Three springs.
The beneficial effects of the utility model are：
1st, acted on simultaneously using recoil of spring power and bleed pressure, cylinder need to only provide 3*1200-3* in test process
500=2100N thrust can complete the reciprocation cycle test of spring, more conventional technology, and thrust reduces about 70%, only needs to use
Less cylinder and consume less source of the gas can normal work, so as to significantly save equipment making cost and use cost.
2nd, upper and lower two layers of springback power interaction during backhaul, reduces opening speed and impacts and reduce noise, extend
Cylinder service life.
