The knuckle thrower is a small, internal component located inside the body of a railway coupler.
Its function is to act as a lever; when pushed by the release mechanism, it applies force to the knuckle, causing it to rotate into the open position.
To withstand repeated impact, it is commonly manufactured through forging or precision casting to achieve high strength and wear resistance.
