A mobile machine tool (10), namely a manually-operated machine tool or semi-stationary machine tool, for machining a workpiece (W), wherein the machine tool has a plate-like guide element (30) with a guide surface (32) for guiding the machine tool on the workpiece (W) or the workpiece (W) on the machine tool, wherein the machine tool has a drive unit (11) with a drive motor (13) for driving a tool holder (14) arranged on the drive unit (11), wherein the drive unit (11) is, by means of a bearing arrangement (35), mounted adjustably on the guide element (30) in order to adjust at least two adjustment positions (S0, S1, S2) of the tool holder (14) relative to the guide surface (32) in which a work tool (15) arranged on the tool holder (14), penetrates into the workpiece (W), to different penetration depths. The machine tool (10) is provided with a height measuring device (95) for detecting a height (H) of the workpiece (W), wherein the height corresponds to a distance between an upper side (WO) of the workpiece which is to be penetrated by the work tool (15) and a workpiece underside (WU) of the workpiece (W) opposite the upper side of the workpiece (W).

Electric hand-held power tool with a housing and a tool fitting, the hand-held power tool having a TOF sensor, which is arranged on the or in the housing and the field of view of which is oriented in the direction of the tool fitting, so that the TOF sensor can detect a tool to be fitted in the tool fitting.

A power tool including a housing and a motor assembly arranged to rotate a cutting tool. The motor is mounted in the housing. At least one guide post is slidably mounted to the housing. The power tool includes a base fixed to the guide post. A depth adjustment mechanism is arranged to adjust the distance the cutting tool projects through the base. The depth adjustment mechanism has a depth rod adjustably mounted to the housing and arranged to engage the base when the housing is plunged towards the base. The depth adjustment mechanism also has a depth adjustment knob mechanically coupled to the depth rod and moving the depth rod with respect to the housing. The depth adjustment mechanism further has a locking knob for selectively locking the depth rod. One of the depth adjustment knob and the locking knob at least partially is nested within the other.

A rotary hammer includes a housing, a first motor supported by the housing and defining a first motor axis, a second motor supported by the housing and defining a second motor axis that is coaxial with the first motor axis, and a spindle coupled to the first motor for receiving torque from the first motor, causing the spindle to rotate. The rotary hammer further includes a reciprocation mechanism operable to create a variable pressure air spring within the spindle. The reciprocation mechanism includes a piston configured to reciprocate within the spindle in response to receiving torque from the second motor, a striker that is selectively reciprocable within the spindle in response to reciprocation of the piston, and an anvil that is impacted by the striker when the striker reciprocates towards the tool bit. The anvil imparts axial impacts to the tool bit.

An electric device, including a body, a working module, a control module, and a radar, where the radar includes: an antenna unit, configured to transmit and receive an electromagnetic wave signal; a transmitting unit, configured to generate an electromagnetic wave signal transmitted by the antenna unit; a receiving unit, configured to process an electromagnetic wave signal received by the antenna unit; and a control unit, connected to the transmitting unit and the receiving unit; where the antenna unit, the transmitting unit, the receiving unit, and the control unit are integrated in one chip. The described chip-type radar is small in size and low in cost, the detection accuracy is improved through the combination of multiple radars, and the influence on appearance design is minimized.

The disclosure relates to a system, comprising a vacuum apparatus having a vacuum apparatus housing and having at least one vacuum apparatus mains socket, the at least one vacuum apparatus mains socket being attached to the vacuum apparatus housing. According to the disclosure, the system additionally comprises a plug-in module, having a plug-in module communication unit, an electrical plug-in module mains plug unit, and a current control unit, which is designed to control an electrical current between the plug-in module and the vacuum apparatus.
