By means of the rotation of one of the rotating shafts, the driving wheel drives the driven wheel and another rotating shaft to rotate. At the same time, the second lead screw and the third lead screw rotate, so that the first moving block and the second moving block drive the fixed plate to move up and down, thereby achieving the purpose of adjusting the goods to a suitable height. By the operation of the first motor, the first lead screw is driven to rotate, so that the moving cylinder pushes the push plate to move left and right, thereby achieving the purpose of pushing the goods onto the shelf.
