The device 70 is coupled to the clutch switch 601 of the shifting unit of the electric drive unit 50 disposed inside the upper rail 20, and is connected to the clutch unit 60 when the battery pack 81 is mounted inside the battery box 81 of the control module 80. The group 83 presses the button 64 to press the driving gear 61 downward, and the driving gear 61 meshes with the driven gear 65. When the shaft 511 of the shifting group rotates, the driving gear 61 rotates, and synchronously drives. The driven gear 65 meshed with the adjacent, and the blade rope set 40 wound around the blade 41 is driven by the electric drive assembly 50 and the clutch switching device 60 to electrically control the winding and unwinding of the curtain 10 . Referring to FIG. 1 , FIG. 3 , and FIG. 8 , when the battery pack 83 installed in the battery case 81 of the control module 80 is removed, and the electric curtain 10 is not in operation, the clutch switching device can be used. The spring 63 of the 60 pushes the driving gear 61 upwards, and the driving gear 61 is not engaged with the adjacent passive gear 65, so that the operation of the original electric curtain 10 can be changed to the manual mode, and the blade 41 rises and forms. The state or the falling state forms an unfolded state, whereby the user can effectively control the operation of the electric window covering 10 of the present invention by the operation means of the clutch switching device 60, thereby serving as a handling and unwinding operation of the manual and electric curtain 10 Provides great convenience. The second embodiment of the present invention is substantially the same as the foregoing embodiment, except that, as shown in FIG. 9, the clutch switching device 60a of the electric window covering 10 has a 4-body moving block 645a, and the moving block 645a is provided at one end. There is a diagonal push block 646a, wherein the upper end of the button 64a has a beveled side 644a at one end of the oblique push block 646a, so that the oblique push block 646a is in contact with the oblique side 644a, which can be used to press氐 and release button 64a. The electric window covering 10 is provided with a battery case 81. The battery case 81 is provided with an elongated perforation 810 for the other end of the pushing block 645a to extend through the surface of the battery case 81. When the pushing block 645a is moved to one end of the surface of the battery case 81, the inclined pushing block 646a of the pushing block 645a is pressed against the button 64a, and the bottom of the button 64a is pressed against the driving gear 61 to engage the driving gear 61 with the driven gear 65. The window covering 10 is electrically operated; when the pushing block 645a is moved to the other end, the button 64a is released, and the spring 63 abuts against the driving gear 61 so as not to be engaged with the driven gear 65 (as shown in FIGS. 10 and 11). The original electric curtain 10 can be replaced with a manual mode. It goes without saying that the manual and electrically switched curtains and their clutch switching devices of the present invention also include other connections and transformations, and are not limited to the solutions listed in the above embodiments. In general, the scope of the invention also includes other variations and alternatives that will be apparent to those skilled in the art.
