The utility model relates to a lengthened-wind-plate inner-liner hold hoop used for fixing optical-cable leading-down iron pipes. A hoop plate part is formed by fitting and connection of a left half hold hoop and a right half hold hoop so as to fix a steel pipe framework. Both of the left and right half hold hoops are semicircles, and the two ends of each semicircle are bent outwards so that an installation lug is formed at each end. One side is extended so that a lengthened wing plate is formed. The half hold hoops and bolts are combined and installed on the side of the lengthened wing plate so that leading-down iron pipe hoop plates are formed. Liners are installed in both of the hold hoops. Through the hold hoop device, the optical-cable leading-down iron pipes can be effectively fixed; and the hold hoop device is safe, reliable and long in service life at the same time; PVC waterproof-material liners are installed at the inner sides of the hoop plates so as to prevent that in a hold hoop installation process, the steel pipe framework is collided so that a galvanized paint of the steel pipe framework falls off and the service life of the steel pipe framework is affected. The lengthened-wind-plate inner-liner hold hoop is simple in structure, convenient to manufacture, and suitable for large-scale popularization and use.
