The applicant describes the working process of the present invention with reference to fig. 1 to 8, the present invention relates to an electrically and manually controlled hollow blind having two working modes in the using process, when adopting the manual operation mode, the manual and automatic switching button 321 on the control box 32 is touched and pressed by the operator, so that the blind is switched to the manual mode, at this time, the electromagnetic clutch 51 in the electric and manual switching device 5 is disconnected and closed because of power loss, the connection between the motor 31 and the left end of the rotating shaft 41 is disconnected, and the power loss electromagnetic clutch 52 is closed because of power loss, the connection between the rotating shaft driving gear seat 61 and the right end of the rotating shaft 41 is established. In the manual operation mode, the operator pulls the outer manipulator 66, because the outer manipulator 66 is magnetically attracted with the inner manipulator 63 through the inner glass 7, the outer manipulator 66 drives the inner manipulator 63 to move up and down, the inner manipulator 63 drives the traction toothed belt 62, the traction toothed belt 62 drives the rotating shaft driving gear seat 61, the rotating shaft driving gear seat 61 drives the rotating shaft 41 to rotate by a required angle, the rotating shaft 41 drives the winder 42 and the integral turning wheel 44 to rotate by an angle correspondingly, and the turning wheel 44 drives the curtain turning ladder rope 23 to turn by an angle, so that the curtain 21 turns by a corresponding angle. The up or down direction of the outer manipulator 66 determines the direction of the inversion of the curtain sheet 21, such as inward or outward inversion (also referred to as "down inversion or up inversion").
