[0027] The extension plate 3 is driven to rotate by the driving mechanism. When the extension plate 3 rotates to be level with the bottom plate of the U-shaped frame 2, the first baffle plate 4 is moved onto the extension plate 3 so that the first baffle plate 4 forms a fence. The first baffle plate 4 and the extension plate 3 expand the construction space for workers, so that workers can move and construct in the U-shaped frame 2 and the extension plate 3, and can ensure the safety of workers. Preferably, a limiter is provided on the first baffle plate 4 for limiting the first baffle plate 4 from sliding out of the extension plate 3. The limiter can be a telescopic rope connected between the first baffle plate 4 and the inner wall of the U-shaped frame 2. When the first baffle plate 4 is just moved to the outermost end of the extension plate 3, the telescopic rope just reaches the maximum extension length, thereby preventing the first baffle plate 4 from sliding out of the extension plate 3.
