The sliding part 37 is a plate body, and a structure such as a slide rail 26 or a slide groove 28 is arranged at the bottom end, which can make the upper end of the wind tube 32 slide at its bottom end, thereby realizing the sliding connection between the wind tube 32 and the sliding part 37. Under normal circumstances, the length direction of the support plate 33 is parallel to the width direction of the steel belt 6. In this embodiment, the length direction of the sliding part 37 is set at an acute angle to the length direction of the steel belt 6 to realize the movement and adjustment of the position of the cutting machine 34.
