Abstract
A reciprocating hand saw (), having a motor housing () and a gearbox () that receive a battery-operated direct-current motor () with a motor shaft having a shaft end () and a gear (), respectively, which gear—as known per se in reciprocating saws—is connected to the shaft end in a way driven to rotate and whose gear input pinion () converts the rotation of the motor shaft end () into an up-and-down motion of a push rod () that carries a sawblade (), can be produced economically and is especially sturdy because the gear () and its gearbox () originate in a reciprocating saw that can be operated by alternating current, and because between the shaft end () and the gear input pinion (), a multi-stage coupling (), disposed in a manner fixed against relative rotation for transmitting torque, comprises parts that can be easily separated from one another.
