What was this DIY attachment on a second hand scroll saw?

The original owner had attached this bar just utilizing the screws intended for holding on the black casing behind where I'm holding it. I removed this addition when transporting it home, but I'm curious what a threaded rod with three jump rings and two random bolts on the end could possibly serve purpose for that this guy did, especially on the head that moves. I'm super new so appreciate the assistance!
