The invention relates to a handheld tool, in particular a handheld saw, with an electric drive motor (), a serially switched gearbox (), and a movement converter () that converts the driven movement of the gearbox () into an axial to-and-fro movement of a lifting element () for driving a tool (), in particular a saw blade, inside a housing (). The gearbox () and the movement converter () are combined into a gear unit (). The gear unit () is within a robust, bending- and deformation-resistant gear housing (), which is in turn inside the housing (). The housing () is made of flexible plastic.

Handheld power tool, in particular handheld power saw

A universal saw capable of being employed as a jigsaw or sabre saw, having a housing containing a drive train that includes an electric drive motor and a motion converter that converts the rotary motion of the drive motor into a reciprocating working motion of the saw blade movably guided in the housing, and having a wear-resistant base plate for supporting the universal saw on the work piece to be machined can be adapted with particular ease to the optimally desired intended use as a jigsaw or as a sabre saw in that on the one hand, the base plate () can be rigidly locked in a definite, first operating position in relation to the housing of the universal saw () in which position, the direction of the working movement of the saw blade () is perpendicular to the plane of the base plate () and on the other hand, outside of this operating position, the base plate () can be variably adjusted in its angular position in relation to the direction of the working movement.

Universal saw

A reciprocating hand saw with a housing has a motor, a gearbox with a lifting rod for moving a saw blade mounted thereon up and down, and a base plate on which the housing is mounted, capable of carrying particularly easy-to-handle spare saw blades by the fact that the housing has an opening into which a magazine-like, longitudinal saw blade receptacle is capable of being inserted in a detachable, captive manner, and a part of the saw blade receptacle serving as grip projects outwardly.
