The invention discloses a spiral rotating shaft type local reverse circulation core drill bit. The spiral rotating shaft type local reverse circulation core drill bit at least comprises a connector, a transition element, a communication element, an inner pipe and an outer pipe. The upper end of the connector is connected with a drill rod. The middle section of the connector is connected with the outer pipe. The lower end of the connector is connected with the transition element. The hollow transition element is internally provided with the communication element. The outer portion of the lower end of the communication element is connected with the inner pipe through an inner pipe connector. The inner pipe is arranged in the outer pipe in a sleeved mode. The outer pipe is connected with a reamer and a core drill head. The spiral rotating shaft type local reverse circulation core drill bit further comprises a spiral rotating shaft. The spiral rotating shaft is installed in the hollow communication element after being supported through a pair of conical roller bearings and two bearing bases. Meanwhile, the upper end of the spiral rotating shaft is connected into the connector, the interior of the lower end of the communication element leads to the inner pipe after being in threaded connection with a one-way part base, a large thrust bearing is arranged between the transition element and the communication element, a small thrust bearing is arranged between the transition element and the spiral rotating shaft, and the 'two-pipe single-rotating' effect in the drilling process of the drill bit is achieved. According to the spiral rotating shaft type local reverse circulation core drill bit, the spiral blade and two-pipe single-rotating reverse circulation working principles are combined, and the collecting rate of drill cores is effectively improved.
