摘要

The tool has a lower and an upper plate connected by fastening screws (a). The lower plate (10) has slots (11) with an L-shaped clamping/tensioning plate (12) sliding in them. A plate end vertically below the slots is freely accessible and defines a clamping surface (121), while the other plate end defines a control surface (122). This has an opening (123) acting with the lower end of an N-shaped control bar (13). The upper plate (14) has an aperture (142) with blind bores (141), each of which acts with an upper end of the bar. This plate also has a central upper end acting with a stud key, which drives it.
