One end of the connecting block 20 is rotatably disposed on the rotating shaft, and the connecting shaft passes through the other end of the connecting block 20. There are two connecting units 2, one of the connecting units 2 is disposed at the front side below the other connecting unit 2, and the vertical connecting line between the axes of the two rotating shafts and the axes of the two connecting shafts forms a parallelogram. Both connecting shafts pass through the fixing block 3 and are rotatably connected to the fixing block 3. The lower surface of the rear end of the fixing block 3 is provided with a fastening surface 30 for pressing the material tray 5. The material tray locking device further includes a self-locking device 4 for locking the fixing block 3 when the fastening surface 30 presses the material tray 5.
