The needle holder broke off.
You probably need to contact a pfaff dealer that has a sewing machine repair technican, to see if they can get the part.

your needle bar has been pushed up and is out of adjustment. You need to take off the side cover, there should be a screw on the back of your machine holding it on. Remove this screw, and remove the cover.You may have to remove the light assembly to reach the screw on the needle bar. Once you can see the needle bar, rotate the handwheel until you can see the screw on the needle bar. Loosen this screw SLIGHTLY until you can turn the needle bar. Hold and rotate the needle bar back and forth as you push down slightly. This will lower the bar.Lower it about 1/4 inch. Adjust the needles by turning the bar so that they are straight across. Tighten the needle bar screw so that the bar doesn't move. Turn the handwheel to see if the threads will be picked up. If not, adjust until they are. Tighten the needle bar screw tightly,reinstall the side cover ,and tighten the screw. Change your needles.Rethead and sew.

There are two holes running vertically inside the needle arm.........the needles are held firm by very small screws or hex allen keys.........they may have worked loose over time, if they have fallen out and been lost, it is a call to your local Pfaff dealer for advice......be sure to quote model number.
Your User manual may have a diagram to assist.
Have you ever changed the needles since buying this machine ??
Needles ought to be changed every 6 - 8 hrs of sewing, and more often with heavy or abrasive fabric.

Good luck. I found a replacement part for one of mine on Ebay. Just search for Used Juki Serger for parts. Maybe you'll find a 644D for cheap enough that you can scavenge parts for a few more years.
