[0025] Insert the two ends of the supporting crossbeam 3 into the crossbeam insertion grooves 5 on the two connecting blocks 2 respectively, and then rotate the rotating block 34, which drives the bidirectional screw rod 33 to rotate. Since the two ends of the bidirectional screw rod 33 are respectively threadedly connected with the two second connecting plates 32, the two second connecting plates 32 move toward the direction close to the connecting block 2 as the bidirectional screw rod 33 rotates, and the second connecting plate 32 drives the second plug-in plate 29 and the second tooth block 30 to move toward the direction close to the crossbeam insertion groove 5, and one end of the second tooth block 30 will be inserted into the limit position on the crossbeam insertion groove 5 The tooth groove 31 is inside, so that the support beam 3 and the connecting block 2 can be limited and connected.
