[0002] During the reconstruction and expansion project of expressways, it is necessary to set up temporary signs on the road section to inform drivers of information such as road closures ahead, playing a role of warning and guiding. At present, for the fixation of temporary signs, commonly, the sign pole is inserted into the soil on the side of the road and fixed to the guardrail column with steel wires. However, under the influence of strong winds or rainy weather, it is easy to rotate or fall, and the normal use cannot be guaranteed. And adopting the welding form with the guardrail column, although the reliability of the fixation is ensured, the disassembly is difficult and the column will be damaged. Therefore, there is an urgent need for a device that can reliably fix the sign and is convenient for disassembly. Summary of the Utility Model
