I had the same problem for a while, but here is what you do:

1. Make sure you have no tools when your looking at the dustpan

2. click (with no tools) the biggest thing in there, which is the spring, it will zoom in
on the spring.

3. Use tweezers to pick it up :)

There you go. Hope it helped.

i am so glad i finally just looked this up, this has been driving me crazy for HOURS. lol
sick with nothing else to do, yay video games.
