The structure is simple, so as to facilitate the construction of the staff and improve the work efficiency.

[0010] Optionally, the baffle is polygonal in shape, and the inner plate is provided with an insertion slot on the side away from the outer wall for inserting the baffle.

[0011] By adopting the technical scheme, by setting the baffle as a polygon and inserting it into the insertion slot, the situation that the connecting column rotates freely after being inserted into the mounting hole can be reduced, so as to facilitate the staff to hold the connecting column to rotate the threaded sleeve.

[0012] Optionally, the inner plate is provided with a limiting piece at both ends, and the two limiting pieces are respectively used to abut against the sides of the two reinforcing steel bars of the reinforcing cage that are close to each other.

[0013] By adopting the technical scheme, by setting the limiting pieces at both ends of the inner plate and abutting the limiting pieces against the reinforcing steel bars, the situation that the inner plate freely slides in the reinforcing cage can be reduced, so as to increase the stability of the reinforcing cage during hoisting.

[0014] Optionally, the inner plate comprises a plurality of sub-plates, and adjacent sub-plates are rotationally connected by hinges.

[0015] By adopting the technical scheme, when the length of the inner plate is relatively long, the inner plate is provided as a plurality of sub-plates, so as to facilitate the staff to arrange the inner plate in the reinforcing cage and improve the installation convenience.

[0016] In summary, the present application has at least one of the following beneficial technical effects:

[0019] 3. By setting the limiting pieces, the two limiting pieces are respectively abutted with the two steels, which can reduce the free sliding of the inner plate in the steel cage, thereby increasing the stability during the lifting process of the steel cage. BRIEF DESCRIPTION OF DRAWINGS
