[0023] The narrow extraction guide bevel 1212 and the wide extraction guide bevel 1213 are both inclined structures rising from the inside to the outside facing the outside of the quick-insertion part 12, and the insertion guide bevel 1211 is an inclined structure rising from the outside to the inside facing the outside of the quick-insertion part 12.

[0024] The integrated heat dissipation headlamp housing 2 is composed of an end external threaded portion 21, a positioning and mounting portion 22, and a connector 23 connected between the end external threaded portion 21 and the positioning and mounting portion 22. A plurality of heat dissipation ribs 221 are arranged on the outer surface of the positioning and mounting portion 22. The LED headlamp assembly 3 is composed of a low-power LED lamp element 32, a circuit board element 33, and the power-on pin 31 in sequence from beginning to end. The low-power LED lamp element 32 is confined in the end external threaded portion 21, and the LED lamps on both sides of the low-power LED lamp element 32 are exposed on both sides of the connector 23.

[0026] In summary, the specific implementation of the present invention is as follows: first, the LED headlamp assembly 3 extends from the external threaded portion 21 of the end into the integrated heat dissipation headlamp housing 2 to ensure that all components are correctly aligned, wherein the low-power LED lamp element 32 of the LED headlamp assembly 3 is limitedly fixed in the external threaded portion 21 of the end, and the circuit board element 33 of the LED headlamp assembly 3 is fixed in the fixed structure composed of the positioning and mounting portion 22 and the glue sealing portion 11 of the insulating quick plug-in 1, and the power pin 31 connected to the tail of the circuit board element 33 is fixed by the quick plug-in 1.
