When the bellows needs to be connected to the power sheath during use, the traditional installation method relies on the connection method of bolts and nuts, which requires the operator to rotate multiple bolts one by one. This type of installation process not only relies on specific tools, but the installation process is not only time-consuming and labor-intensive, but also faces the same problem when disassembly is required. This traditional connection method has obvious deficiencies in efficiency, affecting the convenience of the overall operation. Utility Model Content

In addition, the addition of the conductive rubber layer is intended to eliminate static electricity, prevent static electricity accumulation, and reduce the risk of sparks, especially when transporting flammable media, which significantly improves safety. Finally, the internally sprayed polytetrafluoroethylene layer, with its extremely low friction coefficient, reduces the resistance to medium flow and improves flow efficiency, while maintaining the material's high chemical stability and corrosion resistance.
