First driving mechanisms for making the upper moving blocks 6 and the lower moving blocks 7 approach each other are arranged on multiple fixed blocks 3. Driven mechanisms for making the two upper fastening plates 11 and the two lower fastening plates 12 approach each other while moving are arranged on the two upper moving blocks 6 and the two lower moving blocks 7 located in the same fixing groove.

[0029] It should be noted that during use, first place the two scaffolding vertical pipes 1 at the designated positions, and then adjust the scaffolding horizontal pipes 2 to the appropriate height through an external crane or manpower. After adjustment, align the fixed blocks 3 with the cross intersections of the scaffolding vertical pipes 1 and the scaffolding horizontal pipes 2 and make the scaffolding vertical pipes 1 and the scaffolding horizontal pipes 2 located between the upper fastening plates 11 and the lower fastening plates 12. Then, through the driving mechanism, move the two upper moving blocks 6 and the two lower moving blocks 7, so that the two upper fastening plates 11 and the two lower fastening plates 12 gradually approach the scaffolding horizontal pipes 2. At the same time, the movement of the two upper moving blocks 6 and the two lower moving blocks 7 will make the two upper fastening plates 11 and the two lower fastening plates 12 gradually approach the scaffolding horizontal pipes 2 through the driven mechanism, so that the first fastening grooves and the second fixing grooves respectively clamp the scaffolding vertical pipes 1 and the scaffolding horizontal pipes 2 at the same time, thereby fixing the scaffolding vertical pipes 1 and clamping and fixing the scaffolding horizontal pipes 2 at the same time, avoiding repeated fixing from different directions, reducing the working intensity and being convenient for use.

It can be understood that when the upper moving block 6 and the lower moving block 7 move, the first threaded rod 8 and the second threaded rod 9 will move. The movement of the first threaded rod 8 and the two second threaded rods 9 will drive the gear 13 to move. The movement of the gear 13 will rotate under the action of the rack 14. The rotation of the gear 13 will cause the first threaded rod 8 and the second threaded rod 9 to rotate. The rotation of the first threaded rod 8 and the second threaded rod 9 will cause the upper fastening plate 11 and the lower fastening plate 12 to approach the scaffolding vertical pipe 1.

[0039] The working principle of the above embodiment is as follows:

[0040] (1) During use, first place the two scaffolding risers 1 at the designated positions, and then use an external crane or manpower to adjust the scaffolding cross tube 2 to the appropriate height. After adjustment, align the fixing block 3 with the cross intersection of the scaffolding riser 1 and the scaffolding cross tube 2 and make the scaffolding riser 1 and the scaffolding cross tube 2 located between the upper fastening plate 11 and the lower fastening plate 12. Then rotate the fixing knob 5. The rotation of the fixing knob 5 drives the rotation of one of the positive and negative threaded rods 4. The rotation of one of the positive and negative threaded rods 4 will cause the rotation of the other positive and negative threaded rod 4 through the sprocket 16 and the chain 17. Under the action of the second guide rod 15, the rotation of the positive and negative threaded rod 4 will cause the movement of the two upper moving blocks 6 and the two lower moving blocks 7. The movement of the two upper moving blocks 6 and the two lower moving blocks 7 will respectively cause the two upper fastening plates 11 and the two lower fastening plates 12 to gradually approach the scaffolding cross tube 2. At the same time, the movement of the two upper moving blocks 6 and the two lower moving blocks 7 will drive the movement of the two first threaded rods 8 and the two second threaded rods 9. Under the action of the gear 13 and the rack 14, the movement of the two first threaded rods 8 and the two second threaded rods 9 will cause the rotation of the two first threaded rods 8 and the two second threaded rods 9. Under the action of the first guide rod 10, the rotation of the two first threaded rods 8 and the two second threaded rods 9 will respectively cause the two upper fastening plates 11 and the two lower fastening plates 12 to gradually approach the scaffolding cross tube 2, thereby enabling the first fastening groove and the second fixing groove to clamp the scaffolding riser 1 and the scaffolding cross tube 2 simultaneously, so as to fix the scaffolding riser 1 and clamp and fix the scaffolding cross tube 2 at the same time, avoiding repeated fixing from different directions, reducing the working intensity, and being convenient for use.

[0041] (2) When it is fixed, first rotate the fixing bolts 20 on the two horizontally corresponding inclined blocks 18 to release the fixation of the rotating plate 19. Then rotate the rotating plate 19 so that the orientations of the two movable blocks 21 correspond to each other. Then rotate the fixing bolts 20 again to fix the rotating plate 19. When it is fixed, place the two mounting blocks 22 equipped with the inclined main rod 24 and the inclined auxiliary rod 25 into the movable grooves on the two diagonally corresponding movable blocks 21 respectively, and then fix them with the mounting bolts 23. When it is fixed, fix the inclined auxiliary rod 25 with the limit bolt 26 to prevent the inclined auxiliary rod 25 from sliding, thereby playing a certain role in diagonal auxiliary support and making the scaffolding vertical pipe 1 and the scaffolding horizontal pipe 2 more stable and convenient to use.

[0042] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
