A base 5 is provided at the lower end of the fixed barrel 4, and the base 5 is welded and fixed to the fixed barrel 4. The reduction motor 6 is located between the lower end inside the fixed barrel 4 and the base 5. The fixed barrel 4 and the base 5 wrap and protect the reduction motor 6. While wrapping and protecting, the orientation of the upper shell 1 and the glass 2 can be adjusted to improve the warning range.

[0027] Working principle: When using the warning board placed inside the shell 1 to warn around the construction site, start the reduction motor 6. The output shaft of the reduction motor 6 can drive the first connecting shaft 10 to rotate through the second transmission rod 12. The first connecting shaft 10 can drive the second transmission piece 9 to rotate under the support of the support block 11, so that the inclined second transmission piece 9 rotates around the second transmission rod 12. The rotation of the second transmission piece 9 can drive the first transmission piece 8 with the second tooth groove 14 to rotate through the first tooth groove 13, so that the first transmission piece 8 rotates back and forth at a constant speed. The first transmission piece 8 can drive the second connecting shaft 15, the first transmission rod 7 and the connecting piece 3 at the upper end to rotate. The rotation of the connecting piece 3 can drive the shell 1 and the glass 2 to rotate back and forth at a constant speed, so that the shell 1 and the glass 2 rotate back and forth around the reduction motor 6, and the rotation can improve the safety warning range.
