[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Example:

[0026] Reference Figure 1-4 A simple flame inoculation device includes a metal ring 1, on which three groups of empty holes 103 are arranged, and also includes: multiple groups of flame spray nozzles 101, which are fixedly connected in the metal ring 1 in an annular and inclined manner, and the gas outlet end of the flame spray nozzle 101 faces the center; three groups of legs 2, which are connected to the metal ring 1; two groups of plug rods 204, which are respectively fixedly connected to the two groups of legs 2, and the plug rods 204 are located in the empty holes 103; threaded holes 203 are opened on the other group of legs 2, and the threaded holes 203 are threadedly connected with a screw rod 301, and the screw rod 301 is fixedly connected with a knob 303, and the knob 303 is used to rotate the screw rod 301 to drive the metal ring 1 to move up and down on the plug rod 204 A connecting rod 302 is fixedly connected to the screw rod 301, and the knob 303 is connected to the connecting rod 302.
