[0035] With reference to Figures 1 to 4 Specifically, a placement area 210 is formed between the self-locking parts 300, when the material tray is placed, the material tray will abut against the limiting block 320 and make the limiting block 320 compressed back into the mounting seat 310 during the downward movement of the material tray, at this time, the limiting block 320 will not limit the material tray, so that the material tray can be placed in the placement area 210; after the material tray is placed, the elastic force of the elastic part 330 drives the limiting block 320 to extend out of the mounting seat 310 after the external force of the material tray abutting against the limiting block 320 disappears, and the limiting block 320 extends outwards above the material tray to limit the material tray from above. It can be understood that a plurality of self-locking parts 300 are arranged on both sides of the material supporting part 200, the limiting blocks 320 of the self-locking parts 300 are arranged towards the placement area 210, and the limiting blocks 320 of the plurality of self-locking parts 300 are compressed back at the same time when the material tray moves downward, and the plurality of limiting blocks 320 extend out at the same time to limit the material tray from both sides after the material tray is placed, the material tray is locked and fixed by the plurality of limiting blocks 320, and the limiting effect is improved.
