[0051] The working principle of this specific implementation method is as follows: when window sash 2 is opened, combined with... Figure 7 As shown, when window sash 2 opens outward by 90 degrees, it opens outward. When the left end of window sash 2 contacts the self-removing shock-absorbing limiting piece 7 on the left side, window sash 2 is limited. When window sash 2 continues to open outward, combined with... Figure 8 As shown, the pulley 5 installed on the window sash 2 will slide to the right within the long track 3, combined with Figure 9 As shown, the window sash 2 opens to 170° until the right end of the window sash 2 contacts the self-removing shock-absorbing limiter 7 on the right side. At this time, the window sash 2 opens to the maximum angle, that is, the inner wide-angle opening process. At this time, the outer side of the glass on the window sash 2 reaches the safest position closest to the room. Whether it is the standardized cleaning of the outer side of the glass or the inspection and maintenance of the outer side of the window sash 2, the operation difficulty is reduced and the operation is ensured to be standardized and safe.
