When inserting, an external rod can be used to insert into the access slot 1011 to push the top of the billboard a. The bottom of the billboard a presses down the pushing bar 701, and at the same time compresses the second spring 702 until the bottom of the pushing bar 701 fits against the top surface of the stop post 703. At this time, the inserting block 705 is aligned with the second slot 602, and the inserting block 705 is driven by the elastic force of the third spring 704 to insert into the second slot 602 to position the pushing bar 701, completing the installation of the billboard a.

[0058] As Figures 4-6 shown, the number of the locking parts is two, and the two locking parts are symmetrically arranged on both sides of the top cover 3. The locking part includes a first guide groove 302, an inclined block 303 and a first spring 304. The first guide groove 302 is opened on the side wall of the top cover 3. The inclined block 303 is connected with the first guide groove 302 in a matching manner, and a first spring 304 is arranged in the first guide groove 302. The inclined block 303 is elastically connected with the top cover 3 through the first spring 304. The bottom and top of the end of the inclined block 303 outside the first guide groove 302 are respectively provided with an inclined surface and a flat surface, and the end of the inclined block 303 outside the first guide groove 302 is inserted into the first slot 1012 opened on the side wall of the access slot 1011. A chamfer 1013 adapted to the inclined surface of the inclined block 303 is provided at the top side of the access slot 1011. The unlocking mechanism 9 includes a movable column 901, an iron rod 902, a magnetic block 903, a fifth spring 904, a positioning hole 905, a stop block 906 and a guide sleeve 907. A stop block 906 is fixedly connected to the center of the top surface of the bottom groove 301. A vertical positioning hole 905 is opened in the middle of the stop block 906, and the positioning hole 905 extends into the top cover 3. The movable column 901 is connected with the positioning hole 905 in a matching manner, and a fifth spring 904 is arranged in the positioning hole 905. The movable column 901 is elastically connected with the top cover 3 through the fifth spring 904. A magnetic block 903 is fixedly connected to the bottom end of the movable column 901. An iron rod 902 is arranged on both sides of the bottom of the stop block 906. A guide sleeve 907 is sleeved on the iron rod 902, and the guide sleeve 907 is fixedly connected to the top surface of the bottom groove 301.

The iron rod 902 penetrates through the through holes, and the iron rod 902 is fixedly connected with the inclined block 303.

[0059] As Figures 4-6As shown, the locking part is in the locked state at this time. When moving on the billboard a, it is inserted into the bottom groove 301. The top of the billboard a pushes the magnet block 903 and the movable column 901 to move upward together. The movable column 901 penetrates into the positioning hole 905, and at the same time compresses the fifth spring 904 to generate a compression elastic force until the magnet block 903 contacts the stopper 906. The magnet block 903 moves between the two iron rods 902, magnetically attracts the iron rods 902, and the two iron rods 902 drive the inclined block 303 to move. The inclined block 303 is pulled out from the first slot 1012, realizing the automatic unlocking of the locking part. After unlocking, the top cover 3 and the billboard a move upward together and leave the access slot 1011.

[0060] After the top cover 3 is unlocked, the elastic force of the fifth spring 904 can drive the magnet block 903 to reset. After the fifth spring 904 is compressed, it has a large enough elastic force to overcome the magnetic attraction between the magnet block 903 and the iron rods 902.

[0061] Among them, the magnet block 903 is made of a permanent magnet.

[0062] Furthermore, as Figure 7 shown, cutting edges 305 are provided at the bottom edges on the front and rear sides of the bottom groove 301.

[0063] Through the design of the cutting edges 305, during the process of inserting the billboard a into the bottom groove 301, the cutting edges 305 are used to peel off the top of the advertising sticker b from between the billboard a, facilitating the subsequent tearing off of the advertising sticker b on the billboard a and then pasting a new advertising sticker b. It provides convenience for the replacement of the advertising sticker b.

[0064] The billboard a adopts a hard plate structure, such as a hard plastic plate; it can be reused.
