Description

Hand-held power tool Technical Field The invention relates to a hand-held power tool, in particular a hammer drill. Background DE 103 21 869 A1 describes a hammer drill with a replaceable tool holder. Disclosure of Invention The invention relates to a hand-held power tool having a housing in which a drive unit and an impact mechanism unit are arranged, and having a tool receptacle interface which is designed for releasably connecting the hand-held power tool to a tool receptacle, wherein the tool receptacle is designed as a stirring basket receptacle (R hrkorbaufnahme). The invention proposes that the hand-held power tool have a user interface via which at least one hammer drill mode and a stirring mode can be set. Advantageously, the hand-held power tool can thus be optimally adapted to the purpose of use. The hand-held power tool can be designed as a plug-in hand-held power tool or as a battery-operated hand-held power tool that can be connected to a battery pack for power supply. A hand-held power tool is understood in the present context to mean, in particular, a tool for machining a workpiece by means of an electrically driven insert tool. A typical hand-held power tool is in this context a hand-held or vertical drilling machine, a screwdriver, a percussion drill, a hammer drill or similar power tool. The tool receiving portion is in particular configured for releasably securing a plug-in tool. The tool receiver which is releasably connected by the tool receiver interface is in particular designed in such a way that the user can change the tool receiver without tools or with the aid of tools. Different tool receiving portions are known to those skilled in the art. For example, tool receptacles in the form of quick-grip drill chucks for hammer drills or in the form of SDS-plus hammer chucks are known. The tool receiving part interface has force-locking and/or form-locking elements which can be releasably connected to corresponding force-locking and/or form-locking elements of the tool receiving part. The housing of the hand-held power tool is at least partially, in particular completely, embodied as an outer housing. The housing may be constructed in one piece or in multiple pieces. The housing is at least partially, in particular completely, made of plastic. Furthermore, the housing of the hand-held power tool may have an inner housing which is at least partially, preferably completely, surrounded by an outer housing. The hand-held power tool preferably has a drive unit with an electric motor. The electric motor may be configured as a direct current motor or an alternating current motor. The commutation of the motor can be performed electronically or by means of carbon brushes. The motor is rotatably mounted in a housing of the hand-held power tool about a motor axis. The drive unit or the motor can transmit the drive movement to the tool receiver or the insertion tool via the transmission unit. The impact mechanism unit may be configured, for example, as a pneumatic impact mechanism or as an intermittent impact mechanism. The pneumatic impact mechanism may be configured, for example, as an eccentric impact mechanism or as a pendulum impact mechanism. The striking mechanism has, in particular, a guide tube in which the striker and/or the piston are received in a linearly movable manner. The piston is preferably configured to be driven in a linear oscillation manner by an eccentric impact mechanism or a pendulum impact mechanism. The transmission unit is in particular designed such that the insertion tool connected to the tool receiving portion can be driven rotationally about the working axis and/or in a linear oscillating or striking manner along the working axis. The user interface may be constructed directly or indirectly. A direct user interface is understood to be a user interface in which settings are made by the user directly by input. It is conceivable here to set the stirring mode by a single parameter, for example the rotational speed of the motor or the tool receiver or the stirring time, or by a combination of several parameters, for example the rotational speed of the motor or the tool receiver and the stirring time. An indirect user interface is understood to be a user interface in which a user operation or a state of the hand-held power tool is sensed and the hand-held power tool is automatically set on the basis of the determined operation or the determined state. For example, the hand-held power tool may have one or more sensors, by means of which a user operation or a state of the hand-held power tool can be sensed. For example, the hand-held power tool can have a sensor in the form of a camera, by means of which the tool receiver or a plug-in tool connected thereto can be sensed. It is also conceivable that a sensor can sense or scan an identification unit or a bar code, by means of which a single parameter or a plurality of parameters can be set in combination. The indirect user int
