The arrangement has a front stand (4) and a rear stand (5) that are secured at a support (8) over base plates (6, 7). The base plate of the front stand comprises a semicircular or wedge shaped clamping projection for fastening the base plate of the front stand with a counter bearing at the support. The clamping projection engages and extends over a portion of the base plate of the front stand at specific height and forms a complementary formed recess with the counter bearing. A clamping piece (15) is actuated at the base plate of the front stand. |
