Referring to Figure 3 , elastic plates 821 for abutting against the longitudinal beam 1 are bent upward at both ends of the bottom plate 82. Elastic plates 821 are bent at both ends of the bottom plate 82, and the elastic plates 821 gradually incline toward the top plate 81 in a direction away from the bottom plate 82. When the fixing member 84 is tightened against the longitudinal beam 1, the fastening force between the U-shaped plate and the longitudinal beam 1 can be enhanced through the self-deformation of the elastic plates 821. Thus, the stability of the U-shaped plate fixed on the longitudinal beam 1 is improved.
