A system includes first and second power tools that each have a percussion mechanism, a motor, and a transmission. The transmission includes a striking mechanism and is configured to transfer a driving motion of the motor to an insert tool held in a tool holder. The transmission has a guide tube that is identical in some regions along a working axis and accommodates a striker. The guide tube is rotatably coupled to the motor by a first transmission unit. The striker is driven to linearly oscillate by a piston of a second transmission unit. A ratio between a diameter of the tool holder and a diameter of the guide tube is 1.8 times greater in the first power tool than in the second power tool. A striking energy of the second power tool is mechanically reduced compared to a striking energy of the first power tool.

A nail punching machine for driving in or pulling out rail spikes comprises a driving mechanism, which is driven by means of an electric drive motor. The electric drive motor is supplied with electric power by means of an accumulator. The nail punching machine is held by an operator by means of at least one handle.

An electric power tool dust collection system includes: a hammer drill, to which a dust suction bit is mounted; a dust collection device mounted to the hammer drill and including a suction portion (introduction port), a dust collection motor, a dust collection fan rotated by drive of the dust collection motor to generate a sucking force in the introduction port, and a dust collection portion (dust box) that stores powder dust suctioned from the introduction port; and exhaust flow paths (exhaust flow path and tubular flow path) respectively formed in the hammer drill and the dust collection device to lead exhaust that has passed through the dust box to a high-temperature portion (output portion) of the hammer drill.

A power tool includes a tool body, a motor, a handle, at least one biasing member, and at least one guide part. The handle is connected to the tool body to be pivotable and to be movable in at least a front-rear direction relative to the tool body. The handle includes a cover part covering a portion of the tool body and a grip part extending in a cantilever manner from the cover part. The at least one biasing member biases the tool body and the handle away from each other in the front-rear direction. The at least one guide part includes a first portion disposed on a portion of the tool body covered by the cover part, and a second portion disposed on the cover part of the handle and connected to the first portion to be movable in at least the front-rear direction relative to the first portion.

A work tool includes a motor, a driving mechanism, a body housing and a handle. The driving mechanism is configured to perform an operation of linearly reciprocating the tool accessory along a driving axis extending in a front-rear direction. The handle includes a grip part extending substantially in an up-down direction, and a battery-mounting part provided on a lower side of the grip part. An upper end portion of the handle is connected to a rear end portion of the body housing via an elastic member so as to be movable relative to the body housing. A lower end portion of the handle is connected to the rear end portion of the body housing so as to be rotatable relative to the body housing, around a rotation axis extending in a left-right direction. The rotation axis is located on a lower side of the battery-mounting part.

The disclosure relates to a machine tool, in particular a hand-held machine tool, comprising a housing and an electronics module, wherein the electronics module has a position-determining unit and a communications unit, wherein the electronics module can be supplied with energy via an at least partially independently formed energy unit. According to the disclosure, the electronics module is accommodated in an electronics housing, wherein the electronics housing is coupled to the housing of the machine tool.

A rotary hammer includes a motor, a manipulation member, a main switch, a mode-switching member, a first locking member and a second locking member. The first locking member is configured to selectively lock the manipulation member in an OFF position according to a switching position of the mode-switching member. The second locking member is configured to selectively lock the manipulation member in an ON position according to the switching position of the mode-switching member. The first locking member is allowed to lock the manipulation member in the OFF position both when a hammer mode has been selected and when a drill mode has been selected. The motor is allowed to be driven in a state in which the manipulation member is locked in the ON position by the second locking member only when the hammer mode has been selected.
