[0011] In order to facilitate electrical conduction, high-voltage lead pins are provided in the long steel card and the short steel card, and the high-voltage lead pins are connected to the damping wire.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model can be used to adjust the installation position of the spark plug of a domestic motorcycle engine from the left and right sides of the cylinder body to the middle or the inside, which greatly improves the appearance of the engine. At the same time, it can also solve the problem of compact or limited space of the off-road vehicle. Through the cooperation of the spark plug full rubber cap assembly and the high-voltage damping wire assembly, the relative pulling force between the high-voltage damping wire and the spark plug cap assembly is effectively improved to avoid the sliding of the high-voltage wire. It can also save time and effort to conveniently remove the spark plug cap and perform simple and convenient replacement, thereby solving the problem of difficult after-sales maintenance and the problem of safety and reliability in use.

[0014] 2. The long steel clip and short steel clip structure fit the spark plug more tightly than the spring structure used in existing motorcycle technology, and are not easy to loosen, which facilitates the rapid installation and removal of the spark plug, and improves product reliability. The setting of the high-voltage wire lead needle on the long steel clip and the threaded clip can effectively transfer the high voltage electricity generated at the high-voltage package body end to the spark plug through the high-voltage damping wire for discharge.
