Abstract
A power-driven hand tool comprises a drive spindle adapted to drive a tool, that can be driven to oscillate about its longitudinal axis, which tool can be fixed on a retaining section of the dive spindle by a securing element, and further comprises a displacing device that serves to displace the securing element between a releasing position in which the securing element can be released from the drive spindle and a clamping position in which the securing element is clamped on the retaining section by a spring element, the securing element comprising a clamping shaft adapted to be inserted into the securing element, which is axially fixed in the drive spindle for clamping the tool in the clamping position, and which can be detached in the releasing position. For clamping of the tool a split chuck is provided which is clamped on the retaining section by the securing element in the clamped position and is connected with the retaining section in form-locking engagement.
