How to make copy of object with 1,1,1 scale?

I want to stickman with IK (Inverse Kinematics), and I have problem. For rotating children objects correctly, parent and children object needs to be 1, 1, 1 scale. And I need to copy objects with 1,1,1 scale without changing its form. Without this I have something like this:

Just seperate your bone hierarchy from your actual visual objects. Keep the empty bone gameobjects as the scale (1,1,1). Add your visual objects as children of the bones. You can scale your visual objects as you like, just do not put any other children under those objects.
