摘要

In the rapid exchange device (1) a securing bolt (15) is provided, which in its effective position blocks the movement of the bolt (4) out of the accommodation of the built-on apparatus. The securing bolt (15) with the bolt (4) pushed out of the rapid exchange device is arranged next to its end (14) accommodated inside the rapid exchange device (1) and preferable against the end (14). The securing bolt (15) is adjustable crossways to the displacement direction of the bolt (4) in and out of its effective position. For adjustment of the securing bolt a linear motor (16) is provided. The linear motor is a hydraulic cylinder.
