Patent attributes
A rotational sighting apparatus includes a base, an aiming member and a pressing pivotal axle. The base includes a main body, a side cover and a through hole formed on the side cover. The side cover further includes a locking portion adjacent to the through hole. The aiming member includes a rotating portion and a pivotal attachment hole formed to penetrate through the rotating portion. The pressing pivotal axle penetrates through the pivotal attachment hole to connect with the rotating portion via the through hole. The pressing pivotal axle includes a locking key moveably locked onto the locking portion and an elastic element configured to drive the pressing pivotal axle to rotate. Accordingly, when the locking key disengages from the locking portion, the elastic element drives the pressing pivotal axle to allow the aiming element to rotate from a first position to a second position.
