The utility model relates to the technical field of anchoring and supporting, in particular to a spring anchor cable and an anchoring device. A cable body of the spring anchor cable is provided with at least one spiral elastic section formed by winding a whole bundle of the cable body in the length direction of the cable body, and a core body is arranged on the inner ring of the spiral elastic section and distributed in the length direction of the spiral elastic section in a penetrating mode. The whole cable body is of an integrated structure and is high in structural strength and good in stability. Moreover, by arranging the spiral elastic section, vibration energy generated under the action of instantaneous impact loads such as earthquakes and rockburst can be absorbed, the cable body isprevented from being overloaded or snapped, and good extension performance can be shown under the condition of large deformation of engineering, so that the required supporting resistance is guaranteed.
