Abstract: 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.

Abstract: An electric hand-held power tool, in particular a power drill or screwdriver, is disclosed, which has a chuck (14) for a tool, a drive spindle (13) which drives the chuck (14) and protrudes with a spindle head (131) into a recess (15) embodied in the chuck (14), and connecting means, operative between the spindle head (131) and the recess (15), for connecting the drive spindle (13) and the chuck (14) in a manner fixed against relative rotation. For achieving a connection between the chuck (14) and the drive spindle (13) that is very simple from a production standpoint and hence economical and that even in drive spindles with a reversible direction of rotation assures reliable, non-rescindable torque transmission, the connecting means have axially extending cutting edges (26), embodied on the spindle head (131), that cut into the wall of the recess (15) when the chuck (14) is being slipped onto the spindle head (131) (FIG. 2).
