Compared with prior art, the present invention has the following advantages：
(1) dismounting is efficient：After compressing pile without using press, then locking nut assembles pile.For making for instrument
With less, pile is fastened without using torque spanner, inflates fast insert-pull.
(2) it is at low cost：Without using expensive press, only need common gas decompression equipment can assembly operation.
(3) rotate efficient：For the fuel cell pack that multi-state is needed to test, it only need to simply pressurize and pile can be completed
Assembling.
(4) it is controllable to fill heap high-precision：Due to the use of pressure control pressing force, pile pressing force precision is high, simultaneously under
The speed of pressure can also be controlled effectively so that pile assembling is more controllable.
