A pneumatic hammer has a conversion mechanism with a rotatable input member coupled to the motor and adapted to convert a rotational movement of the input member into a reciprocating movement of an output member. The input member is formed as a first carrier which supports a first planet gear. A first sun gear is coaxially arranged with the first carrier, and is rotatingly driven by the drive motor. A first ring gear is movable parallel to the first axis of rotation between a first position and a second position. A second gear is rotatable around a second axis of rotation parallel to the first axis of rotation. The second gear meshingly engages with the first ring gear when the first ring gear is in the second position, and is disengaged from the first ring gear when the first ring gear is in the first position.

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 mode and a second mode. The hammer drill further comprises a detent radially movable between a locking position and an unlocking position, and a collar movable between a first rotational position in which the hammer lockout mechanism is in the first mode and a second rotational position in which the hammer lockout mechanism is in the second mode. In the first mode the detent is positioned such that the spindle is moveable relative to the housing. In the second mode the detent is positioned such that the spindle is prevented from moving relative to the housing.

A hand-guided power tool, having a housing and a tool holder disposed on a drive shaft. The drive shaft is rotatably supported in the housing in at least one first bearing that is disposed in at least some portions in the vicinity of a face end of the housing oriented toward the tool holder. Between the first bearing and the tool holder, a detent mechanism for impact generation for the drive shaft is embodied.

A power tool including a brushless motor having a sensor circuit board has higher durability. The power tool includes a housing, a brushless motor including a rotor having a rotational shaft, a stator, and a sensor circuit board fixed to the stator and having a rotation detecting element that detects rotation of the rotor, and receiving the rotational shaft through the sensor circuit board, and a bearing held in the housing and supporting the rotational shaft. The bearing is located to overlap the rotation detecting element in an axial direction of the rotational shaft.

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.

A hammer drill includes a housing, a first ratchet fixed to the housing, a spindle rotatably supported by the housing about an axis, and a second ratchet coupled for co-rotation with the spindle. The second ratchet is engageable with the first ratchet in response to rearward displacement of the spindle to impart a hammering action on the spindle. The hammer drill further includes a thrust bearing having an arm extending away from the axis, and a selector ring having a post extending toward the arm. The selector ring is rotatable between a first position in which the post is engageable with the arm to limit the rearward displacement of the spindle and prevent engagement of the first and second ratchets, and a second position in which the post is misaligned with the arm to permit the rearward displacement of the spindle and engagement of the first and second ratchets.

In a hand-held power tool including a gear for driving an output shaft, which is situated in an assigned gear housing, and including a mode-setting unit for setting the operating mode for an impact drilling mode, a drilling mode, or a screwing mode, the mode-setting unit including a rotatable actuating element and a rotatable setting element coupled to the rotatable actuating element. The setting element is coupled, at least in one operating mode, to a transmission element which is mounted on the gear housing and is axially displaceable on the gear housing in a screwing position assigned to the screwing mode and is axially fixed on the gear housing in impact drilling and drilling positions assigned to the impact drilling and drilling modes. The actuating element and the setting element are formed as one piece from plastic.

An adapter for a power tool including 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.

Disclosed is a gear adjusting device for a gearbox of an impact drill, comprising a front gearbox housing, a torsional cover, a reduction mechanism and a tripping mechanism which comprises annular adjusting screws, tripping columns and a tripping cushion. Each tripping column is sleeved with a compression spring with two ends respectively connected to the bottom of a corresponding adjusting screw and a corresponding tripping column. The torsional cover is in threaded drive connection with each adjusting screw. The lower end of each tripping column is connected with the reduction mechanism. The tripping cushion is slidably connected to the front gearbox housing along the vertical direction. A cushion locking structure is disposed between the torsional cover and the front gearbox housing. The tripping cushion can be locked and fixed by the cushion locking structure when the torsional cover is rotated anticlockwise, and then the tripping cushion cannot move vertically.
