This is a dependency node designed to take two transforms and keep a fixed distance between them. With one being the target, it will pull or push the constrained transform to maintain that distance. This node does not provide any orientation, only position constraining.
This will have several applications but works as nice way to get the affect of a car pulling a trailer or a wagon.
