In history, what are the restrictions on the use of scorpions and clips?

Because the use of clamp and pliers was cruel, the use of these two interrogation instruments was limited in the Qing Dynasty. In the seventeenth year of Shunzhi (1660), the imperial court issued a letter, and anyone who asked about the punishment of the yamen had no real evidence of the stolen goods, and the family marriage was trivial, so it was not allowed to abuse the pliers. In the imperial edict of the fourth year of Kangxi (1665), when trying major cases such as robbery, theft and human life, the prisoner confessed in other yamen and later changed his mind, or the prisoner insisted on not telling the truth when there was conclusive evidence. In this case, a clip can be used; In other minor cases, if the interrogators abuse sticks, they shall be investigated and punished for the crime of intentionally violating laws and regulations. In the ninth year of Tang Dynasty (1670), another imperial edict was issued. All officials are forbidden to use other kinds of non-punishment except slapping and clamping sticks when interrogating prisoners, using clamping sticks for women and not using fingers easily for pregnant women. Offenders will be demoted or fined. Compared with the previous generation, these regulations in the Qing Dynasty were a little looser, but the two kinds of punishment, the two kinds of instruments of torture, and the two kinds of instruments of torture, were not abolished, and they were still used from time to time until modern times, which shows that the influence of these two kinds of punishments is far-reaching.
