The utility model discloses a spring-docking traction device comprising a front traction device and a rear traction device. The front traction device comprises a connecting hanging ring, a rotary traction arm, a spring rotation shaft and limit fixing blocks. The connecting hanging ring is arranged at the front end of the rotary traction arm, and the spring rotation shaft is arranged at the joints of the limit fixing blocks and the rotary traction arm. The rear traction device comprises a spring fixing hook, connectors and a base plate, the spring fixing hook is arranged among the connectors, and a spiral spring is arranged between the rear end of the spring fixing hook and the base plate. The spring-docking traction device is small in occupation space. During connection, the front traction device is levered to be level and is pushed to the rear traction device of a flat-bed trailer ahead; during demounting, a user only needs to step on the rotary traction arm or pull a rotary plate of the fixing hook open, so that connection between trailers can be cut off, and the spring-docking traction device is convenient to operate, high in reliability and long in service life.
