Approaching channel is configured with guiding joint, the guiding joint include with the matched semicircle guide bushings of guide channel tail end, and with lead
Draw the guiding siphunculus of casing connection.
Further, the diameter of the guiding siphunculus is less than the radius of guide bushings, guides siphunculus one end and guide bushings
End face connection, the ripple connection structure for being cooperatively connected with plastic flexible pipe, ripple connection structure is arranged in the outer wall of the other end
Improve the connective stability of guiding joint and plastic flexible pipe.
Further, the guide channel tail end is semicircular structure, setting and semicircular structure cooperation in guide bushings
Semi-circular recesses.The conveniently accessible guide bushings of semi-circular recesses structure, and guide channel and guiding set can be improved to a certain extent
The connective stability and leakproofness of pipe.
To keep pipe sheath connecting tube and revoling tube joint face smooth, the tail end of the pipe sheath connecting tube opens up the shaft shoulder, rotation
Casing is socketed on pipe sheath connecting tube tail end and is positioned by the shaft shoulder, and pipe sheath connecting tube is identical as revoling tube outer diameter.
To dismount convenient for pipe sheath connecting tube and ureter sheath, pipe sheath connecting tube front end outer wall is provided with plum blossom ear shaped knot
Structure.
The advantages and effects of the present invention are:
1, pipe sheath connecting tube and water outlet connector handle are set as relatively turnable structure in device, are avoided that adjustment water outlet
Connector handle angle causes the problem of putting sheath shift in position.
2, the revoling tube of water outlet connector handle is socketed on pipe sheath connecting tube tail end, and joint face is provided with annular seal ring,
It can be in the fluid seepage for guaranteeing to avoid junction while rotation connection.
3, water outlet connector handle is provided with guide channel, effectively drawing to fluid can be achieved in guide channel in conjunction with guiding joint
It leads, avoids fluid from flowing to operating table influence and pollute.
