By sliding the sliding seat 42 along the length direction of the sliding rail 41, and then inserting the positioning pin 421 into the corresponding pin hole 411, the position of the sliding seat 42 is adjusted, so as to facilitate the adjustment of the distance between the two longitudinal steel beams, thereby facilitating the assembly and welding of the frame structure with different widths.

[0028] Referring to Figure 2 , Figure 3 As shown in the figure, the top of the sliding seat 42 is provided with a clamping groove for placing the longitudinal steel beam, and one side of the sliding seat 42 is provided with a pressing piece 43 for pressing against the longitudinal steel beam.
