The fixed plate 313 and the connecting block 314 are integrally formed, and the fixed plate 313 and the top surface of the horizontal plate 311 and the rear side of the vertical plate 312 are spaced apart from each other to form an L-shaped channel for clamping the support beam 2, preventing the support beam 2 from moving.

[0039] As shown in Figures 4-5 , the flipping mechanism 32 includes a flipping arm 321 and a rib 322; the flipping arm 321 is provided with two, and the two flipping arms 321 are arranged at intervals. The upper part of the two flipping arms 321 and the upper part of the connecting block 314 are provided with horizontal through holes, and the flipping arm 321 and the connecting block 314 are hinged through a pin shaft. The lower part of the flipping arm 321 is bent downward; the rib 322 is arranged between the two flipping arms 321, and the two ends are fixedly connected with the opposite sides of the two flipping arms 321. By rotating the flipping arm 321 downward based on the connecting block 314, the flipping arm 321 drives the pressing mechanism to rotate downward.
