Morphology
Both constituent nouns directly describe the same object — 'coil' (a wound/helical form) and 'spring' (an elastic, often coiled, mechanical part) — so the compound simply names a spring that is in coil form. This is a fully compositional, productive noun+noun compound (and mirrored in many languages), so a B1 learner who knows both words will readily infer the meaning.
Etymology
Coil spring comes from its shape: a metal wire wrapped into a tight coil that works as a spring. When the coil is squeezed or pulled it holds energy and pushes back, so the name shows why it is used 'to absorb shock' or 'to keep things in place'.
