The invention is based on a tool receptacle, in particular for a hand-held angle grinding machine ( 10 ) or a circular power saw, having a slaving device ( 12, 14, 300 ), by way of which an insert tool ( 16 ) can be operatively connected to a drive shaft ( 18 ), and having a locking device ( 20 ), b
The invention is based on a tool receptacle, in particular for a hand-held angle grinding machine ( 10 ) or a circular power saw, having a slaving device ( 12, 14, 300 ), by way of which an insert tool ( 16 ) can be operatively connected to a drive shaft ( 18 ), and having a locking device ( 20 ), by way of which, with an actuation button ( 22 ), the drive shaft ( 18 ) can be locked upon mounting and/or removal of the insert tool ( 16 ).It is proposed that the actuation button ( 22 ) is operatively connected in the direction of rotation ( 32, 34 ) to the drive shaft ( 18 ), and by way of the actuation button ( 22 ), for locking the drive shaft ( 18 ), at least one first part ( 24 ), operatively connected in the direction of rotation ( 32, 34 ) to the drive shaft ( 18 ), can be connected to a second part ( 26 ), which is rotationally fixed with respect to a rotational axis of the drive shaft ( 18 ).

1. A tool receptacle for a hand-held angle grinding machine or a circular power saw, comprising a slaving device for operatively connecting an insert tool to a rotatable drive shaft: a locking device for looking with an actuation button the drive shaft upon mounting and removal of the insert tool, the actuating button being operatively connected in a direction of rotation of the drive shaft to the drive shaft and being operative for connecting at least one first part which is operatively connected in the direction of rotation to the drive shaft, to a second part which is rotationally fixed with respect to a rotational axis of the drive shaft. 2. A tool as defined in claim 1, and further comprising at least one detent element for operatively connecting the insert tool to the slaving device and supported movably counter to a force of a spring element, the at least one detent element snapping into place in an operating position on the insert tool and fixing the insert tool by positive engagement. 3. A tool as defined in claim 2, wherein at least one element selected from the group consisting of the detent element and a component movably supported with the detent element is connectable by the actuation button to the second part which is rotationally fixed with respect to the rotational axis of the drive shaft, while the drive shaft is lockable in a circumferential direction. 4. A tool as defined in claim 2, wherein at least one element selected from the group consisting of the detent element and the component movably supported by the detent element is connectable by positive engagement to the second part that is rotationally fixed with respect to the rotational axis of the drive shaft. 5. A tool as defined in claim 3, wherein at least one element selected from the group consisting of the detent element and the component movably supported with the detent element is connectable by frictional engagement to the second part that is rotationally fixed with respect to the rotational axis of the drive shaft. 6. A tool as defined in claim 2, wherein the detent element is displaceable in an axial direction of the shaft counter to the force of the spring element. 7. A tool as defined in claim 2; and further comprising an unlocking button with which the detent element is releasable from its detent position. 8. A tool as defined in claim 7, wherein the actuation button and the unlocking button are formed integrally with one another. 9. A tool as defined in claim 2, wherein the at least one detent element extends in an axial direction of the shaft and is secured in a component that is supported displaceably on the drive shaft counter to the force of the spring element. 10. A tool as defined in claim 2; and further comprising a disc-shaped component on which the at least one detent element is formed integrally. 11. A tool as defined in claim 1; and further comprising a disc-shaped component on which the first part operatively connected to the drive shaft in the direction of rotation of the drive shaft is integrally formed. 12. A tool as defined in claim 1; and further comprising a disc shaped component; and at least two elements provided for fixation of the insert tool in an axial direction of the shaft and integrally formed with the disc-shaped component.
