[0028] The slider two 42 passes through the slotted opening 5 and extends to the outside.

[0029] The two slider twos 42 are threadedly connected to a bidirectional lead screw 44, and both ends of the bidirectional lead screw 44 are rotatably connected to the fixed bracket 1.

[0030] Embodiment 2

[0031] Compared with Embodiment 1, please refer to Figures 4-5As shown in the figure, the present utility model provides another implementation manner. Symmetrically fixed to the side wall of the mounting bracket 2 are U-shaped card seats 7. On both sides of the LED matrix lamp body 3, convex layers 8 are respectively formed by outward protrusions. When installing the LED matrix lamp body 3, press the pressing member 92 to slide the positioning post 93 into the sliding groove 91, align the convex layer 8 and insert it into the card seat 7, so that the positioning post 93 aligns with the positioning groove 95.
