Iron clamp

The utility model belongs to a tool used for packing and in particular the utility model relates to an iron clamp. The two ends of the elastic iron clamp of the safety iron clamp are equipped with reversal curve slots; the places on the two ends of the iron clamp and close to the curve slots are provided with screw holes. The width of the iron clamp is 45 to 55mm. The utility model can be applied on the packing box of large size; when being used, the iron clamp is buckled in the corresponding slot of the packing box body and fixed by screws. The utility model enables the iron clamp and the packing box to be formed into complete integration and overcomes the disadvantages existing on the present technology by changing the structure of the iron clamp and increasing screw fixing. When the utility model is adopted, the process is safe no matter in the process of disassembling and assembling or in the process of conveying, the iron clamp can not fly out to hurt people. The packing box adopting the utility model is uneasy to be lifted to enable the conveying products to be safer. The width of the utility model is wide and the strength is reinforced and thus to the using on the packing box of large size, the problem of packing safety can be solved by only using a minority of iron clamps and thus the disassembling and the assembling are convenient and rapid to enable the entire product structure to be more reasonable.
