Abstract (en)
[origin: EP2412478A2] The clamping device has a fixed clamping jaw (1), a movable clamping jaw (2), and a drive for adjusting the movable clamping jaw relative to the fixed clamping jaw. The drive has a threaded spindle (7) and a reinforcement mechanism (8) to strengthen the clamping force. The threaded spindle is formed as a telescopic shaft, where the reinforcement mechanism is formed to exert a pulling force on the movable clamping jaw.
