1. A laser-ranging telescope with switchable magnification, comprising:
a main body provided with a laser channel, and a first optical path channel and a second optical path channel arranged in parallel along an axial direction, a through-hole being provided between the first optical path channel and the second optical path channel;
a first objective lens set arranged at a first axial end of the first optical path channel;
an eyepiece set arranged at a second axial end of the first optical path channel;
a second objective lens set arranged at a first axial end of the second optical path channel with magnification different from the first objective lens set;
a reflective switching plate arranged within the first optical path channel and deflectable between a first position and a second position; and
a first reflector tilted within the second optical path channel and configured to reflect natural light entering the second optical path channel to the reflective switching plate;
wherein when the reflective switching plate is positioned in the first position, the reflective switching plate closes the through-hole, and the natural light emitted by a target object passes through the first objective lens set and enters the first optical path channel to form an image at the eyepiece lens set; and
wherein when the reflective switching plate is positioned in the second position, the first optical path channel communicates the second optical path channel, and the natural light emitted by the target object passes through the second objective lens set and enters the second optical path channel, is reflected to the reflective switching plate by the first reflector, and is then reflected by the reflective switching plate to be imaged at the eyepiece set.
