[0014] 2. Ignite the fuse from the ignition hole. The fuse enters the inside of the expansion disk from the through hole on the top of the expansion disk. The heat generated by the burning fuse causes the expansion disk to expand. The edge of the expansion disk is inserted into the slot to complete the cover and fixation between the bottom plate and the top plate. When the expansion disk cools down, the middle of the expansion disk bulges upward to restore the initial shape. At this time, the bottom plate and the top plate can be separated by force.

[0015] 3. When setting off fireworks, the fireworks are ignited from the lead hole, and the fireworks at the fixed tube are set off. At this time, the fireworks generate heat, which causes the fixed tube to expand due to the heat, and the outer wall of the fixed tube pushes the block outward, so that the other end of the block is separated from the annular groove. Under the action of the spring force, the telescopic tube inside the fixed tube is pushed to insert into the fixed tube, so that the burned part of the fireworks is pushed out from the fixed tube. Similarly, when the fireworks burn into the telescopic tube, under the action of the heat of the fireworks, the annular groove of the next telescopic tube is separated from the block, and under the action of the spring force, the next telescopic tube is pushed into the previous telescopic tube, so that the fireworks burned in the previous telescopic tube are discharged. When the last telescopic tube is burned, the telescopic tube expands due to the heat, pushing the block connected with the slag discharge plate to move outward, and under the action of the spring force, the completely burned fireworks are discharged through the slag discharge plate, thereby realizing automatic slag discharge.

[0034] For further reference, Figure 3 and Figure 4 The interior of the chassis 1 is divided into three fan-shaped cavities by three partition plates 101. Three connecting tubes 102 are provided at the edge of the chassis 1. The connecting tubes 102 are hollow and penetrate the outer wall of the edge of the chassis 1. One end of the adjustment component 4 is frictionally connected to the outer end of the connecting tube 102.
