The T-shaped nuts are installed in the T-shaped grooves and connected to the combined fixture through hexagon socket head cap screws. While causing synchronous displacement between the combined fixture and the T-shaped nuts, the number of limiting fulcrums for the combined fixture is increased, enabling it to slide while always remaining in contact with the base and avoiding its longitudinal detachment, thereby improving the structural stability. Moreover, there are machine screw jacks inside the combined fixture to fasten the aviation crossbeam products, enhancing the clamping and positioning of the aviation crossbeam products, with convenient operation and quick clamping possible.
