A switching device for an electric tool includes: an output shaft unit disposed in an outer casing, having an output shaft, a movable ratchet wheel mounted such that the movable ratchet wheel is movable axially along the output shaft and is non-rotatable therewith; a fixed ratchet unit having a fixed ratchet wheel sleeved around the output shaft and having ratchet teeth for meshing with ratchet teeth of the movable ratchet wheel; and a function switch unit having a switch ring mounted rotatably on the casing. Rotation of the switch ring about its axis results in rotation of pawls within the switch ring, thereby driving the pawls about its pivot points and meshing and/or non-meshing of the pawls with external ratchet teeth of the fixed ratchet wheel, thereby switching the output shaft among a continuous rotation, rotation in a single direction and simultaneously providing an axial impact during the rotation.

A hand-held power tool includes an output spindle and a user guidance unit configured to be actuated by a user. The hand-held power tool further includes a drive unit configured to rotationally drive the output spindle. The drive unit can be changed over between a first direction of rotation and a second direction of rotation in order to drive the output spindle in the first or second direction of rotation. The power tool further includes a communication interface configured to communicate with the user guidance unit. The communication interface is further configured to receive, from the user guidance unit, changeover instructions for changing over the drive unit between the first direction of rotation and the second direction of rotation in an application-specific manner.

A hand-held power tool includes a drive unit configured to drive an insertion tool in at least one non-percussive operating mode. The drive unit includes a percussion mechanism for percussive driving of the insertion tool in an associated percussion mode. The hand-held power tool further include a user guidance unit configured to be actuated by a user and a communication interface configured to communicate with the user guidance unit and to receive, from the user guidance unit, changeover instructions for changing over the drive unit between the at least one non-percussive operating mode and the associated percussion mode in an application-specific manner.

A power tool communication system including an external device including a first controller configured to transmit, via wireless communication to a power tool, configuration data including a work light duration parameter value and a work light brightness parameter value. The power tool includes a housing, a brushless direct current (DC) motor, a trigger, a work light, a wireless communication circuit configured to wirelessly communicate with the external device to receive the configuration data, and a second controller configured to control a work light duration of the work light based on the work light duration parameter value, and control a work light brightness of the work light based on the work light brightness parameter value.

A hand-held power tool includes a drive unit that has at least one gear-shift transmission which can shift at least between two different gear steps; a striking mechanism that can be activated for performing a striking mode is associated with the drive unit; a shifting unit is provided for shifting the gear-shift transmission between the at least two different gear steps and/or for activating/deactivating the striking mechanism, and a communication interface is provided for communicating with a user-actuated user guiding unit and is configured to receive shifting instructions from the user guiding unit in order for the transmission to shift in an application-specific manner between the two different gear steps and/or for the striking mechanism to be activated/deactivated.

An electric working machine in one aspect of the present disclosure includes a motor; an acceleration sensor; a load-determiner; a filter part having a cutoff frequency; and a filter-property setting part. The filter part removes an unwanted signal component from a detection signal from the acceleration sensor based on the cutoff frequency and inputs, to the load-determiner, the detection signal with the unwanted signal component removed. The filter-property setting part changes the cutoff frequency of the filter part such that a cutoff frequency in a high-speed rotation mode is higher than a cutoff frequency in a low-speed rotation mode.

An adapter for a power tool includes a housing, a tool-side connector, and a battery-side connector in electrical communication with each other. The tool-side connector is configured to couple to a power tool, and the battery-side connector is configured to couple to a battery pack. The adapter also includes a communication interface configured to couple with an external device, and a controller. The controller is configured to determine a state of the power tool, operate in a data transmission mode when the power tool is in the idle state, operate in a pass-through mode when the power tool is in the active state, and switch between the data transmission mode and the pass-through mode based on the state of the power tool.

A hammer drill comprises a drive mechanism including a spindle, a first ratchet coupled for co-rotation with the spindle, a second ratchet rotationally fixed to the housing, and a hammer lockout mechanism adjustable between a first mode and a second mode. The hammer drill further comprises a clutch adjustable between a first state and a second state. The hammer drill further comprises a collar rotatably coupled to the housing and movable between a first rotational position in which the hammer lockout mechanism is in the first mode and the clutch is in the first state, a second rotational position in which the hammer lockout mechanism is in the second mode and the clutch is in the first state, and a third rotational position in which the hammer lockout mechanism is in the second mode and the clutch is in the second state.

A hand tool device has a tool spindle and a hammer mechanism which includes a hammer and at least one curve guide driving the hammer at least during a hammer drilling operation. The tool spindle has at least one bearing surface on which the hammer is movably supported in at least one operating state.
