Normal map stretching on my models

I have been trying to bake a normal map in blender but each time i bake the map with or without using a cage i get really bad stretching on the final result.

Does anyone have a solution to my problem?

Can you share your blend file maybe?

For better comprehension of the case, we need the .blend file.
ps: If you put the .blend, do not forget to “pack files.”
