The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

A flexible pipeline connecting piece comprises a corrugated pipe 1, a connecting male head 2, a connecting female head 3 and a traction mechanism,

the two ends of the corrugated pipe 1 are respectively fixedly connected with a connecting male head 2 and a connecting female head 3, the connecting female head 3 is sleeved with a threaded sleeve 4, the inner wall of the threaded sleeve 4 and the outer wall of the connecting male head 2 are provided with corresponding threads, the free end of the connecting female head 3 is provided with a limiting flange 5 for preventing the threaded sleeve 4 from being separated from the connecting female head 3, the free end of the connecting male head 2 is provided with a sealing ring which is abutted against the limiting flange 5, the connecting male head 2 and the connecting female head 3 are used for being communicated with a water supply pipeline, the water supply pipeline is provided with the corresponding connecting female head 3 and the connecting male head 2, when in use, the connecting male head 2 is abutted against the limiting flange 5, the threaded sleeve 4 is connected with the threads of the connecting male head 2, and the sealing ring is tightly connected with the limiting flange 5 by utilizing the pressure generated by the threads, thereby completing the sealed communication of the pipeline,
