TECHNICAL FIELD
[0001] The utility model belongs to the technical field of restraint device, specifically relates to a lower limb restraint device. BACKGROUND
[0002] In the law enforcement process according to specific circumstances, the behavior ability of suspect may need to be controlled, and common restraint police instruments include handcuffs, leg shackles, headgear and the like. Among them, the leg shackles are mainly used for serious violent criminals with high risk, criminals with risk of escape, special criminals in custody and escort, and the like. The existing leg shackles can be divided into heavy shackles and light shackles, and the criminals in custody mainly use light shackles.
[0003] In addition to the above criminal groups, in the actual case handling process, the leg shackles are also applied to the suspects with danger. The existing leg shackles are mainly made of metal materials, which can cause a certain degree of harm to the suspects, and the metal leg shackles carried by the case handling police can affect the action ability and are inconvenient to carry. In addition, not all suspects meet the legal conditions of shackling, but the action ability of the lower limbs needs to be limited, and therefore, there is a lack of a light, strong and harmless instrument for limiting the action ability of the lower limbs.
