Model breaks when I want to make a new position?

Question

Blender

Here is my model, I loaded it with parts, made the body a parent for all parts, initially everything is fine

now I move the parts of the model, and as soon as I choose from below how many frames to make this movement, I have a part of the model teleported forward

And every time I want to put a new one position and from below I set the keys to yellow, my parts of the model diverge further and further.

Honestly, I don’t know, but I think you don’t have scales applied, and when did you bind the parent, which option did you use?
