[0039] The working principle of a highly stable safety warning device disclosed by the present utility model is as follows: When in use, first fix the promotional canvas with warning slogans between the installation frame 101 and the fixed frame 102. According to the usage requirements, if it is not desired that the frame assembly rotates around the height adjustment assembly, the first installation flange 105 and the second installation flange 209 need to be fixedly connected by bolts and nuts. Pull out the second telescopic tube 203 from the first telescopic tube 201. After adjusting to the required height, insert the bolt into the through holes that coincide with each other on the first telescopic tube 201 and the second telescopic tube 203 to fix the first telescopic tube 201 and the second telescopic tube 203. Next, adjust the opening angles of multiple leg assemblies. The adjustment method is to make the movable hinge plate 202 slide on the first telescopic tube 201. At this time, the first rotary buckle 210 and the second rotary buckle 211 are in a loosened state. The movable hinge plate 202 drives the guide sleeve 302 to rotate on the fixed hinge plate 205 through the fixed-length connecting rod 204 or the first adjusting rod 206, the second adjusting rod 207, the setscrew 208 and the hinge seat 301. The fixed-length connecting rod 204 has a fixed length. If the leg assemblies are all connected by the fixed-length connecting rod 204, the angles between multiple leg assemblies and the height adjustment assembly are the same. The purpose of setting the first adjusting rod 206, the second adjusting rod 207 and the setscrew 208 is to adjust the total length of the first adjusting rod 206, the second adjusting rod 207 and the setscrew 208 to adjust the angle of a certain leg assembly, so as to adapt to use on uneven ground and enhance stability. After adjusting the angle, screw the second rotary buckle 211 into the first rotary buckle 210. The top of the second rotary buckle 211 is squeezed between the first rotary buckle 210 and the first telescopic tube 201, and the fixation of the first rotary buckle 210 is achieved through friction, thereby achieving the fixation of the movable hinge plate 202. The leg assembly can realize length adjustment by placing the fixed pin 304 on the leg 303 into different branches to adapt to different usage heights. In strong wind weather, the resistance is reduced and tipping is prevented by the rotation of the installation frame 101 on the support frame 103 and the rotation of the support tube 104 on the second installation flange 209.
