Section is provided with the second external screw thread, and the second annular gasket pass is arranged on the second spiro rod section, and the second annular gasket pass is provided with
Second internal thread, the second internal thread of the second annular gasket pass and the second external screw thread of the second spiro rod section mutually coincide, the
Second ring pad pass is located in groove, the length of the second annular gasket pass and first annular pad bottleneck segment length phase
Together, the second external screw thread of the first internal thread of first annular pad pass and the second spiro rod section mutually coincide, the second air ring
Second internal thread of piece pass and the first external screw thread of the first spiro rod section mutually coincide.
The pad cover plate, first annular pad pass and the second annular gasket pass are by polytetrafluoroethylene (PTFE) structure
Into.
First spiro rod section and the second spiro rod section are polytetrafluoroethylene (PTFE) screw rod.
The utility model has the advantages that：Be rotated down first annular pad pass, make first annular pad pass and
First spiro rod section departs from；The second annular gasket pass is rotated up, makes the second annular gasket pass and the second spiro rod section phase
Mutually depart from, the second annular gasket pass taken out outside groove, first annular pad pass is rotated on the second spiro rod section,
First annular pad pass is accommodated in groove；Second annular gasket pass is rotated on the first spiro rod section, first
When be first annular pad pass outside spiro rod section, the pad is adapted to the less bottleneck of bore to use, and is the outside the first spiro rod section
During second ring pad pass, the pad is adapted to the larger bottleneck of bore to use.
