[0002] The cylinder splitter wire is an indispensable part of the traditional ignition system. It is the medium through which the ignition coil transfers its energy to the spark plug. The cylinder splitter wire is also called the ignition wire. It distributes the ignition sequence and can transfer the high-voltage fire distributed by the distributor to the spark plug, so that the cylinder will ignite and burn to do work, and drive the engine to rotate. However, since a large amount of oil stains will be generated during use, it is very difficult to remove the spark plug connector after the oil stains solidify. Most of the time, tools are needed for auxiliary disassembly, which is very inconvenient and needs to be improved urgently. Utility Model Content

[0007] The utility model is further configured as follows: a tension spring is provided between the pair of pressing plates and the mounting sleeve, and two ends of the tension spring are respectively fixedly connected to the pair of pressing plates and the mounting sleeve.
[0008] By adopting the above technical solution, since tension springs are provided between the pair of pressing plates and the mounting sleeve, the two ends of the tension springs are respectively fixedly connected to the pair of pressing plates and the mounting sleeve, so that the pair of pressing plates can be tightly attached to the pair of movable rods under normal conditions.
[0009] A further configuration of the utility model is that one end of the booster ring is also provided with a circle of pressure plate for increasing the contact area between the booster ring and the cylinder.
[0010] By adopting the above technical solution, since one end of the booster ring is also provided with a circle of pressure plate for increasing the contact area with the cylinder, the force surface of the booster ring is further optimized, so that the spark plug connector can be pulled out more easily.
