| description | The invention relates to a lens module. The lens module is used for providing an image beam. The lens module comprises a limiting element, a first lens, a second lens and a third lens. The first lens is arranged on one side of the limiting element. The second lens is arranged on the other side of the limiting element. The second lens is positioned between the limiting element and the third lens, wherein the edges of the first lens, the limiting element, the second lens and the third lens respectively comprise at least one connecting structure, and the first lens, the limiting element, the second lens and the third lens are mutually matched by the at least one connecting structure itself to be stacked to form a lens module. The lens module can reduce the volume of the lens module and can reduce the weight of the projection device.
