[0012] Preferably, the guide rod and the threaded rod are connected at an oblique angle.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This utility model provides a plastic-coated part on the bolt head of the bolt body, and the plastic-coated part has an installation ring groove for connecting the car headlight. In use, the plastic-coated part of the bolt head is snapped onto the car headlight through the installation ring groove, and then the threaded shank is passed through the mounting hole of the car sheet metal part. Then, the nut is used to lock the threaded shank to the threaded connection, and the car headlight is installed on the car sheet metal part. Through the plastic-coated part, it can be effectively snapped onto the car headlight, and the weight of the mounting bolt is reduced, which has a lightweight effect. In addition, the plastic-coated part and the car headlight are not easy to wear, reducing the occurrence of damage between the car headlight and the mounting bolt, and improving the connection stability and reliability of the car headlight.

[0015] 2. This utility model sets a sealing gasket between the bolt head and the threaded shank through a sealing ring groove, and seals the bolt body and the automotive sheet metal parts through the sealing gasket, thereby improving the sealing performance between the automotive headlights and the sheet metal parts.

[0016] 3. This utility model is equipped with a guide rod, and the guide rod and the threaded rod are connected at an oblique angle, which makes it easy to screw the end of the threaded rod into the nut for installation and use, avoids the nut being screwed into the threaded rod at an angle, prevents the nut and the threaded rod from engaging, and ensures the normal use of the mounting bolt.
