Referring to fig. 5 and 6, when power is off or the window needs to be driven manually, the bolt 35 (which can be driven by a tool) is rotated to penetrate into the bolt hole 17, so that the moving block 34 moves away from the bolt hole 17, due to the arrangement of the inner inclined surface 342 of the moving block 34, the gear shaft 31 can be pushed towards the second cover plate 12 (the gear shaft 31 moves linearly along the axis of the gear shaft) until the second gear 33 of the clutch mechanism 3 is disconnected from the transmission mechanism 4 (the gear at the foremost end of the transmission mechanism 4 is disconnected), the moving block 34 is located at the second position, the clutch mechanism 3 is kept in an "off" state, the output end of the driving mechanism 2 is disconnected from the transmission mechanism 4, and the window can be pushed manually. Due to the force between the bolt 35 and the bolt hole 17, when the bolt 35 is inserted into a desired position (i.e. the gear shaft 31 is moved to disconnect the second gear 33 of the clutch mechanism 3 from the transmission mechanism 4), the bolt 35 can be kept at the position without applying an external force, so that the state of manually operating the clutch mechanism 3 does not need to be kept at all times, and the manual operation of the window is facilitated. In the above process, the first return spring 36 and the second return spring 37 are both compressed, and when the window needs to be electrically driven again, the bolt 35 is rotated in the direction out of the bolt hole 17, the moving block 34 is moved and returned in the direction of the bolt 35 by the first return spring 36, and the gear shaft 31 is moved and returned in the direction of the first accommodating space 15 by the second return spring 37, so that the second gear 33 of the clutch mechanism 3 is connected with the transmission mechanism 4 again.
