  • the width of the circular ring of the circular ring cylinder 4b is greater than the step height of the first step 14 and smaller than the width of the circular ring of the sealing ring 3. Since the width of the circular ring of the circular ring cylinder 4b is larger, the circular ring cylinder 4b provides a larger supporting area relative to the first step 14 and supports the sealing ring 3 more stably.
  • Embodiment 1 only lies in the structure of the support 4. The difference will be described in detail below, and other portions that are the same as those in Embodiment 1 will not be detailed any more here.
