For this purpose, a guide hole 46 is provided in the tie rod 40 , in which the guide 52 of the safety rod 50 is guided. The length of the guide hole 46 defines the extraction path of the safety bar 50 and at its two ends 47a, 47b defines the rest position and the extraction position of the safety bar 50 .
