The outer thread of the screw rod 14 is connected to a moving block 16, and the moving block 16 is driven to move by the screw rod 14. The top of the moving block 16 is fixedly connected to a limiting disk 17, and the limiting disk 17 is fixedly connected to a limiting column 18 on the inner side, which is convenient for replacing the reel 21. Installation disks 19 are fixedly connected on both sides of the partition 2, and installation columns 20 are fixedly connected to the outside of the installation disk 19. Reels 21 are arranged outside the limiting column 18 and the installation column 20, and a plastic wrap roll is arranged on the reel 21.

[0033] Reference Figure 2The limiting component includes slots 7, two slots 7 are opened at the top of the box body 1, a slot 8 is arranged on the outside of the slot 7, the slot 8 is opened on the outside of the box body 1, a pressing block 5 is arranged in the slot 8, and the outside of the pressing block 5 is slidably connected to the inner wall of the slot 8. The limiting component can limit the tough spring piece 4 on the dustproof plate 3, so as to facilitate the opening and closing of the dustproof plate 3 and the inspection of the inside of the box body 1.

[0034] Reference Figure 2 , Figure 3 and Figure 4 , the two rotating rods 11 are fixedly connected to the outside with auxiliary rollers 12, which is convenient for pulling out the cling film. The end of the screw rod 14 on the outside is fixedly connected with a knob 15, and the knob 15 is arranged on the outside of the box body 1. The screw rod 14 is conveniently driven to rotate by the knob 15. The moving block 16 is arranged in the mounting groove 13, and the outside of the moving block 16 is slidably connected to the inner wall of the mounting groove 13, and the mounting groove 13 has a limiting effect on the moving block 16.

[0035] Working principle: When in use, pull out the cling film of the required length according to the need, then cut the cling film with the cutting blade 10 for use. When the cling film roll 21 needs to be replaced, squeeze the pressing blocks 5 on both sides of the box body 1 by hand to contract the tough spring plate 4, so that the end of the tough spring plate 4 is free from the restriction of the limit block 6, and the tough spring plate 4 is pulled out from the slot 7, so that the dust plate 3 can be opened, and then the knob 15 is turned to drive the screw rod 14 to rotate, and the screw rod 14 drives the moving block 16 to move in the installation groove 13, thereby driving the limit plate 17 and the limit column 18 to be pulled out from the roll 21, and the roll 21 can be taken out, and then a new cling film roll 21 is inserted into the installation column 20, and then reversed. Turn the knob 15 to drive the limit plate 17 and the limit column 18 to be inserted into the reel 21 to limit the reel 21. When closing the dustproof plate 3, cover the dustproof plate 3 on the box body 1, so that the tough spring piece 4 is inserted into the slot 7. The U-shaped tough spring piece 4 is squeezed and contracted by the limit block 6, and the pressing block 5 enters the slot 8. When the tough spring piece 4 completely enters the slot 7, the tough spring piece 4 is separated from the squeeze of the limit block 6, thereby resetting and stretching in the slot 7. The tough spring piece 4 is limited by the limit block 6. The box body 1 is divided into two spaces by the partition 2, and two cling film reels 21 of different sizes can be installed at the same time. The corresponding cling film is selected according to the required packaging size to avoid waste.
