Cord pinning clip suitable for steel cords of engineering tire

A cord pinning clip suitable for steel cords of an engineering tire is of a symmetrical elastic structure wound by bar-shaped metal materials. The cord pinning clip suitable for the steel cords of the engineering tire comprises a cord clip and a fixing plug pin, and is characterized in that the cord clip is provided with a semicircle sunken structure, and the fixing plug pin is of a structure expanding outwards relative to the two sides of the cord clip. According to the cord pinning clip suitable for the steel cords of the engineering tire, due to the fact that the cord clip is provided with the semicircle sunken structure, the fixing plug pin is of the structure expanding outwards relative to the two sides of the cord clip, when the cord pinning clip is used, the fixing plug pin can be put into the turned edge of the edge of a spool, the cord pinning clip is fixed on the spool by using the fixing plug pin, and meanwhile the end sockets of the steel cords are fixed in the semicircle sunken structure of the c
