[0018] Depend on Figures 1 to 6 The utility model includes a device mounting seat 1, four universal movable brake wheels 2 are installed at the bottom of the device mounting seat 1, three rotating shafts 3 are rotatably connected to the top of the device mounting seat 1, and three trihedral placards 4 are fixedly installed on the surfaces of the three rotating shafts 3, an adjusting cavity 5 is opened inside the device mounting seat 1, the bottoms of the three rotating shafts 3 extend to the inside of the adjusting cavity 5 and are fixedly connected with a first bevel gear 6, the inside of the adjusting cavity 5 is rotatably connected with a rotating rod 7, three second bevel gears 8 are fixedly installed on the surface of the rotating rod 7, and the three second bevel gears 8 are respectively meshed and connected with the three first bevel gears 6, a power cavity 9 is opened inside the device mounting seat 1, a motor 10 is installed inside the power cavity 9, and a gear connected to the rotating rod 7 is installed at the output end of the motor 10 An equi-angle rotating structure 11; the equi-angle rotating structure 11 comprises a main shaft 12 fixedly connected to the output end of the motor 10, a squeezing cam 13 and a rotating round wheel 14 are fixedly mounted on the surface of the main shaft 12, and a toggle pin 15 is fixedly connected to one side of the rotating round wheel 14; one end of the rotating rod 7 extends to the inside of the power chamber 9 and is fixedly connected to an equi-angle rotating disk 16, and the circumferential surface of the equi-angle rotating disk 16 is provided with three toggle grooves 18 matching the toggle pin 15 at equal distances in an annular manner, a positioning circular block 19 is fixedly connected to the middle of one side of the equi-angle rotating disk 16, and the circumferential surface of the positioning circular block 19 is provided with three positioning holes 20 at equal distances in an annular manner, so that the three trihedral placards 4 can be driven to rotate and adjust by 60° to perform the splicing of the placards and the replacement of the slogans;

[0019] By starting the motor 10, the main shaft 12 rotates 360°, and the rotation of the main shaft 12 drives the extrusion cam 13, the rotating round wheel 14 and the toggle pin 15 to rotate 360°. The rotation of the toggle pin 15 moves to the inside of the toggle slot 18 and the equal-angle rotating disk 16, the rotating rod 7 and the positioning round block 19 rotate 60° through the toggle slot 18;

[0020] The 60° rotation of the rotating rod 7 will drive the three second bevel gears 8 to rotate the three first bevel gears 6 by 60°, so that the three first bevel gears 6 drive the three trihedral placards 4 to rotate 60 degrees, so that one side of the three trihedral placards 4 is spliced ​​into a large placard, so that the spliced ​​large placard can be used to set a larger safety warning slogan; and each trihedral placard 4 has three sides, so they can be spliced ​​into three large placards, so that more safety warning slogans can be set.

[0021] A sleeve 21 is fixedly installed at the bottom of the power chamber 9, an inverted T-shaped pin 22 is installed inside the sleeve 21, a reset spring 23 is fixedly connected between the bottom of the inverted T-shaped pin 22 and the bottom of the sleeve 21, an extrusion plate 24 is fixedly installed on the top of the inverted T-shaped pin 22, and one end of the top of the extrusion plate 24 is fixedly connected with a positioning pin 25 movably plugged into the positioning hole 20, so that the three trihedral placards 4 spliced ​​into a large placard can be effectively positioned to prevent external force from causing them to rotate;
