The first housing 1 and the second housing 2 are hinged at one end and are detachably connected. The first housing 1 has a first connecting member 10 on its side, and the second housing 2 has a second connecting member 11 on its side, which is hinged to the first connecting member 10 via a pin. The pin passes through a through hole in both the first connecting member 10 and the second connecting member 11, allowing for 0-180° rotation between the housings. After unfolding, the housings maintain angular stability through gravity self-locking. Figure 2 As shown, the second housing 2 contains a battery compartment 6, which houses a battery 7. Battery 7 fixing blocks are located at both ends of the battery compartment 6, and the battery 7 is fixed between these fixing blocks. The second housing 2 also contains a PWM board 8 and three LEDs 9. A PCB board 4 is electrically connected to the battery 7, PWM board 8, and LEDs 9.
