The invention discloses a fastener suitable for a steel plate spring vehicle. The fastener comprises a shell fixedly connected between a secondary beam and a cross beam; a locking mechanism is arranged in the shell, a rocking arm is fixedly connected to the front end of the locking mechanism, a connecting rod is hinged to the tail end of the rocking arm, and the bottom end of the connecting rod is hinged to an installation base; and the installation base is fixed to a steel plate spring through a plurality of locking bolts. According to the fastener, locking is achieved through the rocking arm and the connecting rod; when the steel plate spring bears loads and is in the horizontal state, the connecting rod upwards moves to push the rocking arm to rotate around a rotating shaft, the rotating shaft drives the rocking arm to rotate so as to push a sliding block to leftwards move in a sliding groove, and the self-locking function at the tail end of the rotating shaft can be achieved; in addition, the fastener has the beneficial effects of being simple in structure, convenient to install and maintain, convenient to use, high in reliability, low in cost and the like; and the fastener is suitable for mass application and popularization.
