Referring to fig. 1-4, fig. 1-3 are schematic structural diagrams of a protective case of a mobile terminal in three different states. Fig. 4 is an exploded structural view of the protective case of the mobile terminal of fig. 1. The application provides a mobile terminal protective housing, which comprises a housing 10 and a mobile terminal bracket 20.
