[0002] Engineering labor refers to the labor subcontracting operations involved in the construction of large-scale infrastructure projects such as roads, railways, bridges, ports, water conservancy projects, power stations, subways, and house buildings. Due to the relatively complex environment of engineering construction, in order to improve the safety of the project, construction units usually install safety warning devices at the entrance of the construction site, construction lifting machinery, temporary power facilities, the edge of the foundation pit and other dangerous areas to prevent pedestrians from mistakenly entering and causing safety accidents.

[0003] In a Chinese patent with publication number CN220927604U, a safety warning device for traffic facility installation engineering is disclosed. When in use, the adjusting bolt on the fixed plate can be rotated, so that the threaded block drives the adjusting plate to cooperate with the fixed plate to fix the position of the device, achieving the effect of convenient use and easy carrying. Through the setting of the limit assembly and the extension assembly, the limit block can be pressed to compress the telescopic spring to adjust the distance between the extension plate and the hollow plate when in use, achieving the effect of increasing the warning range and enhancing the warning force;

[0004] After searching and studying, and combining with actual work experience, the safety warning devices proposed in the above-mentioned comparative documents still have some shortcomings when implemented: First, the device can only serve as a warning, but does not have the function of interception, which is not convenient for blocking and isolating pedestrians who do not pay attention to the device and mistakenly enter the dangerous area of ​​the project. Moreover, it is only equipped with reflective tape, which can only provide reflective warnings under the premise of direct light, and it is difficult to provide a more eye-catching warning effect for passing pedestrians at night. Therefore, it is urgent to improve the existing safety warning device and provide a construction labor safety warning device. Utility Model Content

The end of the movable block 32 away from the threaded rod 31 is slidably sleeved on the outer side of the mounting column 2. The front end of the movable block 32 is hinged with the first connecting rod 33. The front end of the first connecting rod 33 is rotatably connected to the second connecting rod 34. The fixed block 35 is fixedly sleeved on the outer side of the bottom end of the mounting column 2.

[0030] On the basis of the above structure, the first connecting rod 33 and the second connecting rod 34 are of equal length and are arranged in an “X” shape, and the bottom end of the second connecting rod 34 is hingedly connected to the fixing block 35 .

[0031] On the basis of the above structure, the first connecting rod 33 and the second connecting rod 34 are both arranged equidistantly in the horizontal direction, and the two correspond one to one.

[0032] In this embodiment, by manually rotating the threaded rod 31 and controlling the movable block 32 to move vertically downward along the mounting column 2, the first connecting rod 33 and the second connecting rod 34 can be rotated, which facilitates the control of multiple groups of positioning support mechanisms 4 to unfold in the horizontal direction, thereby achieving isolation and interception of pedestrians.
