Top board（9）, pressure head（10）, transition tapered sleeve（11）And positioning seat（12）Composition；The top board（9）With guiding mechanism（8）Even
Connect, the pressure head（10）Upper end pass through pressure head contiguous block（13）With top board（9）It is fixedly connected, pressure head（10）Lower end pass through
Spring guiding mechanism（14）With transition tapered sleeve（11）Connection；The spring guiding mechanism（14）It is by left and right lead（15）And peace
Mounted in left and right lead（15）On spring（16）Composition, left and right lead（15）Upper end and pressure head contiguous block（13）Connection,
Lower end and transition tapered sleeve（11）Connection, spring（16）Installed in pressure head contiguous block（13）With transition tapered sleeve（11）Between left and right lead
Xiang Zhu（15）On；The positioning seat（12）It is fixedly mounted on bottom plate（17）On；During assembling, by the reinforced ball pivot in V ends（2）Or small end
Ball pivot（5）It is respectively put into V-type termination（4）Or small end termination（7）Endoporus in, and by the reinforced ball pivot in V ends（2）Or small end ball pivot
（5）Flat be put into the positioning seat of this special press-in device（12）In, by V ends check ring（3）With small end check ring（6）Put
Enter the transition tapered sleeve of this special press-in device（11）In, start special press-in device, top board（9）And pressure head（10）To moving down
It is dynamic, pressure head（10）By V ends check ring（3）Or small end check ring（6）Along transition tapered sleeve（11）Stepwize Shrink is to V-type termination
（4）Or small end termination（7）Hole size, pressure head（10）Continue to move downward, by V ends check ring（3）Or small end spring catch
Circle（6）V-type termination is depressed into respectively（4）Or small end termination（7）Groove position when, V ends check ring（3）Or small end check ring
（6）V-type termination is respectively charged into by its own resilient（4）Or small end termination（7）Neck in.
