Detailed description of the invention
Embodiment one:
As it is shown in figure 1, the outer end of the outer end cylinder barrel of cylinder barrel 1 is two stage steps shape, second level step
Being positioned at the inner side of first order step 4, the diameter of first order step 4 is less than second level stepped diameters i.e.
The diameter of cylinder barrel 1；Second level step is provided with external screw thread.Match with cylinder barrel outer end two stage steps shape
Closing, the endoporus of flange 2 is two stage steps shape, and second level inner bore of step is positioned at first order inner bore of step
Inner side, the matching form of the first order step 4 of first order inner bore of step and cylinder barrel closes, the second level
Inner bore of step closes with the matching form of cylinder barrel 1；Second level inner bore of step is provided with female thread.The first order
