Disclosed is a rod-type lowering device formed of a core axle (1) and an outer sleeve (2). An outer sleeve sliding rope hole (2.3) is provided on the outer sleeve, and a rope pressure ring (2.4) is also provided on the outer sleeve. The rope pressure ring can slide up or down under the manual control of a person and when the rope pressure ring is located at the position of the sliding rope hole, a wound rope (3.2) on the core axle is squeezed, the frictional force on the wound rope becomes greater, and a person (4) will stop being lowered. When the rope pressure ring moves upwards away from the position of the sliding rope hole below, the wound rope is no longer compressed, the frictional force on the wound rope lessens and the person will be lowered. The lowering device solves the problem of current rod-type lowering devices being inconvenient to use. Not only can the lowering device serve as a suspension tool during work such as cleaning or fitting the outer walls of a building, but the device can also serve as a suspension tool during tasks such as fire-fighting and rescue from buildings, emergency response or high altitude rescue, and serve as specialized equipment for airborne landing of personnel.
