Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 and fig. 2, the present invention provides an embodiment, a splicing mechanism of an LED display screen, including a box body 10 and a plurality of bolts 20. The multi-section bolt 20 comprises a head part 21 and a rod part 22 which are connected with each other; the rod portion 22 is provided with a stopper rod 221, a positioning rod 222, and a threaded rod 223 in this order in a direction away from the head portion 21. One side of the box body 10 is provided with a limiting hole 11, the other side is provided with a positioning hole 12 and a threaded hole 13, and an inner end opening of the positioning hole 12 is communicated with an outer end opening of the threaded hole 13.
