The invention relates to the technical field of satellite-borne component unlocking, and provides a method for unlocking a satellite-borne component by using an elastic heat knife unlocking device, which comprises the following steps: after a satellite is launched into an orbit and when the satellite-borne component needs to be unlocked, electrifying a lead of a heat knife of the elastic heat knife unlocking device so as to heat a knife rod of the heat knife to reach a melting point of a rope; and after the rope is fused, unlocking of the on-satellite component is realized. The elastic hot knife unlocking device used by the invention is relatively low in manufacturing cost and short in production period; the impact during unlocking is small, and the stability of the satellite in the running process is improved; the strength and the reliability are high; and the occupied volume is small, the installation is simple and convenient, and the application value is high. 本发明涉及星上部件解锁技术领域，提出一种使用弹性热刀解锁装置解锁星上部件的方法，其中在卫星发
