Handheld machine tool having a spindle-locking device

A handheld machine tool, comprising:

• a drive motor;
• a spindle-locking device having a blocking element embodied as an annular clamping ring and at least one spindle cylinder;
• and
• a tool housing, in which the drive motor is situated for driving a drive element having at least one clamping surface, to which the spindle-locking device is assigned, wherein:
• the at least one spindle cylinder is configured to be clamped in a spindle-lock operation of the spindle-locking device between the at least one clamping surface of the drive element and the blocking element in order to prevent the drive element from rotating relative to the tool housing, wherein the at least one spindle cylinder is configured to directly contact the at least one clamping surface of the drive element, and
• the spindle-locking device includes an impingement element that impinges on the at least one spindle cylinder with a specified force in a direction of the at least one clamping surface of the drive element,
• wherein the impingement element includes a viscoelastic ring for impinging on the at least one spindle cylinder,
• wherein a transmission housing defines a groove, and the viscoelastic ring is situated at least in sections directly in the groove of the transmission housing,
• wherein the viscoelastic ring is arranged adjacent to the clamping ring in a longitudinal axis of the drive element such that the viscoelastic ring is arranged at a first axial position of the longitudinal axis and the clamping ring is arranged at a second axial position of the longitudinal axis different than the first axial position.
