A gasket is located above the stress ring to further enhance the fastening effect and protect the connected components at the same time. The lower limit block is threadedly connected to the first bolt to limit the moving range of the nut, and the nut is threadedly connected to the second bolt. By adjusting the position of the nut, the final fastening and positioning of the fastener are achieved. During the assembly process, first, the first bolt and the second bolt are respectively passed through the connected components, and then the first bolt and the second bolt are connected by a threaded sleeve and preliminarily fixed. The positions of the first connecting rod and the second connecting rod are adjusted to adapt to the specific angles and positions of the connected components, which is achieved through the cooperation of the connecting shaft and the fixed block. The first connecting rod and the second connecting rod are pulled to adjust the relative positions of the first bolt and the second bolt to achieve precise fastening.
