If you don't want to use a plier, you can wear a good pair of gloves and push with your thumb. I found the spring can dig into your bare finger causing some discomfort. Sometimes it does get stuck so I use pliers and I haven't broken any with pliers yet.
If your main concern is the head tilt, you can stuff cotton balls between the spring loop on one side to adjust the head tilt. I've been using really strong magnets to artificially bring the spring loop close together and get the head tilt angel how I like it for the display. This has the added benefit of making the head "magnetized" so things stick to the pop's head which works well for Dr. Doom or Magneto.
