Zusammenfassung:	The utility model discloses an adjustable triangular support for surveying and mapping engineering, which comprises a pedestal, three uniformly distributed hinge seats are fixed at the bottom end of the pedestal, a main supporting leg is hinged to each hinge seat, a sub-supporting leg is slidably mounted in the bottom end of each main supporting leg in a sleeving manner, and the sub-supporting leg extends to the lower part of the main supporting leg. One side of each main supporting leg is in threaded connection with a second locking bolt capable of pressing and locking the corresponding auxiliary supporting leg, a retracting and releasing disc is arranged between the main supporting legs, the top end of the retracting and releasing disc is rotationally connected with a rotating disc, a reel is arranged in the retracting and releasing disc, the bottom end of the rotating disc is fixedly connected with the reel, and three connecting belts are fixed to the periphery of the reel; three symmetrically-arranged out
