During specific use, the formwork support requirements of beams of different specifications can be met by freely assembling standard parts of the main vertical pole and the adjustable top and bottom supports and freely switching between different gears on the limit cross bar. At the same time, due to its flexible installation and disassembly characteristics, the efficiency of formwork support and dismantling is greatly improved.
