The invention relates to a power drill, having a tool-clamping device that is coupled to a drive motor via a drive shaft and a torque clutch equipped with a transmission element. The torque clutch has a clutch-adjusting ring that cooperates at least indirectly with at least one clamping element that exerts a prestressing force on the transmission element. An end of the drive shaft oriented toward the tool-clamping device is guided in a bearing that axially fixes the drive shaft in a drilling or screwdriving position and axially releases the drive shaft in an impact drilling position. The bearing cooperates with a bearing holder, which moves the bearing axially via a user-actuatable actuating element. According to the invention, the actuating element is coupled to an adjusting element that axially fixes the transmission element and axially releases the bearing in the impact drilling position and axially releases the transmission element and axially fixes the bearing in the drilling or screwdriving position. |
