The invention relates to a bolt-free fastener system for a tramcar. The bolt-free fastener system for the tramcar comprises e-type elastic strips, screw spikes and iron chairs. The iron chairs are laid on a sleeper. The screw spikes penetrate through the iron chairs and are fixedly connected to the sleeper. An iron base is arranged on each iron chair and provided with an installation hole used for installing the corresponding e-type elastic strip. One end of each e-type elastic strip penetrates through the corresponding installation hole and the other end of each e-type elastic strip is used for fixing a steel rail. The bolt-free fastener system for the tramcar is simple in structure; compared with a metro fastener, cost of a tramcar fastener is not increased, connectors can be omitted, regular and repeated screwing can be avoided, the distance-adjusting degree is effectively increased, stability is effectively improved, over-installation is effectively avoided, transverse-force-resistance is effectively improved, and prevention and protection are effectively achieved; the effect that the work is halved with double results can be achieved and three million times of fastener assembly fatigue tests show that results are good.
