The locking device is provided for locking an output device and has at least one locking element for supporting at least one radial clamping force. According to a proposed embodiment, the locking element is provided to fasten and/or axially secure at least one component. ## Claims ### Claim 1 A hand-held power tool device, comprising: an output device including an output shaft; a locking device configured to lock the output shaft, the locking device including: at least one locking element embodied as a clamping ring and configured to support at least one radial clamping force; at least one clamping element embodied as a clamping roller; and at least one catch element configured to entrain the at least one clamping element; and a bearing unit configured to support the output shaft, the bearing unit including a bearing component, wherein the bearing component and the clamping ring are arranged in at least one first common plane extending perpendicular to a rotation axis of the output shaft; wherein the at least one clamping roller, the clamping ring, and the at least one catch element are arranged in at least one second common plane extending perpendicular to the rotation axis of the output shaft and parallel to the at least one first common plane. ### Claim 2 (depends on 1) The hand-held power tool device as recited in claim 1, wherein the bearing component is arranged completely within an axial extension of the clamping ring. ### Claim 3 (depends on 1) The hand-held power tool device as recited in claim 1, wherein the bearing component and the at least one clamping roller are arranged completely within an axial extension of the clamping ring. ### Claim 4 (depends on 1) The hand-held power tool device as recited in claim 1, wherein the at least one clamping roller and the clamping ring are arranged in at least one second common plane extending perpendicular to the rotation axis of the output shaft and parallel to the at least one first common plane. ### Claim 5 (depends on 1) The hand-held power tool device as recited in claim 1, wherein the bearing component is fixedly connected to an inner surface of the clamping ring. ### Claim 6 (depends on 1) The hand-held power tool device as recited in claim 1, wherein the bearing component is fixedly connected to the inner surface of the clamping ring by means of a press-fit connection. ### Claim 7 (depends on 1) The hand-held power tool device as recited in claim 1, wherein the bearing unit is embodied as a roller bearing, wherein the bearing component is embodied as an outer bearing ring of the roller bearing. ### Claim 8 (depends on 7) The hand-held power tool device as recited in claim 7, wherein the roller bearing includes an inner bearing ring which is directly supported on the output shaft. ### Claim 9 (depends on 8) The hand-held power tool device as recited in claim 8, wherein the inner bearing ring is fixedly connected to the output shaft by means of a press-fit connection. ### Claim 10 (depends on 8) The hand-held power tool device as recited in claim 8, wherein the inner bearing ring is configured to act as an axial stop element for the at least one clamping roller. ### Claim 11 (depends on 1) The hand-held power tool device as recited in claim 1, wherein the bearing unit is embodied as a slide bearing, wherein the bearing component includes a slide bearing surface which is directly supported on the output shaft. ### Claim 12 (depends on 11) The hand-held power tool device as recited in claim 11, wherein the bearing component is embodied in one piece with the clamping ring such that the clamping ring is directly supported on the output shaft. ### Claim 13 (depends on 11) The hand-held power tool device as recited in claim 11, wherein the bearing component is fixedly connected to the inner surface of the clamping ring. ### Claim 14 (depends on 11) The hand-held power tool device as recited in claim 11, wherein the bearing component is fixedly connected to the inner surface of the clamping ring by means of a press-fit connection. ### Claim 15 (depends on 1) The hand-held power tool device as recited in claim 1, wherein the bearing unit is configured to support the output shaft at an end oriented toward a drive motor. ### Claim 16 (depends on 1) The hand-held power tool device as recited in claim 1, wherein the at least one catch element is part of a catch device. ### Claim 17 (depends on 1) The hand-held power tool device as recited in claim 1, wherein the catch device is embodied in one piece with a planet carrier of a planetary gear. ### Claim 18 (depends on 1) The hand-held power tool device as recited in claim 1, wherein the at least one clamping roller is arranged between the clamping ring and the output shaft. ### Claim 19 (depends on 18) The hand-held power tool device as recited in claim 18, wherein the at least one clamping roller is directly supported on the output shaft. ### Claim 20 (depends on 1) The hand-held power tool device as recited in claim 1, wherein the at least one clamping roller is arranged adjacent to the bearing component in an axial direction of the output shaft. ### Claim 21 (depends on 1) The hand-held power tool device as recited in claim 1, wherein the at least one clamping ring is at least partially made of a sintered material. ### Claim 22 (depends on 1) The hand-held power tool device as recited in claim 1, further comprising: a housing unit in which the at least one clamping ring is supported with a radial play of less than 0.1 mm. ### Claim 23 (depends on 1) The hand-held power tool device as recited in claim 1, further comprising: a housing unit that is injection-molded around the clamping ring. ### Claim 24 (depends on 1) A hand-held power tool having a hand-held power tool device as recited in claim 1.
