At the same time, the side of the rotating rod 1 3 and the rotating rod 2 4 that are away from each other will abut against the inner wall of the rectangular groove 2, thereby ensuring that the rotating rod 1 3, the rotating rod 2 4, the rotating rod 3 5 and the rotating rod 4 6 and the top plate 7 will not shake. Then, the personnel can pull out the plug plate 2 15 on the rotating rod 2 4 and the rotating rod 4 6, and insert the plurality of cross bars 10 into the plurality of round holes 9 respectively, until one end of the plurality of cross bars 10 respectively enters the rotating rod 4 When the rod 1 3 and the rotating rod 3 5 are in contact, the two plug plates 2 15 are respectively inserted into the two plug-in grooves 1 8 from one side of the rotating rod 2 4 and the rotating rod 4 6. At this time, the plurality of cross bars 10 can be limited, and then the plug plate 1 14 is pulled out from the top of the top plate 7, and the plurality of vertical rods 13 are respectively inserted into the plurality of round holes 2 12 from top to bottom, until the bottom ends of the plurality of vertical rods 13 are inserted into the base 1, and then the plug plate 1 14 is inserted back into the plug-in groove 2 11. At this time, the plurality of vertical rods 13 can be limited, ensuring that when personnel assemble the overall device, they do not need to use multiple bolts, which is convenient for personnel to carry out construction operations and save working time. At the same time, it is also convenient for personnel to fold, store and transport the overall device.
