When the bellows is clamped, the push plate 19 can be driven to move by the first cylinder 2, and the push plate 19 can be contacted with the side opposite to the bellows to push the bellows. When the end of the bellows away from the push plate 19 contacts the positioning component, the pushing of the bellows can be stopped, and then the bellows can be clamped and fixed by the fixing component, which helps to avoid shaking when the bellows is cut. The cutting assembly is movable, which is beneficial to maintaining the cutting quality of the corrugated tube. After the corrugated tube is fixed, the cutting assembly is driven to contact the corrugated tube by the second telescopic rod 11, so as to cut the corrugated tube. When the cutting assembly cuts the corrugated tube, waste chips may be generated. The vacuum cleaner 18 can generate suction, causing the waste chips to fall into the dust suction frame 33. The waste chips enter the dust collecting assembly through the dust suction frame 33, which can collect the waste chips. This helps to avoid the waste chips from splashing everywhere and is convenient for the staff to clean up later. Two inclined partitions are provided in the mounting frame 9 to prevent the waste chips from splashing and facilitate the waste chips to fall into the dust suction frame 33.
