Abstract: A sight adjusting mechanism includes an adjusting knob, an adjusting ring member, an adjusting bolt and a base. An upper-side portion of the adjusting bolt enters a through hole of the adjusting ring member to couple with the adjusting ring member. A lower-side portion of the adjusting bolt enters a through hole of the base to couple with the base. Thus, the adjusting bolt can only move along an axis. The mechanism is implemented without mechanical feedback, and thus rotating angles are improved with great precision. Also, the mechanism includes a limiting member disposed in a penetrating hole of the adjusting knob and a positioning ring mounted on the adjusting ring member. By cooperation of the limiting member and the positioning ring, an angle at which the adjusting knob can rotate is defined. A fine adjustment and a quick adjustment of a sight point are implemented.
