Handcuff with Automatic Over-Tightening-Prevention Mechanism
The proposed handcuff in the invention employs an innovative locking mechanism, which stops further tightening of the handcuff when the force applied on the wrist of hand or ankle of foot is greater than 1.5 lbs (or any preset value), and prevents physical injuries from over-tightening without compromising the restrain. The handcuff is 50% faster in restraining by automatically locking instead of manually push-to-locking. The handcuff has the same shape/size/cost of the handcuffs currently used by police officer, and is compatible with current training procedure or SOP.
