[0032] By setting the universal wheel 67, when the staff controls the servo motor 66 to make the movable pallet 61 move along the surface of the connecting rod 62 at the end of the fixed pallet 60, the universal wheel 67 set at the bottom end of the movable pallet 61 rotates along the surface of the bottom plate 1, thereby improving the movement effect of the movable pallet 61, and the staff can limit the continued movement of the movable pallet 61 by locking the universal wheel 67, thereby adjusting the stability of the material support assembly 6.
