As shown in fig. 7 to 9, optionally, the fixing clamp 200 further includes a rubber layer 225, and the rubber layer 225 is attached along the inner wall of the third groove 224, so as to increase the friction between the third corrugated segment and the third groove 224 through the rubber layer 225, thereby further ensuring that the second corrugated segment 14 (the corrugated tube 100) does not slide. In addition, since the rubber layer 225 has certain elasticity and compressibility, when there is a deviation between the shape of the second bellows segment 14 (the corrugated tube 100) and the shape of the third groove 224, the rubber layer 225 can prevent the base 21 and the top cover from damaging the corrugated tube 100 during the folding process.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art.
