Telescopic wiring device and sorting vehicle coupling system

The utility model relates to a telescopic wiring device and sorting vehicle coupling system which comprises a telescopic frame, and connecting pieces are arranged at the two ends of the telescopic frame. At least one side face of the telescopic frame is provided with first fixing frames used for fixing wire harnesses in an up-down staggered mode, and the first fixing frames are relatively close toor far away from the telescopic frame along with stretching and retracting of the telescopic frame. And after the distance between the trolleys is increased and reduced, the wire harness stably and safely reaches the corresponding extending and retracting length. 本实用新型涉及一种可伸缩走线装置和分拣车联挂系统，包括伸缩框,所述伸缩框的两端均设置连接件；所述伸缩框的至少一个侧面上下错位设置有用于固定线束的第一固定架，且所述第一固定架随伸缩框的伸缩相对靠近或远离。保证小车间距变大及缩小后，线束稳定安全的达到相应的伸出及收回长度。
