[0023] The cross-section of the hook rod 5 is J-shaped and is arranged flat.
[0024] The cross section of the end where the hook rod 5 fits the funnel 1 is an arc surface, so that the funnel 1 can push the hook rod 5 to slide.
[0025] Please combine Figure 1As shown, during use, when the length of the corrugated hose needs to be shortened, the staff presses down the sliding assembly, the sliding assembly drives the reset assembly to swing, the reset assembly drives the hook rod 5 to swing, and then releases the sliding assembly. At this time, the reset assembly drives multiple hook rods 5 to swing in multiple directions to push the steel ring on the corrugated hose to move, and repeatedly presses the sliding assembly. The sliding assembly indirectly drives the hook rod 5 to swing and pushes the steel ring on the corrugated hose to fold in sequence, thereby improving the flatness of the folding of the steel ring of the corrugated hose and reducing the internal cross-sectional area of the corrugated hose, thereby increasing the flow rate of the wind at the output end of the funnel and improving the dust reduction effect.
[0026] Please combine Figure 1 , Figure 2 As shown, an embodiment of a support assembly includes a plurality of support rods 3 annularly fixed to the side wall of a funnel 1 , a first circular ring 2 is fixedly connected between the plurality of support rods 3 , and the first circular ring 2 is sleeved on the funnel 1 .
[0027] The first ring 2 and the plurality of support rods 3 provide support during the rotation of the reset assembly.
[0028] Please combine Figure 1 , Figure 2 , Figure 3 As shown, an embodiment of a reset assembly comprises a plurality of barrel bodies 4 which are uniformly rotated in an annular manner on a first ring 2, a hook rod 5 is slidably arranged in the barrel body 4, a tension spring 6 is fixedly connected between the hook rod 5 and the barrel body 4, the tension spring 6 is arranged in the barrel body 4, limiting rings 7 are fitted on both sides of the barrel body 4, the limiting ring 7 is fixedly arranged on the first ring 2, and a torsion spring 8 is fixedly connected at the connection between the first ring 2 and the barrel body 4.
