Further, when the driven shaft 114 rotates, it can drive another driving sprocket 104 to rotate through the matching of the first spline and the second spline 128, thereby realizing the simultaneous rotation of two driving sprockets 104 through the operation of one driver 110. Furthermore, the two drivers 110 located at both ends of the rotating shaft 102 can also be controlled to operate simultaneously to realize the driving of the driving sprocket 104, which can effectively increase the driving force of the driving device 100.
