At this time, the limit block 403 is engaged with the next limit groove 405, and the position of the connecting block 302 on the cross 301 is fixed. If at this time, the fixing angle of the connecting block 302 is not what is needed, the connecting rod 303 is continuously rotated to make the elastic connecting plate 402 deform and tilt under continuous force, and the limit block 403 will continuously break away from the engagement with the current limit groove 405 and engage with the next limit groove 405 until the connecting block 302 is rotated to a suitable angle (such as Figure 1 As shown), at this time, the bottom plate 1 is fixed to the wall by bolts, and the LED splicing screen is fixed and spliced ​​by the clamping mechanism on the cross 301. When the mounting bracket needs to be transported, the LED splicing screen is removed from the mounting bracket, and the bottom plate 1 is removed from the wall. Then, the connecting rod 303 is rotated to make the connecting block 302 rotate in the opposite direction on the cross 301 through the rotating shaft until the mounting bracket is folded into its original shape (as shown).
