Why are the handcuffs so bright?

Mainly because it is made of metal. It should be said that the development of handcuffs in China appeared in the late Qing Dynasty, with the development of various invading forces in China, with the appearance of concessions and with the progress of society.

Before this, there were handcuffs in China, but it was not recognized by the society at that time and was not widely used.

According to the data, there were two wooden strips tied with fingers in the Shang Dynasty, and there were copper rings in the tombs of Chu and Han Dynasties, which were the earliest metal products used for handcuffs. But because the material is copper, it can't be widely used, and it can only be used by criminals. Iron handcuffs existed in Song Dynasty, but they were not widely used in China, and they were used for the longest time before the late Qing Dynasty in China.

At the end of the Qing Dynasty, with the knocking of the gate of China, the police first appeared in the concession, and handcuffs appeared at the same time. At this time handcuffs were mainly imported from abroad. Handcuffs should be horseshoe-shaped handcuffs, which are now collected in Shanghai Public Security Museum. So handcuffs produced by foreigners appeared in China, mainly used in concessions. With the social progress in the late Qing Dynasty, police appeared in China, equipped with handcuffs. At this time, handcuffs are basically the same as those used in western society.

After the Republic of China, domestic handcuffs changed little in the early stage. There are handcuffs on the boat, too. 1937 After Japan invaded China, handcuffs made in Japan appeared in China. At this time, handcuffs were mainly used in concentration camps or prisons where political prisoners were held in China. See the Japanese concentration camp in Lushun. With the participation of the United States in the political vortex of China, American handcuffs or American-made handcuffs appeared in China and were exported.

Handcuffs appeared in the Republic of China, and at the same time, homemade handcuffs appeared in China, mainly made by warlords and some landlords and big capitalists. Manufacturing is relatively rough and simple.

After the founding of New China, the development of handcuffs was not valued at first. Some police stations use old handcuffs left by police stations during the Republic of China. Then there are clay handcuffs and copper handcuffs with locks. At this time, the copper handcuffs are plate handcuffs. With the development of police in China, the outbreak of the Cultural Revolution disturbed the normal social development. During the Cultural Revolution, handcuffs were not controlled by the state, but there were also local handcuffs. At this time, the punishment for prisoners can be said to be the least.

After the Cultural Revolution, the public security work was gradually standardized, and the state appointed military experts to start producing handcuffs. At this time, the handcuffs look very different. First of all, there are no standards and specifications in production. Second, there are many production areas. Third, public security prisons pursue different things in production and want to distinguish them. In the 1990s, handcuffs were unified and standardized by the state, forming a situation that handcuffs were mainly cylindrical handcuffs. Wooden handcuffs coexist with other handcuffs.

Before 2003, in China's public security thought, the suspect was the criminal's thought, so handcuffs appeared as instruments of torture in many cases, and the state did not regulate their use. First, there are many handcuffs with the color of torture devices, which are aggravated. Second, many methods of handcuffing are not standardized, such as handcuffing up and down, which leads to the disability of some prisoners.

In recent years, the development of handcrafting in China has been relatively rapid, and its scope of application is also relatively large. These handcuffs are widely used by international peacekeeping forces in China and are also famous in the world. Second, some people in China began to study handcuffs and apply for patents as products of the public security system.

The use of handcuffs in the public security system has some international influence at home, and the people use handcuffs for other purposes, which represents the use of * *.

To sum up, the development of handcuffs is also a microcosm of the development of police history in China, a reflection of the strength of the country and the embodiment of national laws. Nowadays, with the development of people-oriented thought, the respect for prisoners' personality and the regulation of handcuffs' right to use are also from heavy to light, which is safe, comfortable and beautiful.
