The design of second mandril is conducive to only need to adjust the first mandril when adjusting high pressure or low pressure, and fit dimension does not need to increase
Or the quantity of reduction gasket carrys out fit dimension, adjusts more convenient；
2, one end that the first mandril extends to inside accommodating chamber is connected with positioning head, and the second mandril extends to inside accommodating chamber
One end offer location hole, location hole design compatible with positioning head, when being conducive to the mandril size required for adjusting,
Location hole can be allowed to play the role of a guiding to positioning head, improve the precision of dimensional fits；
The utility model only needs to adjust the first mandril, match by the way that mandril is divided into part when adjusting high pressure or low pressure
Size is closed, the quantity for not needing to increase or decrease gasket carrys out fit dimension, improves the precision of dimensional fits, while improving life
Produce efficiency.
