[0064] At this time, the fixing plate 1 is temporarily fixed, and the top of the vertical plate 13, the connecting plate 14, and the vertical plate 2 15 are buckled on the top of the concrete beam, playing the role of a hook. During the process of the fixing plate 2 2 being connected with the fixing plate 1, the fixing plate 1 will not shift, and the sleeve 5 will not be separated from the hole.
