Surveying and mapping geographic information engineering data acquisition device

The invention relates to the technical field of surveying and mapping, in particular to a surveying and mapping geographic information engineering data acquisition device which comprises a surveying instrument and an indium steel ruler and further comprises an adjusting supporting frame, the adjusting supporting frame comprises a universal rotating piece, a sliding block, a telescopic rod, two adjusting rods and three supporting rods, and the universal rotating piece comprises a drum-shaped shell and a universal rotating head. The sliding block and the drum-shaped shell are each provided with a locking piece, each adjusting rod comprises two first telescopic ends, and each telescopic rod comprises two second telescopic ends. The invar ruler can be driven by the two adjusting rods to perform small-amplitude universal swing among the three supporting rods by taking the universal rotating head as a fulcrum, so that the bubble is adjusted to the center, and finally the invar ruler is ensured to be in a relatively
