A rotating ring 3 is rotatably connected to the outside of the fixing ring 2. Four ropes 4 are fixedly connected to the inside of the rotating ring 3. A spring 5 is sleeved on the outside of each rope 4. A slide plate 6 is fixedly connected to the inside of the spring 5. A rod 7 is fixedly connected to the inside of the slide plate 6. The fixing ring 2 is used to connect and limit other parts. The rotating ring 3 encloses the fixing ring 2 and is connected to the ropes 4 for easy rotation. The ropes 4 are used to pull the slide plate 6. The spring 5 is used to allow the slide plate 6 to automatically return to its original position. The rod 7, limited by the fixing ring 2, can only move in a specified direction and will not move or wobble randomly. Its outer side is fixed... The fixed plate 6 is designed to prevent the insertion rod 7 from falling off due to exceeding its range of motion. The swivel ring 3 has anti-slip texture 14 on its outside to facilitate rotation and prevent slippage. The rope 4 is externally slidably connected to the inside of the fixed ring 2, and the inside of the rope 4 is fixedly connected to the outside of the plate 6, so that when the rope 4 moves, it can pull the plate 6 to move. The outside of the spring 5 is fixedly connected to the inner wall of the fixed ring 2 to keep the spring 5 stable. The outside of the plate 6 is slidably connected to the inner wall of the fixed ring 2, and the outside of the insertion rod 7 is slidably connected to the inside of the fixed ring 2. The fixed ring 2 simultaneously restricts the movement direction of the plate 6 and the insertion rod 7. The outside of the insertion rod 7 is slidably connected to the inside of the support column 1 to enable the support column 1 to be quickly assembled.

[0034] Reference Figure 1 - Figure 4 The limiting assembly includes a fixing block 8, which is externally slidably connected to the inner wall of the slot 17. A limiting seat 15 is fixedly connected to the top of the fixing block 8. Multiple springs 9 are fixedly connected inside the limiting seat 15. A baffle 10 is fixedly connected between the inner sides of the multiple springs 9 on the same side. A limiting block 11 is fixedly connected to the inner side of the baffle 10. A crossbeam 12 is slidably connected between the inner sides of the four limiting blocks 11. The fixing block 8 is used to connect to the limiting seat 15. The limiting seat 15 is used to connect and protect the internal parts. The springs 9 are used to push the baffle. 10 moves, and the limiting block 11 is used to push the crossbeam 12 so that the crossbeam 12 is at the central axis of the support column 1. The crossbeam 12 is used to support the bridge. The baffle 10 is externally slidably connected to the inner wall of the limiting seat 15, and the limiting block 11 is externally slidably connected to the inner wall of the limiting seat 15. The limiting seat 15 simultaneously restricts the movement direction of the baffle 10 and the limiting block 11.

The insert rod 7 is externally inserted into the inside of the fixing block 8 to fix the fixing block 8.

[0035] Working principle: When using this device, first connect multiple support columns 1 and limiting components. By rotating the rotating ring 3, the rope 4 pulls the sliding plate 6 to compress the spring 5, causing the insertion rod 7 to retract into the fixing ring 2. Then connect two support columns 1 end to end. At this time, release the rotating ring 3. Under the limitation of the fixing ring 2, the spring 5 will immediately push the sliding plate 6, pushing out the insertion rod 7 and inserting it into the support column 1, fixing the support column 1 and achieving quick assembly and disassembly. Similarly, install the limiting components. Then, use the hoisting equipment to lift the crossbeam 12 and place it on the limiting seat 15. As the crossbeam 12 descends, it pushes the limiting blocks 11 on both sides to squeeze the baffle 10. Relying on the reaction force of the spring 9 on the baffle 10, the crossbeam 12 is pushed towards the central axis of the support column 1, keeping the crossbeam 12 stable and preventing it from falling. At this time, the bridge can be built on the top of the crossbeam 12. The operation is convenient and labor-saving, and the assembly and disassembly are convenient.
