The door and window frame 1 is rectangular, and there are four cavities 11. The four cavities 11 are located inside the four sides of the door and window frame 1 near the edges and extend along the length of the four sides of the door and window frame 1. The side of the door and window frame 1 has four elongated holes 12 that communicate with one end of the corresponding cavity 11. Each of the four sides of the door and window frame 1 has a through hole 13 that communicates with the middle of the other end of the corresponding cavity 11. The elongated holes 12 extend along the cavities. Extending along the length direction, a long rod 2 is inserted through the cavity 11. One end of the long rod 2 is located inside the through hole 13, and the other end is bent and extends out of the long hole 12. A rubber sleeve 7 is fitted on the end of the long rod 2 that extends out of the long hole 12. An abutment 3 is provided on the long rod 2 at the position inside the cavity 11. When the long rod 2 moves out of the through hole 13, the abutment 3 can press against the cavity wall of the door and window frame 11. A buffer rubber ring 6 is fixed at the position of the cavity wall of the cavity 11 at one end of the through hole 13. The long rod 2 passes through the middle of the buffer rubber ring 6.

[0026] like Figures 3 to 5 As shown, the abutment 3 includes a mounting frame 31 that is sleeved on the long rod 2 and can slide on the long rod 2. The mounting frame 31 includes a ring 311 sleeved on the long rod 2. Several mounting rods 312 extending radially along the long rod 2 are evenly spaced on the outer circumference of the ring 311. Two adjacent mounting rods 312 on the mounting frame 31 are connected by a reinforcing rod 35. The mounting rod 312 is L-shaped. The end of the mounting rod 312 has a mounting part 312a extending along the length direction of the long rod 2. The mounting part 312a has a mounting hole 312a1. An abutment rod 32 passes through the mounting hole 312a1. The abutment rod 32 is arranged radially along the long rod 2. A telescopic spring 33 is sleeved on the abutment rod 32. The two ends of the telescopic spring 33 are respectively fixed to the mounting part 312a and the abutment rod 32.

[0027] like Figures 1 to 5As shown, the long rod 2 is provided with several mounting brackets 31, which are spaced apart along the length of the long rod 2. Adjacent mounting brackets 31 are connected by connecting rods 34. The long rod 2 is provided with wedge-shaped blocks 4 extending from one end to the other. Each mounting bracket 31 corresponds to several wedge-shaped blocks 4. Several abutting rods 32 on each mounting bracket 31 are set one-to-one with the corresponding wedge-shaped blocks 4. Each long hole 12 on the side of the door and window frame 1 is provided with several insertion holes 14 communicating with the long hole 12. The insertion holes 14 are evenly spaced along the length of the long hole 12, and a stop block 5 for preventing the long rod 2 from resetting is inserted in one of the insertion holes 14. The cavity 11 has a rectangular cross-section. Each mounting bracket 31 is provided with four mounting rods 312 and four abutting rods 32. The four abutting rods 32 extend toward the four corners of the cavity 11 respectively. Each mounting bracket 31 corresponds to four wedge-shaped blocks 4.

[0028] like Figures 3 to 5 As shown, a number of strip-shaped sliders 21 corresponding to the mounting brackets 31 are provided on one side of the outer circumference of the long rod 2. The strip-shaped sliders 21 extend along the length direction of the long rod 2 and are distributed at intervals along the length direction of the long rod 2. Each mounting bracket 31 has a through groove 311a on the ring 311 for the corresponding strip-shaped slider 21 to be inserted.

[0029] Working principle: After the doors and windows are installed on the building, the workers manually move the long rod 2 within the cavity 11 until one end of the long rod 2 extends out of the through hole 13 and abuts against the wall. At this time, the wedge block 4 on the long rod 2 will drive the abutment rod 32 to move against the corner of the cavity wall 11 against the cavity wall, thereby increasing the strength of the door and window frame 1 and improving the crack resistance of the doors and windows. Then, the stop block 5 is inserted into the corresponding socket 14 to hold the long rod 2 in place and prevent it from resetting, thereby improving the firmness of the connection between the door and window frame 1 and the building and thus improving the safety of the doors and windows.
