The invention relates to a stepwise shearing type orienting knob automatic releasing device, and belongs to the field of civil rockets. The stepwise shearing type orienting knob automatic releasing device comprises a locking screw, an orienting knob, a positioning barrel, a pull rod, a support block and a screw cover, wherein the positioning barrel is arranged on the side wall of the back end of an elastic body in a sleeving way; the pull rod is inserted into a rectangular hole in a positioning barrel boss; the orienting knob is fixed on the outer side plate surface of a locking screw connecting hole in the front end of the pull rod by welding; the locking screw passes through a stepped through hole in the center of the orienting knob in order that the front end of the locking screw is in threaded connection with a threaded hole in the side wall of the elastic body; the support block is fixed on the inner side plate surface of a support block connecting hole in the back end of the pull rod through a screw; the front end of the support block is pressed against the side wall of the elastic body in order that the pull rod is parallel to the axis of the elastic body. The stepwise shearing type orienting knob automatic releasing device is simple in structure, is convenient to assemble, and has important popularization and application values; on the premise of ensuring the original basic functions of positioning, locking and the like, an automatic releasing function during emission is realized, and the adaptability of a civil rocket is greatly enhanced.
