[0002] When constructing highways or railways, if mountains obstruct the way, tunnels need to be excavated through them. Tunnel construction may present some dangers, so warning devices need to be installed at the tunnel construction sites to keep unrelated personnel away from the construction area.

[0003] Existing tunnel warning devices are generally fixed frames with light signs attached. However, these frames are usually fixed tripods, which cannot be folded down to reduce volume, making transportation difficult. Furthermore, the length of the frame cannot be extended. This results in the warning frames being either too small or too large when placed during tunnel construction. To address these shortcomings, this utility model proposes a tunnel construction warning device. Utility Model Content

[0007] A further improvement is that the first telescopic component is composed of an inner sleeve and an outer sleeve that telescopically fit together. When the inner sleeve and the outer sleeve telescopically extend or retract, they are fixed by a first L-shaped positioning rod. The inner sleeve has a plurality of first adjustment holes spaced apart on its body. The first telescopic component has the same structure as the second telescopic component.

[0008] A further improvement is that the first support component includes a fixed base, on which a movable outer tube is hinged, and a telescopic inner tube is movably fitted at the lower end of the movable outer tube. The movable outer tube and the telescopic inner tube are fixed by a second L-shaped positioning rod after being fitted together. A tapered plug is provided at the lower end of the telescopic inner tube, and multiple second adjustment holes are spaced apart on the telescopic inner tube. The first support component and the second support component have the same structure.
