1. An optical lens module, comprising:
a first lens barrel;
a first lens assembly, fixed in the first lens barrel, wherein the first lens assembly has a first optical axis and comprises at least one lens element;
an optical folding element;
a second lens barrel; and
a second lens assembly, fixed in the second lens barrel, wherein the second lens assembly has a second optical axis and comprises at least one lens element, and all optical elements of the second lens assembly have no relative movement with respect to each other;
wherein a light ray sequentially passes through the first lens assembly, the optical folding element and the second lens assembly;
wherein the optical folding element has a reflection surface, such that the light ray is reflected into the second lens assembly after passing through the first lens assembly, and the first optical axis and the second optical axis intersect on the reflection surface;
wherein the optical folding element is fixed to each of the first lens barrel and the second lens barrel, with no direct contact between the first lens barrel and the second lens barrel;
wherein an angle between the first optical axis and the second optical axis is 0, and the following condition is satisfied:
70 [deg]≤θ≤110 [deg].
