The geothermal exploration drill bit with the sample collecting capacity comprises a positioning seat, a top seat, an auxiliary rod, a threaded rod and a drill bit body, positioning rods are symmetrically arranged on the outer surface of the bottom end of the positioning seat, and the top seat is arranged on one side of the outer surface of the top end of the positioning seat in parallel. Auxiliary rods and threaded rods are longitudinally arranged between the edges of the two sides of the bottom end of the top base and the edges of the two sides of the top end of the positioning base correspondingly. According to the geothermal exploration drill bit with the sample collecting capacity, rotating discs and abutting sliding blocks are arranged, when the geothermal exploration drill bit is used as a whole, the rotating discs at different layers are driven to rotate through rotation of rotating rods, meanwhile, arc-shaped limiting grooves, limiting blocks and limiting rods are arranged in a matched mode, and ther
