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.

An improved technique relating to mounting of a battery in an impact tool which has a handle configured to move with respect to a tool body. A hammer drill has a body, a handle part and a battery mounting part. The handle part is configured to slide with respect to the body under a biasing force of a coil spring. The battery mounting part has a plurality of mounting parts. At least one of the mounting parts of the battery mounting part is connected to the handle part and slides together with the handle part with respect to the body during operation.

An impact tool has a body and a striking mechanism that drives a tool accessory in a prescribed longitudinal direction. The body has a first body element on which the striking mechanism is provided, and a second body element. The first body element and the second body element are connected via a cushioning mechanism. A vibration reducing mechanism is provided on the first body element.

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 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.

A percussion tool includes a housing having a top end, a bottom end, a front end, and a rear end. The housing defines a barrel portion, a handle portion opposite the barrel portion, and a motor housing portion between the barrel portion and the handle portion. The percussion tool also includes an electric motor positioned within the motor housing portion and a percussion mechanism driven by the motor and including a striker supported for reciprocation in the housing. The striker defines a striker axis in a reciprocating direction. The percussion tool further includes a battery receptacle supported by the housing and a battery pack removably coupled to the battery receptacle for providing power to the motor. The battery pack and the battery receptacle define a battery axis extending longitudinally through the battery pack and battery receptacle. The striker axis and the battery axis are parallel.

Hand-held power tool having a tool fitting for holding a striking and rotating tool on a working axis, an electric motor, an impact mechanism, which has a striker moved periodically along the working axis, and having a rotary drive, which drives a spindle bearing the tool fitting in a rotating manner about the working axis, the rotary drive having a step-down eccentric gear mechanism, connected to the electric motor, and the spindle being coupled to the eccentric gear mechanism.

A hammer/drill includes a housing, a motor with armature shaft, a spindle rotatably mounted about a longitudinal axis in the housing, a tool holder rotatingly driven by the motor about the longitudinal axis, a hammer mechanism for generating impacts acting on the tool holder, a drive shaft coupleable with the armature shaft, and a switching arrangement to switch between drilling, hammer drilling, and hammering modes. The switching arrangement comprises a selector and coupling part axially displaceable on the drive shaft between lower and upper positions, coupling and decoupling the drive shaft to the armature shaft respectively. The coupling part includes a sleeve comprising a flange, and the selector comprises a fork for engaging a lower part of the flange. A protuberance engages a drive member of the selector to pivot the selector when the spindle is rotated, engaging over only a portion of the rotational movement of the spindle.

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.

A reciprocating tool includes a motor, a motion converting mechanism, a body housing, an inner housing, a support body, and a counterweight. The motion converting mechanism is operably coupled to a motor shaft and is configured to convert rotation into a linear reciprocating motion along a driving axis. The inner housing is within the body housing and houses at least a portion of the motion converting mechanism. The support body is originally separate from the inner housing and is attached to the inner housing in the body housing. The counterweight is operably coupled to the motion converting mechanism and is configured to be driven by the motion converting mechanism. The counterweight is supported by the support body to be pivotable around a pivot axis that extends in a direction orthogonal to the driving axis. At least a portion of the counterweight is housed in the inner housing.
