Abstract

The invention relates to a hand-held pulling and compression device and a mechanical force amplifier for a hand-held pulling and compression device for driving pulling and pressing tools. The hand-held pulling and compression device for driving interchangeable tools has a drive unit comprising a battery-operated electric motor, a first screw drive with a first threaded spindle mounted rotatably on a housing body and a threaded nut mounted rotatably on the first threaded spindle and non-rotatably on the housing body via a bearing unit, and a coupling unit connectable to a tool holder for transmitting tensile and compressive forces resulting from the direction of rotation of the first threaded spindle from the first threaded nut to the tool holder. In order to provide a mechanical force amplifier for a hand-held pulling and compression device and a hand-held pulling and compression device which can be easily and flexibly adapted to different work operations, it is provided that the mechanical force amplifier has a connecting section for detachably fixing the mechanical force amplifier to a connection section of the housing body of the hand-held pulling and compression device and a tool connection for pulling and compression tools.
