A reciprocating tool includes a housing, a first tubular member, a slider, a second tubular member and a lock member. The first tubular member is pivotable around a first axis and has a single first protrusion protruding radially inward. The second tubular member is disposed in the first tubular member, is coupled to a first end portion of the slider to be pivotable around a second axis, and has a single second protrusion protruding radially outward. The second tubular member has a protruding portion configured to allow the lock member to move from a lock position to an unlock position. The single first protrusion is configured to engage with the single second protrusion and cause the second tubular member to pivot when the first tubular member pivots. The single second protrusion is provided on a portion of the second tubular member other than the protruding portion.

A reciprocating tool includes a reciprocation conversion mechanism disposed in a casing neck, a saw blade connected to the reciprocation conversion mechanism, a shoe, and a shoe adjustment mechanism. The shoe adjustment mechanism has a cover plate connected to the reciprocation conversion mechanism and a slide pin. The shoe has a support and a guide plate pivotably connected to the support. The guide plate is disposed between the cover plate and the reciprocation conversion mechanism. The guide plate has a slide groove parallel to a direction of reciprocation. The slide pin passes through the slide groove. In a locked position of the shoe adjustment mechanism the slide pin is engaged in the slide groove and the guide plate is locked by the slide pin. In an unlocked position the slide pin is disengaged from the slide groove and the guide plate is slidable in the direction of reciprocation.

A modular handheld electric tool system comprises a handle, a motor module and a tool head. The handle includes a handle housing with an elongate portion configured to provide a grip, a handle electrical coupling on the handle housing, a circuit including a tool switch in the handle housing, the tool switch connected between a power supply and the handle electrical coupling. The motor module including a motor casing that holds an electric motor, a motor electrical coupling on the motor casing that is complementary to the handle electrical coupling and electrically connected to the electric motor, and a rotary output mounted to the motor casing and driven by the electric motor. At least one tool head is releasably attachable both to the motor module via a tool-less tool-head-to-motor mechanical coupling, and to the handle via a tool-less tool-head-to-handle mechanical coupling, the tool head including an accessory and tool body wherein, to supply torque to the accessory from the electric motor, a rotary input mounted to the tool body engages the rotary output of the motor module.

A hand-held power tool includes an SDS tool receiver and a tool housing. The SDS tool receiver includes at least one vacuuming-off channel and is configured to receive an exchangeable insert tool such that the at least one vacuuming-off channel enables removal of dust produced during operation of the exchangeable insert tool with a workpiece. The tool housing includes at least one drive unit configured to drive the exchangeable insert tool.

A power tool includes a housing, a power output element for outputting power, a motor for driving the power output element to output power, and a surface light source device for providing illumination. The surface light source device is mounted on the housing and the surface light source device includes a light exit surface allowing the surface light source device to emit light.

The disclosure provides a work tool having an electric motor, a power transmission means that receives motive power from the electric motor and transmits the motive power to a tip tool, a gear housing for accommodating at least a portion of the power transmission means, weights swingably supported on the gear housing, and coil springs that function as an urging means for urging the weights such that the weights are located at an initial neutral position, wherein the weights and the coil springs are provided respectively on the two sides of the gear housing so as to put the power transmission means therebetween, and a rotational support axle is provided that functions as a connecting means for connecting the weights provided on both sides of the gear housing so as to connect the weights such that the weights swing integrally.

A power tool including a housing having a handle configured to be grasped by a user, a motor supported by the housing, a driving gear rotated by the motor, and a driven gear engaging the driving gear to be rotated by the driving gear about a rotation axis. The power tool also includes a pin extending from the driven gear and offset from the rotation axis and a spindle having a yoke coupled to the pin to translate rotation of the driven gear into reciprocating motion of the spindle. A notch is formed in an outer periphery of the yoke to provide clearance for the driving gear as the spindle is driven by the pin.

Providing a reciprocating tool capable of reducing vibrations generated during operations and improving work performance and processing precision. A reciprocating tool includes a transmission gear part 61 and a counter weight part 62. The transmission gear part 61 includes a bevel gear 611 and a weight 611A. The bevel gear 611 is rotatable in a first direction about an axis B by receiving a drive force of a motor 3. The weight 62A is rotatable in a second direction opposite to the first direction about the axis B by receiving the drive force of the motor 3. A center of gravity 61G of the transmission gear part 61 and a center of gravity 62G of the counter weight part 62 are separated farthest from a blade mounting part 8 when the blade mounting part 8 is positioned in a rearward position. The center of gravity 61G of the transmission gear part 61 and the center of gravity 62G of the counter weight part 62 are closest to the blade mounting part 8 when the blade mounting part 8 is positioned in a forward position.
