Clamping device

Abstract

The invention relates to a clamping device 1 comprising a clamping head 4 with a drive wheel 5 for transmitting a torque to an output element 2 which is engaged with the drive wheel 5 in a torque-locking manner and with a locking device 11 with a locking element 12 which can be set into several functional positions, by which a torque transmission to the drive wheel 5 is only possible in one direction of rotation when in a torque transmission functional position, further comprising a clamping lever 6 connected to the clamping head 4 and aligned in a radial direction to the axis of rotation of its drive wheel 5 for manually applying a torque acting on the drive wheel 5 via the interposition of the locking element 12 and comprising a drive train with a rotary tool connection 10, 10.1 for driving the drive wheel 5 by means of a rotary tool, in particular a power-driven one.A special feature is that the drive train for transmitting a torque from a rotary tool to the drive wheel 5 of the clamping device 1 has a tool drive wheel 7 which provides the rotary tool connection 10, 10.1 or is torque-locked to it and whose axis of rotation is spaced apart from that of the drive wheel 5, through which the drive wheel 5 of the clamping device 1 is driven as an output wheel of the drive train with gear reduction, and that the locking element 12 of the locking device 11 acts on the tool drive wheel 7 in a torque transmission function position.
