Which term describes the component that actuates the lock in a handcuff?

• A. Push-pin double lock
• B. Key actuator
• C. Lock housing mechanism
• D. Double Strand

Answer: (B)

Actuating the lock relies on the key actuator, the part that interacts with the handcuff key and translates turning motion into unlocking action. When the key engages this component, it moves the internal locking bolt or pawl, releasing the cuff so it can open. The push-pin double lock is a separate feature used to set a secondary locked state that prevents tightening, not the part that unlocks. The lock housing mechanism describes the overall locking assembly, and double strand refers to the construction, not the unlocking action.
