The invention relates to a zoom lens module comprising a first lens set, a second lens set and a fixing device, characterized in that the fixing device comprises a first fixing rod, a second fixing rod, a third fixing rod and a rotating element; one end of the first fixing rod is fixedly connected with the first lens set, while the other end is connected to the rotating element; one end of the second fixing rod is connected with the rotating element, while the other end is fixed with the second lens set. The zoom lens module also comprises a third lens set fixed to the third fixing rod. The third fixing rod is connected to the first fixing rod through the rotating element, and together with the first fixing rod arranged at opposite two sides of the rotating element. The second fixing rod selectivley rotates around the rotating element toward the first lens set or the third lens set, so that optical axes of the second lens set and the first lens set or the third lens set are coincident to realize zooming. The zoom lens module has simple structure, does not need a plurality of transmission mechanisms, and is convenient to manufacture.
