[0039] A specific application of this embodiment is:

[0040] The first step: when using, first place the mechanism to the specified position, and then quickly install the throttle body to be tested on the two flanges 9 through the bolts 11. After the throttle body is installed, start the oil pump 20. The oil pump 20 can suck the oil in the oil tank 1 into the oil pipe 7.

[0042] The third step: after the test of the mechanism is completed, the high-pressure air pump 2 is started, and the high-pressure air pump 2 delivers compressed air to the intake pipe 5. The compressed air entering the intake pipe 5 then enters the connecting pipe 8 through the oil pipe 7. The compressed air entering the connecting pipe 8 then enters the oil tank 1. The compressed gas cleaning can quickly and efficiently remove the residues remaining in the mechanism, and the cleaning work can be completed in a short time, preventing the residual oil from forming grease, thereby ensuring that the circulating oil circuit in the mechanism can be used normally.
