When installing, if the installation position space is narrow, the distance between the first support plate 1 and the second support plate 12 can be reduced to facilitate installation, thereby increasing the flexibility of the fixing device and making it more practical. The second bolt 13 can be loosened by screwing it, and the first bolt 9 can be removed by screwing it. Then, the distance between the first support plate 1 and the second support plate 12 can be adjusted by pushing and pulling the second support plate 12. After the distance is adjusted, the first bolt 9 can be screwed on again. , and tighten the second bolt 13. A first bolt 9 is threadedly inserted into one of the threaded holes 8 on the front and back of the upper half of the first support plate 1. The outer surfaces of the two first bolts 9 are movably sleeved with connecting rods 10. The connecting rods 10 are rectangular. The rectangular design of the connecting rods 10 can make the contact surfaces of the two ends of the connecting rods 10 with the first support plate 1 and the telescopic rod 2 larger and more fit, making the connection more stable. The other ends of the two connecting rods 10 are threadedly inserted with second bolts 13. The two second bolts 13 are respectively threadedly connected to the right sides of the two telescopic rods 2.
