[0002] A screw plug generally includes a nut and a screw, and is a part that uses a threaded connection to prevent liquid leakage. The oil drain plug is usually installed in the oil drain port of the oil tank to prevent oil leakage. In order to ensure the sealing, a rubber sealing ring is often installed between the nut of the screw plug and the oil drain port of the oil tank to further play a role in anti-seepage sealing.

[0003] At present, engines and other equipment are needed in some daily product experiments. At the same time, in order to avoid safety hazards in the experimental process, the engine oil temperature needs to be recorded and responded to to prevent excessive temperature from causing safety accidents. Therefore, additional threaded holes need to be processed on some oil pans for installing temperature sensors, which is very inconvenient and increases manufacturing costs, which is not conducive to mass production.
