A machine tool clamping device for clamping a laminar machining tool to a tool holder that is eccentrically movably mounted includes at least one clamping unit with at least one movably mounted clamping element. The machine tool clamping device also includes at least one slotted link movement unit configured to move the clamping element in at least one operating state so as to generate tensile stress in the laminar machining tool.

Machine tool clamping device

A battery pack for locking with a power tool with at least one movable locking bar has at least a front recess and a rear recess located after the front recess in the direction of a relative motion between the battery pack and the power tool, the recesses are configured as detent grooves, and the recesses are differently shaped and are offset transversely to the direction of motion; and a power tool locks with the battery pack.

Device for locking electrical devices, in particular power tools, with battery packs for power supply

The invention relates to a device for locking electrical devices () with battery packs () for power supply, in which the electrical devices () have one movable locking bar () and the battery packs () have at least two recesses (), and upon locking, the recesses () are located one after the other in the direction of a relative motion between the electrical device () and the battery pack (), and after locking, the locking bar () engages one of the recesses (). It is provided that the recesses () are differently shaped or of different dimensions or are offset transversely to the direction of motion; and that in different combinations of electrical devices () and battery packs (), the shape, dimensions and/or offset of the recesses () are each adapted to the shape, dimensions or position of the locking bar () in such a way that the locking bar () engages either only the front recess () or only the rear recess () or successively the front recess and then the rear recess (, respectively).

A device for locking a power tool and a rechargeable battery pack that is insertable in a guide of the power tool has a locking bar installable on a housing of the power tool and held in locking engagement with the rechargeable battery pack via spring force, a release mechanism that acts on the locking bar for manually releasing the locking bar from the locking engagement, the locking bar and the release mechanism forming a lever that is pivotally supportable in a rocker pivot on the housing, the locking bar being fixedly held via spring force and a recess formed at a top side of the rechargeable battery pack and is releasable by pivoting the lever from the locking engagement via a compression force applied to the release mechanism, which extends upwardly across a front base end of the housing.
