The invention provides a torsion spring stress loader and a torsion spring stress loading method. Two disc bodies are arranged on a center rod at intervals, at least one disc body is in threaded fit with the center rod, limiting rods are fixedly arranged on the two disc bodies respectively, and the portion, between the two disc bodies, of the center rod is used for being sleeved with a torsion spring. The method comprises the following steps: taking down an upper disc body and a matched nut; a torsion spring needing to be loaded is arranged on the center rod in a sleeving mode, it is ensured that the two claw parts of the torsion spring abut against the limiting rods respectively, and then the upper disc body and the nut matched with the upper disc body are installed on the center rod again; the upper disc body is rotated, when the included angle between the two claw parts of the torsional spring reaches a preset angle, the upper disc body is kept still, and then a nut matched with the upper disc body is scre
