And when the movable column 603 and the moving block 606 move together towards the toothed column 609, the moving block 606 contacts the speed reduction piece 612, so that the moving block 606 is slow in speed, namely the rotating speed of the cutter 7 is slow, and full cutting can be realized.

The plurality of plugging blocks 404 are all provided with vent holes 408, and the apertures of the plurality of vent holes 408 are arranged in a linear increasing trend from the side close to the external isolation sleeve 301 to the side far away from the external isolation sleeve 301.

Because high pressure is generated during the combustion of the flame, the flame can be removed by the vent hole 408 once contacting the blocking block 404 during the backflow of the flame, thereby avoiding the situation that the blocking block 404 is damaged by flushing.
