The invention discloses a buffer regulating technique based extractor control system. The buffer regulating technique based extractor control system comprises a support regulating mechanism distributed at the bottom of an extractor and is characterized in that the support regulating mechanism comprises six second buffer bases distributed circumferentially, a first buffer base is installed in the center of the second buffer bases and is connected with the same through fastening strips, and the first buffer base and the second buffer bases are identical in structure. By the arrangement that the six second buffer bases distributed circumferentially and the first buffer base located in the center of the second buffer bases, the base of the extractor can be well buffered and supported, impact force on the vertical direction can be effectively decomposed under mating reaction of pistons and piston barrels, good using effect is achieved, service life of the extractor is greatly prolonged as well, and steady and continuous running of the extractor in system is guaranteed.
