[0006] By adopting the above technical solution, a flip cylinder is set to drive a spur rack, and the spur rack drives a gear and a flip wheel, so that the flip rod is finally rotated back and forth to realize the flipping of the suction nozzle in or out. By setting a fixed number of times, the flip mechanism can flip the suction nozzle back and forth to realize automated life testing; the clamping mechanism fixes the cup cover by setting a clamp and a fixing cylinder that match the cup cover to ensure that the cup cover is always in a stable state during the flipping process of the suction nozzle.

[0016] By adopting the above technical solution, by setting the flip-in limit block and the flip-out limit block to respectively cooperate with the flip-in limit pin and the flip-out limit pin to limit the position, it can ensure that the suction nozzle is flipped in or out accurately, avoiding mechanical damage to the suction nozzle caused by excessive flipping.
