[0017] In this embodiment, a plurality of arc-shaped support arms 6 are rotatably connected to each vertical frame 5. The arc-shaped support arms 6 can rotate around the rotation connection between their arm bodies and the vertical frame 5. The tops of the arc-shaped support arms 6 on both sides can abut against a pair of aviation parts on the support plate 3, so that the welds of the pair of aviation parts are aligned and abutted. The arc-shaped support arms 6 are fixed and limited by the locking assembly to fix the pair of aviation parts.

[0018] As an embodiment of the present invention, each set of locking assemblies includes: a side plate 4, which is arranged at a position close to the bottom on the vertical frame 5; a plurality of threaded rods 8, which penetrate and slide on the side plate 4, and one ends of the plurality of threaded rods 8 are rotatably connected to the plurality of arc-shaped support arms 6; a plurality of locking nuts 11, which are threadedly connected to the plurality of threaded rods 8, and the locking nuts 11 are located on the side of the side plate 4 away from the arc-shaped support arms 6.
