A firing box 2 is mounted above a support 1, and a movable door 5 is provided on the front surface of the firing box 2. A top-opening guide hood 3 is provided on the top of the firing box 2, and a smoke exhaust pipe 4 is provided on the side of the guide hood 3. The other three sides of the firing box 2 are open or grilled. A hanging rack is provided inside the firing box 2. The lower surface of the firing box 2 is bottomless, and a debris collection drawer 6 is provided below it. The debris collection drawer 6 is slidably connected to the support 1 on both sides. A safety recovery cart 7 with small wheels is provided below the debris collection drawer 6. The upper end of the safety recovery cart 7 is open and corresponds to the position where the debris is dumped from the debris collection drawer 6. Salt water or antifreeze can be placed inside the safety recovery cart 7; or a leaky or non-leaky collection bag can be placed inside the safety recovery cart 7, with salt water or antifreeze placed inside the collection bag, thus facilitating the collection of debris and duds after wetting them, making them easy to transport, and preventing secondary reignition.

[0021] Rollers 11 are provided on both sides and near the rear of the chip drawer 6, and horizontal guide rails 12 are provided on both sides of the bracket 1. The rollers 11 roll along the guide rails. The lower front surface of the chip drawer 6 is supported on the crossbeam of the bracket 1.

[0022] like Figure 2 and Figure 3 As shown, the hanging device structure is as follows: a rotating base 7 is provided inside the firing box 2, and a first rotating shaft 8 is movably connected to the center of the rotating base 7. A guide tube 9 is provided on the first rotating shaft 8. When the guide tube 9 rotates with the first rotating shaft 8 to the middle position of the firing box 2, the top of the guide tube 9 corresponds to the opening position of the guide shroud 3. A heat dissipation hole 14 is provided on the guide tube 9. A fireworks placement plate 13 is fixedly connected to the bottom of the rotating base 7. The fireworks placed on the fireworks placement plate 13 are located at the center of the firing box 2 and directly below the guide tube 9. A second rotating shaft 16 is coaxially fitted on the first rotating shaft 8. A horizontal small firecracker hanger 17 is provided on the second rotating shaft 16. The small firecracker hanger 17 is provided with positioning holes or positioning grooves 18. This structure can realize both fireworks and firecrackers. For those skilled in the art, other structures can be used to achieve this function.
