[0033] Among them, the motor 31 can be a DC motor or an AC motor. The reducer connection bolt 33 corresponds to the connecting plate bolt hole 222 and the reducer threaded hole 323, and is used to rigidly connect the head connecting plate 22 of the rotating mechanism 3 and the lifting mechanism 2 into one body. The shaft sleeve 34 is used for axial positioning between the reducer 32 and the special-shaped multi-tube fireworks launcher 4 and reducing the friction between the two.

[0039] The working principle of the self-lifting and rotating special-shaped multi-tube fireworks setting off device is described in detail below.

[0040] like Figures 1-10 As shown, initially, the PLC controller 5 is in a power-off initial state, the lifting mechanism 2 is in a low position, and the rotating mechanism 3 is in a middle position. The fireworks 6 are inserted into the fireworks launch tube 41, and the bottom of the fireworks 6 is connected to one of the bundles of the electric ignition multi-beam lead wires 53. When the PLC controller 5 is powered on, the lifting control button is used to transmit motion instructions to the lifting mechanism 2 using the wire 1 51, and the lifting mechanism 2 drives the special-shaped multi-tube fireworks launch seat 4 to move up and down, thereby adjusting the launch height of the special-shaped multi-tube fireworks launch seat 4. After the lifting mechanism 2 reaches the target height, it is necessary to press the stop button to stop the lifting mechanism 2 from rising or falling and keep it at the required height position. When the PLC controller 5 is powered on, the wire 2 52 is used to transmit motion instructions to the rotating mechanism 3 through the rotating control button, and the motor 31 drives the reducer shaft 321 on the reducer 32 to rotate, thereby driving the special-shaped multi-tube fireworks launch seat 4 to rotate to a suitable angle. After the adjustment is completed, the electric ignition multi-beam lead wire 53 is used to transmit instructions to the special-shaped multi-tube fireworks launch seat 4, and the fireworks 6 achieve the firing effect.

[0041] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
