Morphology
The meaning is directly and predictably built from the constituents: 'action' (the moving part that makes a device operate) + 'mechanism' (assembled moving parts), so a learner who knows both words can infer this refers to the mechanical part that produces or transmits action. This noun–noun compositional pattern is common in English and cross-linguistically, making the phrase immediately comprehensible to a B1 learner with knowledge of the constituents.
Etymology
Action mechanism comes from two simple ideas: action (a movement) and mechanism (the parts inside a machine). Imagine a piano key that moves tiny parts to hit a string — those parts are the action mechanism, the pieces that make movement happen, so the term means 'the machine parts that pass on power and start movement'.
