Sliding rods 25 are staggeredly installed on the opposite surfaces of the two groups of second protective plates 22, and the sliding rods 25 are slidably connected to the placement plate 3. Specifically, after starting the cylinder 19, the movable cylinder 4 can be driven to slide on the inside of the movable groove, and at the same time, the two groups of first protective plates 8 can be driven to move up and down, and the scissor-type lifting structure 21 will also extend and retract accordingly, and have a blocking effect.

[0033] Working principle: Starting the motor 7 can drive the threaded rod 5 to rotate inside the movable cylinder 4, so that the adjustment plate 6 slides inside the adjustment groove, and then drives the first protective plate 8 and the second protective plate 22 on both sides to move closer or farther away. If the first closing plate 9 and the second closing plate 23 are in a closed state, the limit plate 24 will also slide inside the limit groove to cooperate in the extension and retraction operation. After the movable seat 20 approaches the fixed seat 15, the pull ring 14 is buckled to push the pull plate 12 and the pressure block 11, so that the first spring 13 retracts, and after the pressure block 11 is forced to enter the inside of the pressure groove, its slope surface and the slope surface of the reset plate 16 are pressed against each other, so that the reset plate 16 drives the second spring 17 to retract, and wait until the pressure block 11 completely enters the pressure groove. After turning to the side, the reset plate 16 pops out and abuts against one end of the pressure block 11 for fixation, achieving the effect of closing and protecting the loading port. Pulling the buckle 18 can drive the reset plate 16 to actively retract to the inside of the reset groove. After the reset plate 16 is away from one end of the pressure block 11, the resistance to the first spring 13 disappears, which drives the pulling plate 12 and the pressure block 11 to rebound and move away from the fixed seat 15. Then, the first closing plate 9 can be deflected in conjunction with the hinge to open the gap for loading and unloading. After starting the cylinder 19, the movable cylinder 4 can be driven to slide on the inside of the movable groove, and at the same time drive the two groups of first protective plates 8 to move up and down, and the scissor-type lifting structure 21 also extends and retracts accordingly, and has a blocking effect.
