[0023] The connecting assembly 6 comprises a directional hole 61 formed on the surface of the connecting block 3, a spring 62 is fixedly connected in the directional hole 61, one end of the spring 62 is fixedly connected with a limiting column 63, the outer surface of the limiting column 63 is provided with a threaded structure 64, the surface of the square piece 5 is provided with a fixed hole 7 matched with the limiting column 63, one end of the limiting column 63 penetrates through the fixed hole 7 and is threadedly connected with a nut 8 through the threaded structure 64, when the square piece 5 is clamped in the square groove 4, the directional hole 61, the fixed hole 7 and the limiting column 63 are on the same horizontal axis, in the embodiment, the nut 8 and the threaded structure 64 are provided with an anti-loosening washer 9, the anti-loosening washer 9 is made of elastic metal material, and the surface of the anti-loosening washer 9 is provided with anti-skid lines engaged with the nut 8.

[0024] In the embodiment, the connecting blocks 3 are symmetrically distributed on the inner side walls of the U-shaped hollow structures of the A aluminum material 1, and form vertical supports with the square pieces 5 of the B aluminum material 2, so as to limit the distribution of the connecting blocks 3 and clearly define the support relationship. The two connecting blocks 3 are symmetrically distributed to provide bidirectional support and resist the torque of the splicing joint. The distance between the two connecting blocks 3 is 50 mm, and the contact surface with the square piece 5 is a plane with a perpendicularity error of ≤0.1 mm.
