A branch column 3 (1#), a branch column 4 (2#), a branch column 5 (3#), and a branch column 6 (4#) are respectively connected above the rotatable hinge support 2. The branch column 3 (1#) is connected to the branch column 4 (2#), and the branch column 5 (3#) is connected to the branch column 6 (4#) via a telescopic connecting device 7. A roof support device 8 is connected to the upper end of the branch column 3 (1#), the branch column 4 (2#), the branch column 5 (3#), and the branch column 6 (4#) and the roof support device 8 are fixedly connected above the roof support device 8.

[0022] The rotatable hinge support 2 includes a #1 ear plate 22, which is fixed to the top of the tree-shaped column trunk 1 by welding. U-shaped ear plates 21 are respectively provided on both sides of the #1 ear plate 22, and a #2 ear plate 23 is located in the middle of the U-shaped ear plates 21. The U-shaped ear plates 21, #1 ear plate 22, and #2 ear plate 23 are all flexibly rotated via pins 24. This structural design allows the entire tree-shaped column to achieve optimal support by adjusting its angle and height through rotation, according to the needs of different roof structures.

[0023] The retractable connecting device 7 includes a hydraulic jack 71, with steel plate supports 72 welded to both ends. I-beams 73 are welded to the steel plate supports 72 for connecting branch column 1#3 with branch column 2#4, and branch column 3#5 with branch column 4#6. By adjusting the hydraulic jack 71, the spacing between branch column 1#3 and branch column 2#4, and branch column 3#5 and branch column 4#6, can be precisely controlled to adapt to the needs of different roof structure forms.
