ABSTRACT:
The present invention relates to a controlling shaft, and more particularly to a controlling shaft for controlling blind, comprising a transverse shaft and a plurality of shaft controlling unit provided on the transverse shaft in turn. Due to the connecting relationship between the plurality of shaft controlling units and the transverse shaft, when the transverse shaft rotates, the plurality of shaft controlling units can synchronously rotate with the transverse shaft. Each shaft controlling unit of the plurality of shaft controlling units comprises a plurality of rotating members. When the shaft controlling unit rotates with the transverse shaft, the rotating members of each shaft controlling unit move in different pace. With the synchronous movement of the shaft controlling units with the transverse shaft, the particular points on the outer side of respective plurality of rotating members of any shaft controlling unit at the same level move to different extents.
