Each extension plate 13 is slidably connected with the groove provided inside the advertising board 1 through the protrusions on both sides. This structure can quickly install and limit the extension plate 13 through the internal groove of the advertising board 1 and the protrusions on both sides of the extension plate 13.

[0021] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, each advertising board 1 is provided with limit holes 12 on both sides, and two connecting rings 16 are fixedly installed on both sides of the capping cover 15. This structure can be conveniently installed with subsequent devices through the limit holes 12 provided on the advertising board 1.

[0022] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, a bolt 17 is installed inside each connecting ring 16, and the capping cover 15 is installed above the two advertising boards 1 by means of the connecting ring 16, the bolt 17 and the limiting hole 12, while limiting the advertising boards 1. This structure can cooperate with the connecting ring 16 and the bolt 17 through the limiting hole 12, so as to quickly assemble the capping cover 15 for convenience in subsequent use.

[0023] In this embodiment, Figure 1 and Figure 3 As shown, the upper ends of every two threaded rotating rods 2 that are close to each other are sleeved with the same transmission belt 21, and the upper end of one of the threaded rotating rods 2 is rotatably installed with a rotating motor 22. This structure can drive the four threaded rotating rods 2 to rotate by the rotating motor 22 cooperating with the transmission belt 21, thereby facilitating the adjustment of the height position of subsequent parts such as the ring 23.

[0024] In this embodiment, Figure 1 and Figure 4As shown, a support base 27 is provided inside each limit frame 25, and each limit frame 25 cooperates with the support base 27 through a fixing buckle 14 to be slidably connected with the extension plate 13. This structure can connect and support the device through the support base 27 provided inside the limit frame 25 and the fixing buckle 14.

[0025] The use method and advantages of the utility model: When the railing assembly with a quick-release structure is used, the working process is as follows:

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, first, when the user is using it, the device is placed on a horizontal plane. The user picks up two advertising boards 1 and installs two extension boards 13 between the two advertising boards 1. Then, the fixing buckles 14 are fixed on the side ends of the two extension boards 13. Then, the limiting frame 25 is picked up and the upper limit groove 26 is installed under the limiting frame 25. After assembling the two limiting frames 25, the two limiting frames 25 are matched with the supporting base 27 opened inside and the fixing buckles 14 to be installed to the side ends of the two extension boards 13. Then, the user picks up the capping cover 15 and installs two connecting rings 16 on the left and right sides of the capping cover 15 respectively. Then, the bolts 17 are installed in the two connecting rings 16. Then, the assembled capping cover 15 is matched with the bolts 17 and the connecting rings 16 and the limiting holes 12 opened above the two advertising boards 1, so that the capping cover 15 is installed and the advertising board 1 is fixed at the same time. Then, the user installs two threaded rotating rods 2 on the left and right sides of the capping cover 15, and installs the same transmission belt 21 above the two threaded rotating rods 2. Then, on one of them, A rotating motor 22 is installed above the threaded rotating rod 2, and then a sleeve ring 23 is sleeved on the outer surface of the four threaded rotating rods 2, and then the two sleeve rings 23 are connected with a cleaning cotton 24 at a position on one side of the reserved groove 11 along the advertising board 1. When the user needs to use the device, the user places the device at a designated position, and then pulls the limiting frames 25 on both sides to slide the extension plate 13 and the inside of the two advertising boards 1 to the edge. At this time, the width of the device can be extended, and the user can post posters in the reserved groove 11 opened inside the advertising board 1. When the posters posted in the reserved groove 11 are contaminated after the device is used for a long time, the user starts the rotating motor 22, and the rotating motor 22 cooperates with the transmission belt 21 to drive the two threaded rotating rods 2 to rotate. The two rotating motors 22 rotate at the same time to drive the four sleeve rings 23 to move up and down on the outer surface of the threaded rotating rod 2. At this time, the cleaning cotton 24 connected to the side end of the sleeve ring 23 can be cooperated to clean the advertising board 1 and the reserved groove 11, thereby cleaning and wiping the outer surface of the poster.
