When the window sash is closed, the first mounting seat 1 on the window frame is fixed, and the second mounting seat 2 rotates by taking the second pin shaft 41 on the second linkage rod 4 as an axis. Because the sliding pin 31 on the first linkage rod 3 is slidably connected with the second kidney-shaped hole 21 on the second mounting seat 2, when the second mounting seat 2 rotates, the first linkage rod 3 is driven to rotate by taking the screw shaft 332 on the eccentric adjusting bolt 33 as an axis, and meanwhile, the sliding pin 31 slides along the second kidney-shaped hole 21. Because the first linkage rod 3 is hinged to the second linkage rod 4 at the middle position, and the end of the second linkage rod 4 is hinged to the first pin 133 on the tightness adjusting device, when the first linkage rod 3 rotates towards the first mounting seat 1, the second linkage rod 4 is driven to rotate towards the first mounting seat 1, and meanwhile, the tightness adjusting device is pushed to slide along the first waist-shaped hole 111. Because the second linkage rod 4 rotates towards the first installation seat 1, the second pin shaft 41 can be driven to rotate towards the first installation seat 1, and then when the window sash rotates towards the window frame, the rotating shaft (the second pin shaft 41) of the window sash moves towards the direction of the window frame, so that the distance between the window sash and the window frame is reduced, and the sealing performance between the window sash and the window frame is enhanced. When the eccentric adjusting bolt 33 is rotated, the eccentric screw 333 is located at an eccentric position, and therefore the screw shaft 332 is rotated about the eccentric screw 333. Therefore, the position of the rotating axis of the first linkage rod 3 can be adjusted, so that when the window sash is closed, the distance between the window sash and the window frame is adjusted, and the tightness between the window sash and the window frame is adjusted.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
