- EP 0 904 896 A2 discloses a grinding machine tool holder for a hand-held worm grinding machine.
- the angle grinder has a drive shaft that has a thread on the tool side.
- the grinding machine tool holder has a driver and a clamping nut.
- the driver is pushed onto an collar of the drive shaft with an assembly opening and clamped non-positively against a bearing surface of the drive shaft via the clamping nut.
- the driver has a collar that extends in the axial direction on the tool side and has recesses on its outer circumference radially on two opposite sides that extend in the axial direction to a base of the collar.
- a groove extends in each case against the drive direction of the drive shaft on the outer circumference of the collar.
- the grooves are closed against the drive direction of the drive shaft and taper axially from the recesses against the drive direction of the drive shaft.
- the grinding wheel has a hub with an assembly opening in which two opposite, radially inward-pointing tongues are arranged.
- the tongues can be more axial
- a stopper which is movably mounted in an opening in the axial direction. In a working position with the grinding wheel pointing downwards, the stopper is deflected by gravity axially in the direction of the grinding wheel, closes the groove in the direction of the recess and blocks a movement of the tongue located in the groove in the drive direction of the drive shaft.

It is also possible for the insert tool to be positively fixed in a second direction, for example in the circumferential direction, by a component separated from the catch element by the form-fitting fixing of the insert tool with the detent element m, for example m radial direction.
- the movably mounted latching element can be designed in various forms that appear useful to those skilled in the art, for example as an opening, projection, pin, bolt, etc., and can be arranged on the insert tool and / or on the driving device.
- the latching element can itself be movably mounted in a component in a bearing point, for example in a flange of the driving device or in a tool hub of the insert tool.
- the latching element can also advantageously be firmly connected to a component that is movably mounted in a bearing point, positively and / or cohesively, or can be made in one piece with it, for example with a component mounted on the drive shaft or with a tool hub of the insert tool.
- the driving device can be at least partially designed as a removable adapter part or can be non-positive, positive and / or

- a non-positive locking is also conceivable, in particular in the case of the proposed tool holder, in which only small torques have to be absorbed by the locking device during assembly and disassembly of the insert tool. In the event of an accidental actuation of the actuation button during operation, less wear can be achieved compared to a positive locking device.
- the latching element can be released from its latched position with a release button and, in particular, moved against the spring element, an independent loosening of the latching connection, for example by a braking torque, can be reliably avoided and safety can be increased. Operation of the insert tool in two circumferential directions can be made possible in principle, and the ease of assembly and disassembly of the insert tool can be increased.
- the actuation button and the release button of the locking device are designed in one piece. Additional components, weight, assembly effort and costs can be saved and, in particular, the comfort can be increased and operation can be simplified.
