[0027] As shown in the figure, Figure 3 The strong pressure assembly comprises a semicircular groove 8 symmetrically arranged between the limiting ring sleeve 4 and the connecting sleeve 6, a pressure protrusion 9 arranged on the limiting ring sleeve 4 and a pressure spring 10 connected between the pressure protrusion 9 and the side wall of the semicircular groove 8 of the connecting sleeve 6, the semicircular groove 8 on the limiting ring sleeve 4 and the connecting sleeve 6 forms an arc-shaped channel, the pressure protrusion 9 is arranged in the middle of the semicircular groove 8, the pressure spring 10 is arranged on both sides of the pressure protrusion 9, and the pressure spring 10 is arranged in the arc-shaped channel.

[0030] Working principle:

[0031] In the free state, the cleaning pipe body 1 is bent, so that the sliding seat sleeve 3 of the previous sleeve assembly can rotate by a certain angle in the connecting sleeve 6 of the adjacent sleeve assembly, the return spring 5 is abutted between the connecting sleeve 6 and the sliding seat sleeve 3, the end of the sliding seat sleeve 3 rotating by a certain angle forms a displacement difference, so as to extrude and shrink the return spring 5, until the abutting ring 11 of the connecting sleeve 6 and the limiting ring sleeve 4 abut each other, this position is the bending limiting position of the cleaning pipe body 1, so that the cleaning pipe body 1 is prevented from being excessively bent in the free state, and the return spring 5 that is shrunk can reversely push the end face of the sliding seat sleeve 3 to reset, so that the cleaning pipe body 1 returns to the vertical state.

[0032] When the space in the pipeline is narrow and the bending angle exceeds the maximum bending limiting angle of the cleaning pipe body 1, the cleaning pipe body 1 will be extruded with the inner wall of the pipeline under the action of the jet flow, when the pressure reaches a certain value, the outer convex part 123 of the abutting limiting ring sleeve 4 and the side wall part 122 of the connecting sleeve 6 will be mutually slipped, so that the limiting ring sleeve 4 rotates in the circumferential direction on the sliding seat sleeve 3, and in the rotating process, the bending angle of the limiting ring sleeve 4 can be increased through the change of the position of the inclined surface part, so that the limiting ring sleeve 4 can temporarily exceed the bending radius of the extra-high pressure cleaning pipe, and after passing through the bending part, the pressure spring 10 quickly pushes the limiting ring sleeve 4 to reversely rotate on the connecting sleeve 6 and quickly resets.
