Currently, some lamps typically incorporate a radiator or other heat dissipation structure within the housing to dissipate heat. However, existing technologies often prevent the heat from accumulating in the center of the radiator, making it difficult to escape. This hinders proper heat dissipation and can lead to uneven and inadequate heat dissipation. Summary of the Invention

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] After the heat is discharged, the heat dissipated in the heat sink by the hook portion is turned on, and the heat dissipation in the heat sink is stopped.

When the brake plate 162 moves in the second movable groove 134 to contact with the rotating wheel 169, it will drive the rotating wheel 169 to rotate. When the rotating wheel 169 rotates, it can respectively drive the first clamping plate 164 and the first clamping plate 165 to rotate. When the brake plate 162 moves downward to lose contact with the rotating wheel 169, the two sides of the brake plate 162 will contact the first clamping plate 164 and the first clamping plate 165 until the brake plate 162 moves to the slot notch. At this time, under the action of the second spring 168, the slot can clamp the brake plate 162, so that when the cover plate 130 is fixed to the radiator 400, the cover plate 130 will not be deformed due to uneven force.
