[0002] Road construction warning signs are traffic warning signs used to indicate road construction ahead and alert vehicles and pedestrians to safety. Their primary function is to inform pedestrians of road construction and, for safety reasons, to slow down or take detours to reduce the risk of accidents. These signs can be placed appropriately ahead of the construction area, giving drivers and pedestrians ample time to spot the signs and take safe evasive action. Construction warning signs are used in a wide range of situations, including road construction, building construction, and solar energy projects.

[0003] In the prior art, most current road construction warning signs are fixed on brackets by welding when in use. Since the road construction warning signs have been used for a long time, the warning slogans may be worn out due to external factors and the warning slogans may not be clearly visible, making the warning signs ineffective in warning. Therefore, the warning signs on the brackets need to be replaced. However, since the warning signs are welded together with the brackets, it is inconvenient to disassemble and replace the warning signs. At the same time, the warning signs cannot be adjusted in height due to the limitations of the bracket structure. During the road construction process, various obstacles or construction equipment will block the low warning signs. In addition, in sections with limited visibility or heavy traffic, it is difficult for drivers and pedestrians to find the warning signs, which in turn affects the warning effect of the warning signs when in use.
