As a judicial tool, handcuffs are designed and applied in a way that balances the dual needs of law enforcement efficiency and human rights protection. Modern societies governed by the rule of law require that their use be strictly regulated by law, and that the risk of abuse be reduced through technological improvements and standardized training.
The True Meaning of "Double Locks"
Anti-Tightening
This is the most important function. After the double locks are engaged, the ratchet mechanism of the handcuffs is locked. Even under strong pressure or impact, the handcuffs cannot tighten further automatically, preventing accidental injury to the person being handcuffed (such as when the wrist is swollen).
Anti-Pry Lock
The added locking mechanism makes traditional simple unlocking tools such as thin wires and paperclips ineffective, greatly improving security. To open double-lock handcuffs, it is usually necessary to first rotate the key slightly in the opposite direction to disengage the second lock before normal unlocking can proceed.
