摘要

On the holder (32) at least one extension part (36) can be fitted by holder rails (52) parallel to the longitudinal direction of the holder. In the extension permanent magnets are inserted. The permanent magnets in the extension are so weak that the unit housing (11) held by the magnets can easily be removed from the extension. The distance between the holder and the extension is variable. USE - To securely but releasably retain several units, such as electric motors.
