Switching device for a hammer drill and hammer drill comprising a switching device

A handheld power tool has a tool holder for holding a tool, and a grip housing for holding and guiding the handheld power tool. A relative motion of the tool holder and the grip housing can be transmitted as a switching motion to a microswitch, which switches a drive unit on and off. The tool holder and the grip housing can be moved relative to one another in a direction of rotation, and the switching motion thus comprises a rotary motion of the grip housing.

Handheld power tool, in particular a power drill or screwdriver

A reciprocating saw has a locking element () for axially fixing the saw blade () in a fastening device, wherein a release device () is provided, with which the locking element can be displaced into its release position against the spring force of an adjusting spring. A component (), acting upon the locking element, of the release device is arranged, with respect to the plane of the saw blade, on the same side as the locking element.
