1. An optical imaging lens assembly, comprising nine lenses, from an object side to an image side, the nine lenses are sequentially:
a first lens with positive refractive power,
a second lens with positive refractive power, of which an object-side surface thereof is a convex surface while an image-side surface is a concave surface,
a third lens with refractive power, of which an object-side surface thereof is a convex surface while an image-side surface is a concave surface,
a fourth lens with refractive power,
a fifth lens with refractive power,
a sixth lens with refractive power,
a seventh lens with positive refractive power,
an eighth lens with refractive power, and
a ninth lens with negative refractive power, of which an object-side surface thereof is a concave surface while an image-side surface is a concave surface; and
the nine lenses are independent of one another and have air spaces on an optical axis;
SAG61 is an on-axis distance from an intersection point of an object-side surface of the sixth lens and the optical axis to an effective radius vertex of the object-side surface of the sixth lens, SAG62 is an on-axis distance from an intersection point of an image-side surface of the sixth lens and the optical axis to an effective radius vertex of the image-side surface of the sixth lens, SAG61 and SAG62 meet 1.4<SAG61/SAG62<2.4.
