Description

technical field [0001] The invention relates to the field of firefighting equipment, in particular to a multifunctional lifesaving device for firefighters. Background technique [0002] At present, firefighters’ lifesaving ropes are generally carried in a winding manner. When using them, they need to untie the ropes in the winding state, and perform operations such as knotting according to the required length or use method, and the operation efficiency is low; this type of rope is prone to occur between multiple ropes Knots between them will affect the use; the rope needs to be rewound after use, which is extremely inconvenient. Many inconvenient factors cause fire-fighting life-saving ropes to have a low utilization rate in disaster rescue. When running into an emergency, it is not convenient to use this type of life-saving rope to avoid danger quickly. Contents of the invention [0003] The object of the present invention is to address the above problems and provide a m...
