摘要： A coupling member for an electric power tool is provided. The coupling member can keep a hanging member being held, even when a holding portion of the tool for holding the hanging member breaks. A coupling member for an electric power tool is configured to hook a hanging member to an electric power tool main body and can fasten the electric power tool main body therein, when one of its parts opens or closes. Further, this coupling member can be attached to the electric power tool main body with the electric power tool main body fastened therein or removed therefrom. Further, the hanging member can be hooked to the coupling member.

摘要： A driving tool with a mechanical spring uses urging force from a striking spring as driving force and switches its operation mode. The tool includes a striking driver to strike a fastener, a striking spring urging the driver in a driving direction, a contact arm movable to a retracted position in a counter-driving direction in response to pressing against a workpiece, a trigger movable to an on-position in response to user operation, and a mode selector switch to switch the operation mode between continuous drive mode and single drive mode. A driving operation is performed in the continuous drive mode in response to the contact arm moving to the retracted position and the trigger moving to the on-position in any order, and in the single drive mode in response to the contact arm moving to the retracted position and the trigger moving to the on-position in the stated order.

摘要： A reciprocating tool includes a housing, a support body, a slider, a motor, a driving mechanism, a first biasing member, a manipulation member and a first change mechanism. The housing has a first axis that defines a front-rear direction of the reciprocating tool. The support body is supported within the housing. The slider is supported by the support body to be linearly movable. The driving mechanism is operably coupled to the slider and configured to reciprocally move the slider relative to the support body using power of the motor. The first change mechanism is operably coupled to the manipulation member and configured to selectively enable and disable the first biasing member to bias the slider in response to manipulation of the manipulation member. When biasing of the slider by the first biasing member is enabled by the first change mechanism, the first biasing member biases the slider downward.

摘要： An electric work machine in one aspect of the present disclosure includes an electric power input terminal, a motor, a circuit board, a first heat dissipation plate, and a second heat dissipation plate. The circuit board includes a first surface and an electronic circuit on the first surface. The electronic circuit controls supply of AC power to the motor. The electronic circuit includes an electronic component that generates Joule heat. The first heat dissipation plate is spaced from the first surface by a first distance in parallel to the first surface. The second heat dissipation plate is spaced from the first surface by a second distance in parallel to the first surface. The second heat dissipation plate is thermally coupled with the first heat dissipation plate. The second distance is smaller than the first distance.
