形したりする。In the prior art 3, the hook f of the frame hooking piece d is hooked to the lower end of the side of the frame to prevent the hook from coming off. On the other hand, the height of the side of the top is not uniform depending on the manufacturer of the column g. For this reason, when the length of the frame hooking piece d to the hook f is shorter than the height of the frame side, not only the hook f cannot be hooked on the lower edge of the frame side but also the frame hooking piece d and the insertion piece b. And the brace end h cannot be fixed to the top a. If the length of the frame hooking piece d to the hook f is longer than the height of the frame side, when the frame holding means is fixed, the frame hooking piece d
d cannot be hooked to the lower edge of the side of the frame. Even when the upper portion of the frame hooking piece d is pivotally supported in the oblong hole so as to be freely movable (refer to the embodiment of the prior art 3), the frame hooking piece d of the preceding and succeeding technology 3 is used to clamp the side surface of the frame. Because the hook f must be hooked to the lower edge of the top of the top, the length of the top hook piece d to the hook f and the height of the top of the top must be in a fixed relationship, causing the same problem. . When the lower end of the wedge piece e is beaten when the wedge piece e is removed, a pulling force acts on the frame hooking piece d that is in sliding contact with the wedge piece e. This force is transmitted directly to the lower edge of the side surface of the frame hooked through the hook f. Therefore, the lower edge of the side surface of the top is crushed or deformed.
