[0007] A base, on the top of which a limiting plate is fixedly installed, and the limiting plate has a slot that matches the bottom of the warning sign.

[0008] A top plate is set at the top of the warning sign body. A pair of clamps are fixedly installed on the lower surface of the top plate. The distance between the two clamps is adapted to the thickness of the warning sign body. Support rods are rotatably installed at both ends of the top plate in the length direction.

[0009] The base has a pair of positioning grooves that are adapted to the support rod.

[0010] Preferably, the base has a threaded hole, a fastening bolt is threaded into the threaded hole, and the support rod has a through hole.

[0011] Preferably, one of the rotating connections between the support rod and the top plate is located above the top plate, and when the support rod is in a horizontal state, one side of the support rod is in contact with the upper surface of the top plate.

[0012] The other support rod is connected to the top plate at a point below the top plate, and when the support rod is rotated to a horizontal position, one side of the support rod is in contact with the bottom end of the clamping plate. Beneficial effects
