Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

Referring to fig. 1-4, a foot nail of an electric power transmission iron tower comprises a plurality of foot nails 1, one end of each foot nail 1 is fixedly connected with a u-shaped limiting plate 2 matched with an external iron tower, the inner side of each u-shaped limiting plate 2 is fixedly connected with a threaded rod 3 penetrating through the external iron tower, the threaded rod 3 is connected with a first hexagon nut 4 in a threaded manner, the first hexagon nut 4 abuts against the external iron tower, when the foot nail 1 is installed, the threaded rod 3 is inserted into a mounting hole reserved in the external iron tower, the external iron tower is clamped by the u-shaped limiting plates 2, the first hexagon nut 4 is rotated to be in threaded connection with the threaded rod 3 until the first hexagon nut 4 abuts against the external iron tower, and the phenomenon that the foot nail 1 is rotated when being trampled, the blockage of the foot nail 1 is lost, and a worker slides out of the foot nail 1 is avoided.
