[0027] When the motor 32 is working, it drives the screw rod 33 to rotate, and the slide 35 slides along the slide rod 34. The displacement distance and displacement direction of the slide 35 are controlled by the rotation direction and number of rotations of the motor 32, so as to achieve precise adjustment of the position of the slide 35.

[0028] Among them, the slide 35 of the second linear drive module 3 is connected to the flame cutting gun 4 through a connecting frame 36. When the slide 35 of the second linear drive module 3 moves driven by the motor 32 of the second linear drive module 3, the slide 35 of the second linear drive module 3 drives the connecting frame 36, and the connecting frame 36 drives the flame cutting gun 4 to move synchronously.
