Abstract

The invention relates to a descender. The invention provides a bar descender so as to solve the problem that the conventional bar descender is inconvenient to use. The descender is formed by combining a core shaft and an outer sleeve, wherein an outer sleeve rope-sliding port is formed on the outer sleeve; a rope-pressing ring is arranged on the outer sleeve; the rope-pressing ring can slide up and down under the control of hands; when the rope-pressing ring is positioned at the rope-sliding port, the winding rope on the core shaft is extruded, the friction force of the winding rope is increased and a human body stops descending; and when the rope-pressing ring moves upwards and departs from the rope-sliding port, the winding rope is not pressed, the friction force of the winding rope is reduced and the human body descends. The descender can serve as a hanging tool applied to construction, such as cleaning, decorating and the like of building outer walls, can serve as a hanging tool applied to building fire-fighting life saving, rescue or aloft life saving and work, and can also serve as special equipment applied to airborne landing of staff.
