Material carrier frame

The utility model provides a feed-holding shelf, compromising a feed-holding table, a first underlay, a flexible element, a first pipelike device, a second underlay, a second pipelike device and a soleplate. The feed-holding table, the first underlay and the first pipelike device are fixedly connected with each other in turn, the second underlay, the second pipelike device and the soleplate are fixedly connected with each other in turn, the flexible element is sleeved and connected on the first pipelike device, and the bottom of the first pipelike device is inserted in the second pipelike device through the second underlay and is shifted up and down related to the second pipelike. While the feed-holding shelf is used, the altitude can be changed according to the moving trend of feed slice supported by the feed-holding table, based on the flexibility of the flexible element, then the feed warp phenomenon resulting form the feed-holding table altitude can be prevented, two demands to make the in and out feed and soft feed-holding convenient can be satisfied, and the structure is simple and the performance is credible.
