There is also a new type of handcuffs that is widely used at present. It was invented and used since the 1980s. Most of them have added anti-pickers, and the lock cylinder is generally a special-shaped column, and a special key must be used to turn the lock cylinder to open the handcuffs.

Even so, this novel handcuffs still has the following two defects: the one, because this handcuffs can only be opened with a key, problems such as key loss and key keeping confusion often occur when police officers use it, which is very impractical; It is due to the simple structure and principle of the handcuffs. Although the anti-pick is added, as long as there is a hard object and a little understanding of the principle, the handcuffs can still be easily opened by using ordinary hard objects to remove the anti-pick from the snap ring.

[0003] The overall structure of the handcuffs used by the police in developed countries is not much different from that in China, but in terms of specific structural form and appearance design, in comparison, the handcuffs commonly used by police in our country still have the following deficiencies in terms of shape and structural design: ① There are no positioning grooves on both sides of the handcuff ring, which is not easy to occlude and locate. The gap is large, unstable, and the actual operation is inconvenient. And the operation is more complicated, especially after the handcuffs are completed, it is more difficult to complete the lock, which poses a safety hazard for law enforcement; ③The distance between the two handcuff rings is large, and the criminals can easily change from back handcuffs to front handcuffs; Inconvenient to carry, the design of the handcuffs is bulky, without considering the psychological feelings of the arrested prisoner in the public
