extends perpendicularly to the output shaft. In this way, the output torque is transmitted reliably to the tool device by the machine tool via the tool receiving device.
