Then, insert the bracket screw 9 into the hole and tighten it with threads to connect and fix the mounting bracket 6, the footrest 4 and the drone body 1. At this time, install the connecting bracket 7 on the surface of the mounting bracket 6, and connect a set of fastening nuts 14 to the threaded rod 12 with threads. Then, align the insertion hole 13 on the second side plate 11 with the threaded rod 12 fixed on the first side plate 10, so that the threaded rod 12 is inserted into the insertion hole 13 and passes through the surface of the second side plate 11. Then, connect another set of fastening nuts 14 to the threaded rod 12 with threads, so that the two sets of fastening nuts 14 are placed on both sides of the second side plate 11. After adjusting the position and height of the mounting platform 8, tighten the two sets of fastening nuts 14 so that they abut against both sides of the second side plate 11 to complete the installation and adjustment of the fixed bracket.
