description The present invention relates to a foldable projection module, comprising an emergent-end optical assembly, a light-source-end optical assembly, and an optical path folding structure arranged therebetween, wherein the emergent-end optical assembly and the light-source-end optical assembly are respectively connected and fixed to a first mounting face and a second mounting face of the optical path folding structure. The optical path folding structure comprises a shaft sleeve and a composite rotating shaft, wherein the housing of the shaft sleeve is provided with the first mounting face, and a window in the face thereof facing away the first mounting face; the composite rotating shaft is provided with a columnar portion nested into an inner cavity of the shaft sleeve and an extending portion extending outwards from the columnar portion and passing through the window, the end face of the extending portion serving as the second mounting face; and a light through hole extends through the columnar portion and the ex
