Beschreibung
Zusammenfassung:	The invention provides an SMA material-based drive device. The SMA material-based drive device comprises an SMA coil spring, a spindle and a chassis; one end of the SMA coil spring is connected with the spindle; the other end of the SMA coil spring is connected with a bottom board; the spindle is arranged on the upper side of the bottom board. The SMA material-based drive device further comprises a first shaft sleeve and a screw; the SMA coil spring is connected with the spindle through the first shaft sleeve; a cutting groove is formed in one end of the first shaft sleeve; a threaded hole is formed in the other end of the first shaft sleeve; one end of the SMA coil spring is embedded into the cutting groove; the first shaft sleeve is screwed into the threaded hole through the screw to be connected with the spindle. The SMA material-based drive device further comprises an SMA coil spring limit ring arranged on the outer side of the SMA coil spring, and the two ends of the SMA coil spring limit ring are connected with the chassis. The SMA material-based drive device is novel and simple in structure, and has the advantages of being light in weight and good in assembly manufacturability compared with output mechanisms like a motor.
