Abstract

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 …
