One end of the locking rod 29 is hemispherical and embedded in the locking groove, and the other end is provided with a regular hexagonal rotating groove. The locking rod is embedded in the positioning rod 25. The adjusting disk 27 can be limited by the locking rod so that it is not easy to slide up and down while not affecting its rotation, so that people can adjust the position of the limit rod 28 more stably.

[0028] When people install the bus duct, first determine the fixed position of the suspension rod assembly 23 according to the spatial position, adjust the position of the suspension rod assembly 23 by rotating the support plate 22, so that the installation of the suspension rod assembly 23 is convenient, and then place the bus duct on the support plate 22 and slide the bus duct to the desired position, so that the positioning rod 25 corresponds to the position of the positioning groove 111, and then rotate the rotating plate 261 to retract the limiting rod 28 into the positioning rod 25, so that the positioning rod 25 can be embedded in the positioning groove 111 under the action of the positioning spring 252, so as to realize the bus duct. Position it horizontally, and then loosen the rotating plate 261, so that the limit rod 28 is embedded in the limit groove 112 under the drive of the torsion spring 262, so that the bus duct cannot move up and down, thereby fixing the hanging frame 2 to the bus duct. When the bus duct needs to be separated from the hanging frame 2, the rotating plate 261 can be rotated first to separate the limit rod 28 from the limit groove 112, and then the bus duct can be lifted to separate it from the positioning rod 25, and the disassembly between the bus duct and the hanging frame 2 can be completed, making the bus duct easy to disassemble and easy for people to maintain and move the position of the bus duct later.
