To this end, a bolt 30 is provided which can be rotated by means of a tool, wherein the bolt 30 has two ring bodies 31 with a recess for the partial insertion of the side walls 22 of the bracket 11 between the rings. In this case, the bolt 30 cannot move relative to the bracket 11 in the axial direction, but the horizontal distance between the stopper 15 and the pulley 6 can be changed by the rotation of the bolt 30 because the stopper 15 is constructed with the bolt 30. internal thread.

Around the stopper 15, there is further provided a lever 35 supported by the rotation about the horizontal axis, which is formed by a T-shaped connecting piece on the guide rail 2 to form a pull-out prevention device. Set. The lever 35 has an aperture 36 through which the stopper 15 can pass, thereby realizing the function of the stopper 15 and the pull-out prevention device 35 in a compact structure.

7A to 7C show the back side of the vertical side of the mounting member 9, which is provided with a plurality of elongated holes 40 oriented obliquely with respect to the horizontal and vertical lines. Pegs 41 fixed to the bracket 11 are inserted into the three elongated holes 40. Further, a plurality of pegs 41 passing through the vertically elongated holes 42 are fixed to the stopper 15. When the distance between the stopper 15 and the pulley 6 is adjusted by the rotation of the bolt 30, the peg 41 is moved along the inclined elongated holes 40, see Figs. 7B and 7C. When the distance between the pulley 6 and the stopper 15 is increased, the mounting member 9 is settling, and when the distance is reduced, the mounting member 9 is lifted. The adjustment mechanism can adopt a construction scheme as shown in Figures 3A to 3E of DE 10 2011 050 394 A1. According to this solution, the bracket 11 and the stopper 15 are always at the same height.
