Surveying and mapping tripod capable of controlling folding and unfolding through interlocking cooperation

The invention relates to a surveying and mapping instrument technology, in particular to a surveying and mapping tripod capable of controlling folding and unfolding through interlocking cooperation, which comprises a cradle head and three groups of bracket assemblies, the bracket assemblies are distributed below the cradle head at equal intervals along the circumference, one end of each bracket assembly is rotatably matched with a rotating shaft, and the rotating shaft is rotatably arranged below the cradle head; the other end of the support assembly is provided with a moving wheel set. And a retracting and adjusting mechanism is arranged in the center of the lower part of the holder and is matched with the bracket assembly and the moving wheel group respectively. According to the surveying and mapping tripod disclosed by the invention, through a mechanical matching interlocking mode, the length of the bracket is shortened along with the reduction of the unfolding angle of the bracket when the tripod is folde
