When the window cover 2 needs to be opened, the operator pushes the lock rod bent foot 411 upward to make the lock rod 41 pull the lock head 421 out of the cooperation with the lock hole 132 by overcoming the elastic force of the reset spring 422, at this time, the window cover 2 is rotated to open around the hinge shaft 7 under the action of the torsional spring 6, and generally, the torsional force of the torsional spring 6 can make the window cover 2 open by 30° to reach the pre-opening state, the support plate 3 is pushed forward by the window cover sliding shaft 22 to rotate around the support plate hinge shaft 12, the window cover sliding shaft 22 slides along the opening guide groove 322 until it slides into the pre-opening positioning groove 323, at this time, if the window cover 2 needs to be continuously opened, the window cover sliding shaft 22 needs to slide along the opening guide groove 324 by overcoming the gravity of the support plate 3, and the torsional force of the torsional spring 6 is insufficient to overcome the gravity of the support plate 3, so in the pre-opening state, the window cover 2 can be kept in the pre-opening state under the double action of the torsional force of the torsional spring 6 and the gravity of the support plate 3; when the window cover 2 needs to be completely opened, the operator pulls the handle 23 to make the window cover 2 continuously rotate to open around the hinge shaft 7, at this time, the window cover sliding shaft 22 slides along the opening guide groove 324 by overcoming the gravity of the support plate 3 until the window cover sliding shaft 22 falls into the opening positioning groove 325, the support plate 3 supports the window cover 2 through the opening positioning groove 325 to make the window cover 2 keep in the completely opened state; when the window cover 2 needs to be closed again, the operator lifts the connecting rod 31 to make the window cover sliding shaft 22 out of the opening positioning groove 325, and then the operator pushes the window cover 2 to close to the state that the lock head 421 is inserted into the lock hole 132. When the torsional spring 6 is used for a long time to reduce the torsional force or the torsional spring 6 used has too large torsional force, the torsional force stability of the torsional spring 6 can be kept for a long time by adjusting the cooperation between the torsional spring adjusting part 61 and the adjusting groove 51 at different positions on the adjusting disc 5, which greatly prolongs the service life of the shutter structure.

[0034] It should be noted that the above embodiments can be freely combined as needed.
