Traditional basket-style scaffolding typically uses fixed tie rods for support, but this design presents several challenges. For example, after prolonged use, the tie rods are prone to deformation and breakage. Furthermore, the large number of tie rods necessitates frequent maintenance and replacement, increasing maintenance costs. Furthermore, relying solely on tie rods is not a reliable method for safety. Utility Model Content

[0038] See also Figure 4 Two sets of embedded controls 3 are embedded in the first floor layer 100, and each set of embedded controls 3 includes multiple plastic embedded parts.
