[0031] During specific implementation, by slidingly installing two U-shaped clips 8 on the crossbeam 1, the distance between the two U-shaped clips 8 can be flexibly adjusted according to the size of the supporting steel frame 13. At the same time, clip grooves 9 are opened on the two side plates 8-1 of the U-shaped clips 8 to facilitate the clipping of the U-shaped clips 8 and the longitudinal channel steel 13-1 on the supporting steel frame 13, thereby positioning the supporting steel frame 13.

[0032] During specific implementation, the cross beam 1, the vertical column 2, and the sliding sleeve 3 are all made of square steel.
