The invention discloses an expansion mechanism for a movable and extendable shelter. The expansion mechanism comprises a shelter body and is characterized in that the shelter body is wholly in a cuboid shape; the left side and the right side of the shelter body are provided with expansion bins, the bottoms of the expansion bins are provided with expansion mechanism bodies, and the expansion mechanism bodies drive the expansion bins to move in the left-and-right direction of the shelter body so as to enable the expansion bins to extend out or draw back; and the expansion bins on the left and right sides are flushed with the left side and the right side of the shelter body when drawing back. By means of the expansion mechanism for the movable and extendable shelter, the width of the shelter can be expanded conveniently, the internal space of the shelter is increased, various movement requirements are met, the functionality of the shelter is improved, the expansion bins can be drawn back conveniently, fast and easily when the shelter needs to be transported so that the width of the shelter can meet the standard width of a transport vehicle, the safety, feasibility and convenience of transport are guaranteed, and the maneuvering characteristic is high.
