[0005] Furthermore: the first channel steel is selected from 12.5# channel steel, and the width of the sliding groove opened on the first channel steel is 2~3cm.

[0006] Furthermore: the second channel steel is selected from 10# channel steel, and the channel steel block is selected from 6cm×6cm 8# channel steel.

[0007] Furthermore, bolt holes are provided on both the first and second steel plates.

[0008] Furthermore: the channel steel block is welded onto the second channel steel.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0010] This invention features two channel steels of different specifications. The fixing bolts on the channel steel blocks of the second channel steel are located within the grooves of the first channel steel, forming an adjustable device. By sliding either channel steel, it can accommodate openings in exterior wall panels of different sizes, making it highly versatile. This device can also be reused repeatedly, and on-site construction is simple, facilitating installation and reinforcement. Attached Figure Description
