[0006] The drainage notch of the above-mentioned generator lubricating oil detection sampling tool is a rectangular notch.

[0007] The rear end of the above-mentioned generator lubricating oil detection sampling tool is penetrated by the rear end of the operating handle, and the drainage guide rod is a stainless steel circular tube.

[0008] The operating handle of the above-mentioned generator lubricating oil detection sampling tool is a cylindrical structure, and anti-slip texture is arranged on the outer surface thereof.

[0009] The utility model provides a generator lubricating oil detects sampling instrument, it can through screw plug screw into the generator's lubricating oil plug seat, through the front end of drainage guide rod top development generator lubricating oil self -sealing device spring, makes the lubricating oil in generator by the drainage guide rod's drainage aperture into the drainage guide rod's center hole, under the pressure effect in the generator, lubricating oil flows along the drainage guide rod center hole. It can be seen from this that the utility model cooperates through drainage guide rod, screw plug, sealing washer and operating handle, can make the lubricating oil in generator smoothly lead out, thereby reaches the purpose of avoiding oil splash, prevents the secondary pollution to sample.
