Of course, a stepper motor can also be used as the annular travel driver 613.

When taking the longitudinal reinforcement, the two annular walking mechanisms 610 drive the two longitudinal reinforcement material taking fixtures 631 to move to the longitudinal reinforcement material taking station by themselves, and the longitudinal reinforcement material taking jacking device 620 drives the longitudinal reinforcement material taking fixture 631 to the longitudinal reinforcement placement area, and the two longitudinal reinforcement material taking fixtures 631 respectively clamp the corresponding ends of the longitudinal reinforcement, and then the two annular walking mechanisms 610 drive the two longitudinal reinforcement material taking fixtures 631 to move to the corresponding longitudinal reinforcement binding area by themselves, and then the longitudinal reinforcement material taking jacking device 620 continues to push the longitudinal reinforcement material taking fixture 631, so as to send the longitudinal reinforcement to the corresponding binding station.
