Two locking assemblies 8 for positioning the two auxiliary warning signs 7 are symmetrically arranged at the top of the main warning sign 2. The locking assemblies 8 ensure the stable connection between the main warning sign 2 and the auxiliary warning signs 7, and also allow the auxiliary warning signs 7 to be easily disassembled or installed when needed, increasing the flexibility of the device;

[0026] The rotating assembly 3 includes a rotating rod 301. The top end of the rotating rod 301 is rotatably installed on the inner top of the cavity 9. The bottom end of the rotating rod 301 is connected with a first driving motor 302. The top end of the rotating rod 301 penetrates through the base 1 and is fixedly connected with a turntable 303. The bottom of the positioning column 4 is fixedly connected with the top of the turntable 303;

[0027] Specifically, the output shaft of the first driving motor 302 during operation can drive the rotating rod 301 to rotate forward or backward, thereby driving the turntable 303 to rotate, so as to achieve the effect of rotating and adjusting the main warning sign 2;

Four support columns 504 are symmetrically and fixedly connected to the top of the active block 503. The top ends of the four support columns 504 all penetrate through the positioning column 4 and are fixedly connected with a lifting plate 505. And the four support columns 504 are all slidably connected with the top of the positioning column 4. The bottom of the main warning sign 2 is fixedly connected with the top of the lifting plate 505;

[0030] Specifically, the output shaft of the second driving motor 501 can drive the ball screw 502 to rotate forward or backward, thereby driving the active block 503 to make a reciprocating motion along the axial direction of the ball screw 502.
