The movement of the lock handle 10 drives the two second door and window frames 7 and the first door and window frame 2 connected to the second door and window frames 7 to rotate until the first door and window frame 2 rotates to a vertical position. Next, rotate the two grips 5 respectively. The rotation of the two grips 5 drives the two screw rods 4 to rotate respectively. The rotation of the two screw rods 4 drives the two connecting blocks 6 to move upward respectively. The two second door and window frames 7 are driven to move upward through the connecting blocks 6 until the second door and window frame 7 moves upward to a suitable height. In this way, the doors and windows can be adjusted to make way, thereby greatly reducing their occupied area in the room, reducing the occurrence of collisions between people and doors and windows, and avoiding injuries to the human body. When the doors and windows are in a closed state, the sealing of the doors and windows can be increased by the protective strip 101, which can effectively prevent wind and water.
