Handcuffs tattoo means bondage and loss of freedom. Handcuffs are the most commonly used police tools. Their structure is familiar to everyone. They are generally divided into connecting chain and plate handcuffs. Today, plate handcuffs are more commonly used.
Plate handcuffs and chain handcuffs are two common forms of handcuffs. The difference mainly lies in the connection of handcuffs and rings. The chain cuff is an earlier design. The cuff rings are connected in series with 2 to 3 iron rings. Although this design binds people’s hands, the moving radius composed of the length of the chain is still quite long, and the action of the handcuffed person is still very convenient.
