Power tool
There is provided a power tool in which impact applied to a power transmission portion can be mitigated to thereby suppress components constituting the power transmission portion from being deformed and damaged. The power tool includes a brushless motor 3 having a rotation shaft portion 31 rotatable about a rotation axis A1, a housing 2 accommodating therein the brushless motor 3, a power transmission portion 6 configured to receive a rotation force of the rotation shaft portion 31 and to transmit a driving force based on the rotation force, and a driven portion 7 configured to be driven by receiving the transmitted driving force. The rotation shaft portion 31 is supported by the housing 2 so as to be movable relative to the housing 2 in an axial direction of the rotation axis A1.

Blade clamp for reciprocating saw
A blade clamp, for use with a power tool having a reciprocating spindle, includes a cover rotatably coupled to the spindle and a detent received within a bore of the spindle. The detent is movable in a radial direction relative to a longitudinal axis of the spindle to adjust the blade clamp between a locked configuration and an unlocked configuration. The cover is rotatable between a first rotational position relative to the spindle coinciding with the locked configuration, and a second rotational position relative to the spindle coinciding with the unlocked configuration. The blade clamp further includes a sleeve in which the detent is slidably received. The sleeve includes a non-corrosive material for inhibiting corrosion of the detent.
RECIPROCATING TOOL HAVING ORBIT FUNCTION
A reciprocating power tool may include a driving system driving a reciprocating mechanism. A selection mechanism provides for selection of a linear mode of operation or at least one orbital mode of operation. Motion of a reciprocating shaft of the reciprocating mechanism may be guided by a guide bracket fixed in the housing and an orbit bushing movably coupled in the housing. The guide bracket may include at least one guide slot having a contoured guide surface that guides the motion of the corresponding end portion of the reciprocating shaft. The contoured guide surface may guide the corresponding end portion of the reciprocating shaft in a corresponding direction relative to the longitudinal centerline of the at least one guide slot during an out stroke and a return stroke of the reciprocating stroke.
Hand-held power tool
A hand-held power tool, in particular a saber saw, having at least one holding unit for fastening the hand-held power tool to a holding device, in particular to an arresting cable and/or carabiner clip. The holding unit includes at least one receiving opening for receiving the holding device, and at least one damping element for damping a force transferred from the holding device to the hand-held power tool, in particular to a housing of the hand-held power tool. The damping element includes an at least substantially elastic element that at least partially encloses the receiving opening and receives in a form-fitting manner a fastening part delimiting the receiving opening.
Jigsaw
A power tool includes a housing and a handle coupled to the housing. The handle is configured to be gripped by an operator to manipulate the power tool. The power tool also includes a drive system supported in one of the housing or the handle. The drive system includes a frame, a motor at least partially supported by the frame, and a transmission driven by the motor. The transmission is at least partially supported by the frame. The frame is composed of a non-electrically conductive material.
JIGSAW
A jigsaw including a housing, a handle extending transverse from the housing in a direction of a handle axis, a battery selectively coupled to the handle, a foot plate coupled to the housing and configured to contact a workpiece, and a drive assembly powered by the battery. The drive assembly includes a motor, a fan, a transmission driven by the motor, and an output spindle driven by the transmission and coupled to a cutting blade. The jigsaw also includes a frame supported within the housing which supports the motor and the transmission. The frame includes a shroud surrounding at least a portion of the fan and an air chute in fluid communication with the shroud that together direct an airflow produced by the fan toward a cutting area adjacent the cutting blade. The jigsaw also includes a baffle that is selectively moveable into the air chute to redirect the airflow away from the cutting blade.

Reciprocating tool
A reciprocating tool includes a motor, a reciprocating member, and a crank mechanism. The motor is disposed in a housing. The reciprocating member projects from the housing. The crank mechanism converts rotation of a rotation shaft of the motor into reciprocation of the reciprocating member. The crank mechanism rotates around an axis in a lateral direction by rotation transmission from the rotation shaft, and the crank mechanism includes a crank member having an eccentric pin, a connecting rod coupling the eccentric pin to the reciprocating member, and a balancer coupled to the eccentric pin, and the balancer is supported by the eccentric pin alone in the housing.
