The cross-sectional area of ​​the through groove 8 at one end close to the placement groove 7 is smaller than the cross-sectional area of ​​the through groove 8 at one end away from the placement groove 7. The connecting block 10 is arranged in the through groove 8. A sealing ring 9 is arranged between the connecting block 10 and the through groove 8.
