The invention relates to the technical field of springs, in particular to a rigidity-adjustable spiral spring and a rigidity adjusting method. The device comprises a spiral spring, and a spiral spring wire of the spiral spring is of a hollow core structure. The conductive fluid is arranged in the hollow core structure of the spiral spring, and the viscosity of the conductive fluid can be changed directly or under the action of a magnetic field after the conductive fluid is electrified; the first electrode is arranged at one end of the spiral spring; the second electrode is arranged at the other end of the spiral spring; and the electric control device is electrically connected with the first electrode, the conductive fluid and the second electrode to form a loop and is used for regulating and controlling the current in the loop. According to the rigidity adjusting method, a spiral spring device is adopted, the spiral spring device is suitable for being installed on a shock absorber of a vehicle suspension, and the control and driving comfort of a driving vehicle under different road conditions is improved by adjusting the rigidity of a spiral spring.
