The guide surface coacts with widely spaced apart end portions of two guide rods, the opposite end-parts of which are placed closer together and are pivotally mounted on the bottom stand-part and coact with one or more devices which function to forcibly create a clear related rotational pattern for the two guide rods. The arrangement also includes spring devices which act between the bottom stand-part and at least one of the guide rods.
