[0025] like Figure 2 , Figure 3 As shown, the inner wall of the bellows body 1 is fixedly connected with a plurality of second reinforcement blocks 16, and the second reinforcement blocks 16 are evenly laid on the inner wall of the bellows body 1. Through the arrangement of the second reinforcement blocks 16, the second reinforcement blocks 16 are strip-shaped rubber blocks, and the inner wall of the bellows body 1 can be reinforced against bending through the arrangement of the second reinforcement blocks 16.

[0026] like Figure 1 , Figure 4As shown, one end of the corrugated pipe body 1 is fixedly connected to a first connecting head 9, and the inner wall of the first connecting head 9 is fixedly connected to a first connecting inner tube 11. The first connecting head 9 and the first connecting inner tube 11 are both plastic tube type connecting heads, and the first connecting inner tube 11 is fixed on the first connecting head 9.

[0027] like Figure 1 , Figure 4 As shown, a first slot 10 is provided between the first connecting inner tube 11 and the first connecting head 9, and an insert 12 is fixedly connected to the outer surface of the first connecting inner tube 11. The insert 12 is a semicircular strip. A plurality of inserts 12 are arranged and are evenly arranged on the first connecting inner tube 11, and the inserts 12 are located in the first slot 10.

[0028] like Figure 1 , Figure 5 As shown, one end of the corrugated pipe body 1 away from the first connecting head 9 is fixedly connected to the second connecting head 8, and the inner wall of the second connecting head 8 is fixedly connected to the second connecting inner tube 14. The second connecting head 8 and the second connecting inner tube 14 are both plastic tube type connectors, and the second connecting inner tube 14 is fixed on the second connecting head 8.
