A zoom sighting telescope. During use, an outer tube is rotated, a sliding pin is limited by a zoom curve slot and a sliding pin sliding slot, and the sliding pin drives a directable lens frame inner tube to slide in the axial direction, thereby controlling and adjusting the distance between two directable lens frames, performing zoom adjustment on the sighting telescope, and ensuring that the sliding pin is always located at the top of the device during the sliding process. The directable lens frames and the inner tube are connected by means of a spline, so that the directable lens frames slide along the axial direction in the inner tube, thus being able to effectively prevent rotation from occurring between the directable lens frames and the inner tube, ensuring the adjustment precision of the sighting telescope. A fixing tube is used to connect an outer tube, preventing radial deformation of the zoom lens, and a plurality of fixing points are provided, the fixing sleeve and the outer tube being fixedly connected at a position close to the zoom curve slot in order to reduce deformation in the zoom curve slot, and thereby reduce the possibility of deformation of the sighting telescope during use.
