Parenting immovable object to animated armature

Hello,
I’ve been following your tutorials in blender and I was wondering if it would be possible to get your assistance about something that I’m designing.
I’m recreating a scene from this youtube video. https://www.youtube.com/watch?v=htYVs1XZ5UM but I was having some difficulty parenting the hand bone to the pole. In the comments the creator says, parented two locators to the pole and then parent constrained the hands to the locators

I wasn’t entirely clear what he means.

Every time I parent to the bone the pole moves with the character that I downloaded from plask.

Would you be willing to help? I would be happy to send you the blender file if you would be interested in looking at it.
