[0024] In the present utility model, during use, by pulling the handle 31, the two moving rods 27 move outwards on the vertical plate 26, causing the limiting plate 28 to move outwards beyond the range of the fixed cylinder 23. Then, the outer packaging roll 25 is sleeved on the rotating rod 24. After releasing the handle 31, the limiting plate 28 moves inwards under the elastic force of the second spring 29, making the limiting plate 28 in close contact with the outer packaging roll 25. When it is necessary to adjust the size of the folded outer packaging, by rotating the first handle 8 and the second handle 12, the first double-threaded screw rod 7 and the second double-threaded screw rod 11 are rotated, causing the two first threaded blocks 9 and the two second threaded blocks 13 to move. Furthermore, through the two first connecting blocks 10 and the two second connecting blocks 14, the four round rods 17 move on the disc 4, thus facilitating the adjustment of the size between the four round rods 17. Then, with the help of the length scale line 16, it is convenient to adjust to the appropriate size. After adjusting to the appropriate size, pull the pull block 22 to drive the pressing plate 20 to move outwards away from the round rod 17. Then, insert one end of the outer packaging roll 25 between the pressing plate 20 and the round rod 17. After releasing the pull block 22, the pressing plate 20 moves inwards under the elastic force of the first spring 21, fixing one end of the outer packaging roll 25 on the round rod 17. Then, start the motor 3 to drive the disc 4 to rotate on the bottom plate 1, causing the disc 4 to drive the four round rods 17 to rotate, thus facilitating the folding of the outer packaging roll 25 into a rectangular shape. Furthermore, it is convenient to quickly adjust the size of the folded outer packaging according to the size of the combined fireworks. The operation is simple and convenient, without consuming a large amount of physical strength and time, thereby improving the efficiency of folding the outer packaging.
