A lighting mechanism is provided on one side of the OBD connector 2, including an LED light 3, a battery 4, and a switch 5. The LED light 3 is located on one side of the OBD connector 2, the battery 4 is installed inside the device body 1, and a protective cover 6 is installed on the outside of the OBD connector 2. The lighting mechanism and the switch 5 control the LED light 3, facilitating the installation and lighting of the device. The protective cover 6 protects the OBD connector 2 from damage during storage.
[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a mounting cylinder 7 is provided on one side of the OBD connector 2, and the LED light 3 is installed inside the mounting cylinder 7. A groove 16 is provided at the end of the device body 1 away from the OBD connector 2, and the switch 5 is installed inside the groove 16. A connector 17 is provided inside the groove 16. By setting the mounting cylinder 7, the LED light 3 can be focused forward to improve the lighting effect. The groove 16 can prevent accidental activation of the switch 5. An external data cable is connected through the connector 17.
[0031] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, a battery compartment 8 is provided on one side of the main body 1. The battery 4 is installed inside the battery compartment 8. A cover 10 is connected to the battery compartment 8 by screws 9. Anti-slip textures 11 are provided on the side wall of the main body 1 and the cover 10. A connecting groove 12 is provided at one end of the battery compartment 8. A threaded hole 13 is opened on the inner side of the connecting groove 12. A connecting block 14 that mates with the connecting groove 12 is fixedly connected to one end of the cover 10. A countersunk hole 15 is opened on the connecting block 14. By integrating the battery compartment 8 on one side of the main body 1, the battery 4 can be accommodated without the need for an additional lighting power supply. The cover 10 provides a consistent overall appearance and improves aesthetics. The anti-slip textures 11 on the side wall of the main body 1 and the cover 10 facilitate insertion by personnel. The screws 9 are used to connect the cover 10 through the threaded hole 13 and the countersunk hole 15 to prevent the battery from falling out.
[0032] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a U-shaped frame 18 is rotatably mounted on the outer side of the main body 1.
