A locking groove 1 is provided on the locking plate 15, and a socket is provided in the connecting groove 11. The block 48 corresponds to the socket, and the block 48 is a secondary fixation of the stretching device 2. The armrest 44 is rotated in the opposite direction to separate the locking blocks at the lower ends of the large arc rack 45 and the small arc rack 46 from the grooves on both sides of the limit box 49. When the handle 35 is pushed up and the cover cap 341 passes the limit block 345, the cover cap 341 can be fixed above the limit block 345. As the stretching device 2 extends, the distance between the working plates on both sides becomes larger, and the banner 32 is unfolded. Fluorescent powder is added to the banner 32, which can also remind people at night. When the stretching device 2 begins to shrink, the clockwork spring 33 shrinks the extended banner 32 on the connecting rod 1 37 to prevent the banner 32 from being scattered. The handle 35 is pushed upward again to make the elliptical wheel 342 above the limit block 345. When the elliptical wheel 342 moves downward, because the cover cap 341 is a hollow structure, the elliptical wheel 342 will be inside the cover cap 341, and the elliptical wheel 342 can compress the spring 346 and telescopic rod 347 at the left end of the limit block 345, causing the cover cap 341 to move downward. An alarm speaker 13 is installed on the support base 1, and a switch alarm 12 is installed at the front end of the lock box 16. When the switch alarm 12 is pressed, the alarm speaker 13 will make a sound to spread the information to others. A fixing plate 51 is installed on each end of the left and right sides of the support base 1 and the locking box 16. The fixing plate 51 is connected to the ground through expansion screws, and the support block 52 is connected to the mounting frame 55 through bolts. The other end of the left support plate 53 is connected to the support base 1 through bolts, and the other end of the right support plate 53 is connected to the locking box 16 through bolts, which can increase the supporting force. The fixing plate 2 54 is connected to the ground through expansion screws to increase the stability of the device.
