Traditional thread binding putting is walked in shaft type limited rotation in center

The utility model discloses a traditional thread binding putting is walked in shaft type limited rotation in center belongs to the antenna and walks the technical field of line mechanism. It includesthe center pillar and uses a plurality of runners of center pillar as the axle, the runner is connected with the center pillar bearing, it passes the square structure to have the relative stiffness between two adjacent runners, the relative stiffness passes the square structure including passing cubold and second rigidity biography cubold with two adjacent one of them fixed connection's of runnerfirst rigidity respectively, runner in two adjacent runners turns over a constant angle when spending, first rigidity passes the cubold and contacts and transmit the rigidity torque for another runnerwith second rigidity biography cubold, all relative stiffnesses pass square structure from the top down in proper order along the same circumferencial direction constant angle degree that staggers, still be equipped with the f
