In actual installation, the upper connection plate frame 10 and/or the lower connection plate frame 20 may be directly fixedly connected to the connection bracket 231 to achieve connection with the central shaft 1.

When the side LED display module 33 needs to be extended, the side driving motor 2342 in the side telescopic driving assembly 234 provides driving force, the driving side gear 2343 rotates in the forward direction, and since the side driving motor 2342 and the side gear 2343 are fixed in position, the rotation of the side gear 2343 causes the side rack 2341 to drive the side telescopic push rod 233 and the side slide rail 2322 to slide linearly to the outside along the side slider 2321, and then the side LED display module 33 is pushed linearly to the outside by the side telescopic push rod 233, so that the side LED display module 33 is extended as a whole, as shown in fig. 14.

Example two

The main differences between this embodiment and the first embodiment are: as shown in fig. 10, 11 and 13, the side retractable push rod 233 and the side LED display module 33 are connected by a universal swivel support 235, specifically, as shown in fig. 10 and 11, the universal swivel support 235 mainly comprises a connection back plate 2351 connected to the end of the side retractable push rod 233, and a multi-angle swivel head 2352 rotatably disposed on the connection back plate 2351 and connected to the side LED display module 33, wherein the connection back plate 2351 is connected to the middle of the multi-angle swivel head 2352 by a tightness adjusting screw 2353, and a screw cover 2354 is disposed on the tightness adjusting screw 2353; the multi-angle rotating head 2352 has several connecting arms 23521 extending from the side, the side mounting bracket 331 of the side LED display module 33 is fixedly connected to the connecting arm 23521, specifically, several screw holes 235211 are formed on the connecting arm 23521, and the side mounting bracket 331 of the side LED display module 33 is fixedly mounted on the connecting arm 23521 by screws.

In particular operation, the slack adjustment screw 2353 is loosened to facilitate rotation of the multi-angle rotator head 2352 when an applied force is applied to the multi-angle rotator head 2352, thereby adjusting the angle of the side LED display module 33; after the side LED display module 33 is angularly adjusted, the tightness adjusting screw 2353 is tightened to fix the multi-angle rotating head 2352 to the connection back plate 2351, so as to angularly fix the side LED display module 33.
