主权项 1. A hand-held power tool comprising: a transmission housing; a tool clamping unit having a plurality of clamping jaws and an adjusting sleeve; and a rotatable torque-adjusting ring configured to adjust a torque clutch, the torque-adjusting ring including a first end in a first plane that is at a first axial position and a second end that is in a second plane that is at a second axial position, wherein the torque clutch includes an element that is arranged on the transmission housing and the torque-adjusting ring is connected to the element of the torque clutch such that the maximum transmittable torque can be adjusted by the torque-adjusting ring, wherein at least when the tool clamping unit is in a completely open position, an axial rear end of the clamping jaws is, with respect to an axial direction, rearward of the first plane and the second plane is, with respect to the axial direction, rearward of the axial rear end of the tool clamping unit, wherein the axial rear end of the clamping jaws is accommodated in a chamber that is: open in the axial direction toward a front thereof;delimited in a radial direction toward an outside thereof by the adjusting ring; anddelimited axially toward a rear thereof by an annular wall of the adjusting ring that extends radially inward, the annular wall being positioned, with respect to the axial direction, rearward of an axial forward end of the transmission housing,wherein an axial stop embodied in the form of a securing ring is provided with respect to the axial direction, rearward of the first plane, and prevents an axial movement of the adjusting ring past the axial stop.
