Zusammenfassung:	The utility model discloses a demonstrating teaching aid for force bearing and deformation of a lock bolt bearing pretightening force and working pulling force, which comprises a combined bolt and an elastic compressed member combined structure. The combined bolt comprises an upper fixing end, a lower fixing end and a deforming member which is arranged therebetween. The elastic compressed member combined structure comprises a pad, an elastic compressed member and a nut backing plate which are successively stacked. The demonstrating teaching aid provided by the utility model can visually demonstrate force bearing and deformation of a bolt and a member which is connected by the bolt, wherein the bolt bears the pretightening force and the working pulling force.
