Control the piston rod of the cylinder 9 to push out or retract through the control panel 3, drive the mounting seat 12 at the lower end of the extension arm 11 to rise and fall. When the mounting seat 12 rises and falls, it slides on the guiding slide rail 7 through the slider 13 to improve the stability, realizing the adjustment of the ignition height of the high-energy igniter 22. At the same time, control the output shaft of the driving motor 15 to rotate through the control panel 3, and then drive the rotating shaft 16 to rotate automatically, realizing the adjustment of the position of the high-energy igniter 22, so that the high-energy igniter 22 is located at the furnace mouth. Then, control the electric push rod 20 to extend, drive the high-energy igniter 22 at the other end to move from the furnace mouth into the furnace. Finally, control the high-energy igniter 22 to start ignition through the control panel 3. After the ignition is completed, control the electric push rod 20 to retract through the control panel 3, drive the high-energy igniter 22 to leave the furnace. When it is necessary to disassemble, install and fix the high-energy igniter 22, place the high-energy igniter 22 on the anti-slip placement pad 29 in the U-shaped fixing seat 24. Hold the handwheel 27 and rotate the fastening bolt 26. After the fastening bolt 26 rotates through the nut seat 25, drive the lower anti-slip clamping plate 28 to move towards the high-energy igniter 22 until the anti-slip clamping plate 28 contacts the outer surface of the upper end of the high-energy igniter 22, and clamp and fix the high-energy igniter 22 on the anti-slip placement pad 29, completing the quick disassembly, installation and fixing of the high-energy igniter 22.
