The threaded column 406 rotates counterclockwise, and the connecting piece 407 moves backward. The clamping arm 409 is released. When the material needs to be restricted, the cylinder 509 pushes upward, driving the third connecting column 508 to move the fixed block 507 upward. The second connecting column 505 is fixed to the outer surface of the fixed block 507. The L-shaped plate 506 is slidably connected to the outer surface of the second connecting column 505. The fixed block 507 moves upward, causing the second connecting column 505 to move on the inner surface of the L-shaped plate 506, causing the second slider 503 to move along the direction of the second slide rail 501, thereby restricting the material in the working area. Otherwise, the cylinder 509 contracts downward to release the material.
