Wedge block is provided in the square groove of back taper slot lower part, the thin rear end in elastic card front end is thick, elastic card front end be inclined-plane and
Lower cavity is formed with wedge block, elastic card rear end forms upper plenum with wedge block, and through-hole is communicated with upper plenum.It is square groove, trapezoidal
The setting of slot can so that elastic card is that there is more preferable card to set for one when being caught in back taper slot, the other is elastic card for convenience
It can deviate from from back taper slot.It is when the inclined-plane setting of elastic card front end can make elastic card be inserted into back taper slot and wedge-shaped
Block forms lower cavity and upper plenum, so that the front end of elastic card has part to be in contact with wedge block, due to the bullet of elastic card
Property effect so that the front end of elastic card is close to wedge block, is provided as using to play card.The upper plenum and through-hole being formed simultaneously
It communicates, and since the front end of elastic card is inclined-plane, causes the front end of elastic card with wedge block to be that part is connect, so when there is tool
When entering upper plenum and elastic card from through-hole and contacting, elastic card can be stirred with smaller power and is detached from wedge block,
To facilitate elastic card to deviate from from back taper slot.
Preferred embodiment is that the upper end of the cavity is provided with annular groove.After annular groove is for the assembly of quick assembling gas nozzle,
In stealth mode and protection mode, dust and water will not enter joint surface.
The beneficial effects of the invention are as follows：Vacuum pump jointing Quick replacing structure is implemented flexibly, and the period is short, to production
Product carry out modularization, simple and reliable, and sealing performance is high, easy to assembly, is welded and is assembled without professional equipment.
