Abstract (en)
[origin: EP0674053A2] The coupling has a clamp screw screwed into a threaded aperture in the arm of the moveable seat block (5). The screw is turnably held in a counter pressure plate. The plate is fixed in the seat and fastening device. It is formed as a bolt plate, which is pivoted into a release position. The seat block is connected to a pretensioned spring (14), and is moved into the release position by the force of the spring. The seat block is moveable downwards at an angle to the connection line between the two seat blocks. The angle between connection line and movement direction is approx. 15 degrees .
