[0018] like Figure 1 As shown, the utility model comprises two oppositely arranged vertical plates 1, an adjusting mechanism arranged between the two vertical plates 1, and a fixing mechanism arranged on the vertical plates 1. The adjusting mechanism is used to adjust the distance between the two vertical plates 1, and the fixing mechanism is used to fix the vertical plates at a predetermined position in the door and window openings.

[0019] The adjustment mechanism includes a telescopic rod arranged between two vertical plates 1, one end of the telescopic rod is connected to one of the vertical plates 1, and the other end is connected to the other vertical plate 1. The distance between the two vertical plates 1 is adjusted by the telescopic rod, and the distance between the outer sides of the two vertical plates 1 is the predetermined size of the door and window openings. The telescopic rod 3 includes an outer rod 4, an inner rod 5 that can slide in the outer rod 4, and a locking component for fixing the outer rod 4 and the inner rod 5. The outer rod 4 and the inner rod 5 are respectively connected to one vertical plate 1. The locking component in this embodiment is a compression sleeve 7. An external thread section 6 with a gap is arranged on the outer rod 4 of the telescopic rod 3, and the external thread section 6 is arranged at one end of the outer rod 4 away from the vertical plate 1. The compression sleeve 7 is arranged on the external thread section 6. When the compression sleeve is tightened, the compression sleeve squeezes the external thread section, and the external thread section clamps and fixes the inner rod of the telescopic rod 3. The locking component can also be a pressing block, a buckle, a locking rod or a tightening rod.

[0020] There are two telescopic rods 3, and the two telescopic rods 3 are symmetrically arranged between the two vertical plates 1 to have higher stability.

[0021] The adjustment mechanism also includes a screw rod 9 horizontally arranged between the two vertical boards 1. Connecting ears 8 are symmetrically arranged at the front ends of the two vertical boards 1. The screw rod 9 is inserted into two opposite connecting ears 8. Nuts are arranged on the screw rod 9 on both sides of each connecting ear 8. The nuts are used to fix the screw rod 9 and the connecting ears 8 together. By adjusting the length of the screw rod 9 between the two vertical boards 1, the spacing between the vertical boards 1 can be adjusted. The telescopic rod 3 is located at the rear of the vertical board 1.

[0022] There are two groups of connecting ears 8 and screw rods 9, which are symmetrically arranged between the two vertical boards 1. The connecting ears 8 and screw rods 9 firmly connect the front parts of the vertical boards 1.

[0023] When in use, the telescopic rod 3 is inside the door or window opening, the connecting ear 8 and the screw 9 are located outside the door or window opening, and the telescopic rod 3 and the screw 9 jointly connect the two vertical plates 1, thereby enhancing the stability of the entire tool.

[0024] The telescopic rods 3 and the screw rods 9 are arranged alternately in the vertical direction, providing more space for construction workers to take measures and avoiding mutual interference.

[0025] The fixing mechanism includes a fixing nut 10 provided on the vertical plate 1 and a hand-tightening bolt 2 passing through the fixing nut 10 and the vertical plate 1. A hole for passing the hand-tightening bolt 2 is provided on the vertical plate 1, and the hole matches the hole of the fixing nut 10. Fixing mechanisms are provided on both vertical plates 1, and the fixing mechanisms are symmetrically arranged near the upper and lower ends of each vertical plate 1, providing uniform support force for the vertical plates and enhancing the balance and stability of the overall structure. After adjusting the distance and position between the two vertical plates 1, turn the hand-tightening bolt 2 so that the outer end of the hand-tightening bolt 2 contacts the door and window openings, and securely tighten them through the jacking force of the hand-tightening bolt 2. The fixing mechanisms are symmetrically arranged near the upper and lower ends of the vertical plates 1, ensuring the uniformity of the vertical plates 1 and enhancing the balance of the overall structure.

[0026] A level 11 is provided on the inner side of the vertical plate 1, and the level 11 enables the vertical plate 1 to quickly reach a horizontal state during installation and adjustment, thereby ensuring the flatness of the door and window openings. By integrating the level 11 on the vertical plate 1, workers do not need to carry or use other tools, thereby improving work efficiency.

[0027] The vertical plate 1 is made of a 3 mm thick stainless steel plate. The stainless steel material, with its corrosion resistance and wear resistance, ensures the stability and reliability of the vertical plate 1 in long-term use.
