[0002] At present, the oil pipe is an important component of the automobile engine. Its main function is to connect the gasoline pump and the engine fuel injector to provide fuel. Once the engine oil pipe fails or is damaged, it will affect the starting and ignition of the engine. In most cars, there is also a return oil pipe. After the fuel pump supplies fuel to the engine, the return oil pipe returns the excess fuel to the fuel tank through the return oil pipeline. At the same time, it can also return the excess gasoline vapor collected by the carbon canister to the fuel tank.

[0003] However, in the market, when the connector is inserted into the oil pipe interface, most of them will increase the complexity of connector installation in order to increase the sealing of the oil pipe. It needs to be screwed together and installed with tools, which makes the installation and removal of the connector very complicated and difficult to operate. Therefore, it is necessary to design a new technical solution to solve the problem so that the connector can be installed and removed quickly. Utility Model Content
