A reciprocating tool includes a housing, a spindle having an end configured to receive a saw blade, and a blade clamp mechanism supported on the spindle and configured to attach the saw blade to the spindle. The blade clamp mechanism includes a locking member movable relative to the spindle between a locked position and an unlocked position. The blade clamp mechanism also includes an actuating member that is rotatable relative to the spindle between an engaged position and a released position. The actuating member defines a gripping surface with ridges and includes a first tab and a second tab, each of the first tab and the second tab protruding radially from the outer gripping surface.

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.

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 reciprocating saw includes a housing defining a motor housing portion, and a motor positioned in the motor housing portion, the motor having a motor output shaft defining a rotational axis, and a motor activation switch within the motor housing portion and adjacent the motor. The reciprocating saw also includes a transmission is positioned downstream of the motor and has a sawbar connectable to a saw blade. The transmission converts a rotational input provided by the motor shaft to a reciprocating output of the sawbar along a reciprocating axis that is either coaxial or parallel with the rotational axis.

A sliding cutting machine (1) includes: slide bars (51); a slide base (52), which slides along the slide bars; and a cutting-machine main body (10), which is swingable in an up-down direction about an up-down swing (pivot) shaft (10a) provided on the slide base. The cutting-machine main body includes: an output shaft (37) extending in an axial direction orthogonal to the slide bars and mounting a cutting tool (11); an electric motor (23) between the cutting tool and the slide bars when the cutting tool is vertical, and located more upward than the slide bars; and a motive-power transmitting part (30) transmitting the driving force of the electric motor to the output shaft. The motive-power transmitting part is between the cutting tool and the slide bars and upward of the slide bars when the cutting-machine main body is at a top dead center.

A method of assembling a gearcase cover assembly of a reciprocating saw. The method includes providing a gearcase cover with a cylindrical opening and a receiving portion, providing a shaft with a yoke affixed to the shaft, inserting a first end of the shaft into the cylindrical opening and rotating the shaft such that a second end of the shaft sits in the receiving portion.

A reciprocating saw includes a casing, a power assembly, a transmission assembly, a reciprocating assembly, a swing assembly, and a balance weight. The transmission assembly includes a first transmission member that is capable of being driven by the power assembly to rotate around a first axis. The swing assembly includes a floating support member configured to drive the reciprocating assembly to perform an orbital motion. The first transmission member is provided with a cam surface configured to be in contact with the floating support member to drive the floating support member to move in an up-and-down direction parallel to the first axis. The balance weight is provided with an escape opening, and the escape opening is disposed on a path on which the floating support member moves in the up-and-down direction.
