Abstract
A fastening structure of a rangefinder wheel includes a first unit and a second unit. The first unit includes a first base which has a first passage defined axially therethrough for receiving a first tube therein. A lever is pivotably connected to the first base and has an engaging hole. A first spring and a second spring are biased between the first base and the lever. The second unit is pivotably connected to the first base and has a second base which has a second passage defined axially therethrough for receiving a second tube therein. An engaging member is connected to the second base and has a protrusion which is engaged with the engaging hole of the lever. The lever compresses the first spring to move a distance transversely. The lever compresses the second spring to move a distance axially so as to separate the lever and the engaging member.
