The invention discloses a driving device based on a shape memory alloy, and belongs to the field of power devices. The device comprises the end fixing frames, amiddle stabilizing frame, the SMA springs and the heating pipes. The two ends of a power shaft provided with the middle stabilizing frame penetrate through the corresponding end fixing frames respectively, the heating pipes are installed atthe ends, opposite to the middle stabilizing frame, of the end fixing frames, and the through holes for the heating pipes to pass through are formed on the middle stabilizing frame, and the heating pipes are located in the SMA springs. According to the present invention, the SMA springs are deformed through a heating rod to provide the power, so that the pollution to the environment is small. Thedevice is simple in structure and can be used in a stacked manner. 一种基于形状记忆合金的驱动装置，属于动力装置领域。包括端部固定架、中间稳定架、SMA弹簧和加热管；安装有所述中间稳定架的动力轴两端分别穿过对应的端部固定架，端部固定架与中间稳定架相对的一端安装有加热管，中间稳定架上设有用于加热管通过的通孔，加热管位于SMA弹簧内。本发明通过加热棒使SMA弹簧形变来提供动力，对环境的
