[0016] (1) When the utility model is used, the driving motor is started to move the entire active trolley group, and the sliding trolley group moves with the active trolley group. The slide rail can avoid the impact of wheel deviation when the trolley turns, and at the same time enhance the load-bearing capacity. Steering is achieved through plane bearings, and at the same time, the load-bearing capacity is enhanced. At the same time, since anti-collision strips are provided on the front and rear sides of the trolley frame, the minimum distance between the trolleys can be ensured when the barcode system fails, thereby preventing mechanical damage.
