In the production process of autoclaved sand concrete board, it is necessary to place the concrete board keel into a mold filled with unsolidified concrete to complete the preliminary preparation of the autoclaved sand concrete board. At present, people have developed a variety of keel transfer devices to enable them to complete the keel transfer work mechanized. The existing transfer device completes the grabbing and transfer of the keel through the grabbing steel chisel installed on it and the claws on the grabbing steel chisel. Since the number of keels grabbed at one time is multiple, after the keel is grabbed, it is usually fixed to each other by winding wire between the bottom end of the steel chisel and the keel; to avoid contact between the keels, the keels are kept at a certain distance to facilitate the subsequent board cutting and prevent the problem of tool loss caused by the cutting knife touching the keel during the board cutting process.

[0003] However, when the steel bar is fixed to the keel with a cable tie, not only is there a problem of complicated operating procedures and low work efficiency; and when the keel is immersed in the concrete and solidified to a certain extent, when the steel bar is separated from the keel upward, it is very easy for the cable tie to be too tight and thus unable to separate, or it can be separated but will cause the keel to deviate or even partially take out the concrete, which will directly affect the quality of the plate. Therefore, it is necessary to develop a new grabbing steel bar for the keel transfer device of the autoclaved sand concrete plate to solve the above-mentioned existing problems.
