The invention discloses a lifesaving necklace which is mainly used for ensuring the safety during going outing and travel. The lifesaving necklace comprises an inner container, an outer ring, a switch device, and an inner object, wherein the switch device is arranged on the inner container; the outer ring wraps outside the inner container; the inner objected is arranged in the inner container when the switch device is not switched on; when the switch device is switched on, the inner object reacts to enter the space between the inner container and the outer ring. When the switched device is not switched on, the lifesaving necklace is small in size, and convenient to carry and can be worn on the neck conveniently; when the switch device is switched on, the outer ring is subjected to air inflation to enable the volume to be expanded, so that the expanded outer ring can be used as the lifesaving necklace, and furthermore the emergency lifesaving aim is realized.
