Claim:
A zoom lens structure comprising: a diaphragm member; a fixed lens barrel having a front lens barrel end and a rear lens barrel end, and the front lens barrel end having at least two first guide slots and a diaphragm aperture, and the diaphragm aperture for fastening the diaphragm member, and the rear lens barrel end having at least two second guide slots; a front track lens barrel having a barrel body, a driven gear and a rear end ring, and the barrel body having at least two first tracks, and the rear end ring having a zooming fixed screw hole, wherein, by using the driven gear connected to the barrel body and the rear end ring, a diaphragm slot is formed and permits displacement of the diaphragm member in the diaphragm slot; a driving motor assembly having a driving motor and a gear wheel, wherein the front track lens barrel rotates through the gear wheel combined to the driving motor driving the driven gear; a rear track lens barrel having at least two second tracks and at least two fixed screw holes, and at least two screw bolts for locking the front track lens barrel and the rear track lens barrel through the zooming fixed screw hole and the fixed screw hole so that the front track lens barrel and the rear track lens barrel can move simultaneously; a front lens barrel module having a front lens barrel, at least two first guide screw cylinders and a front lens group, and installed inside the front lens barrel end of the fixed lens barrel, wherein the front lens group is moved through the first guide screw cylinder locked to the front lens barrel and the displacement of the first guide screw cylinder within the first guide slot and the first track; and a rear lens barrel module having a rear lens barrel, at least two second guide screw cylinders and a rear lens group, and installed inside the rear lens barrel end of the fixed lens barrel, wherein the rear lens group is moved through the second guide screw cylinder locked to the rear lens barrel and the displacement of the second guide screw cylinder within the second guide slot and the second track and thus moves the rear lens group.
