However, this technology adopts an anti-sway block to slide and press against the inner side of the window sash. The rigid contact between the anti-sway block and the inner side of the window sash reduces the swaying of the window sash. The friction caused by the swaying during long-term use can easily cause the wear of the anti-sway block and weaken the anti-sway effect. In addition, the window sash gap adjustment of this technology is set on the main body of the inclined rod, which is difficult to adjust in daily use. Therefore, this technology still has a certain room for modification. Summary of the invention
