[0002] A suspension bridge, also known as a hanging bridge, is a bridge with cables (or steel chains) suspended from towers and anchored on both sides (or both ends of the bridge) as the main load-bearing components of the superstructure. A suspension bridge is a bridge with cables or chains that bear tension as the main load-bearing components. It is composed of cables, towers, anchors, hangers, bridge deck systems and other parts. In the commonly used double-pull main cable structure, the main cable and the screw are connected by a double-pull anchor cup. When subjected to loads such as wind loads, earthquakes, and automobile braking forces, the anchor cup is prone to deflection, resulting in strong bending forces between the end of the main cable and the main body, affecting the life of the multiple strands of steel wires in the main cable.

[0025] It should be noted that if Figure 1 and Figure 2 As shown in FIG. 1 , in a commonly used double-pull rod main cable structure, the main cable and the screw are connected by a double-pull rod anchor cup. When subjected to loads such as wind load, earthquake impact, and automobile braking force, the anchor cup is prone to deflection, resulting in a strong bending force between the end of the main cable and the main body, which affects the life of the multiple strands of steel wires of the main cable. In this embodiment, as shown in FIG. Figure 3 As shown, the connecting plate 2 and the anchor cup 3 are separately arranged, and the connecting screw pair 4 is connected to the main cable 1 through the connecting plate 2. The anchor cup 3 is arranged between the two connecting screw pairs 4, which is sleeved on the end of the main cable 1 and contacts with the connecting plate 2 to form a spherical pair 5, so that when subjected to loads such as earthquakes, wind forces and braking forces, the anchor cup 3, the connecting plate 2 and the connecting screw pair 4 bear the load separately, avoiding a large bending force between the end of the main cable 1 and the main body, and protecting the steel wire of the main cable 1;
