[0021] As a technical optimization solution of the utility model, Figure 1 As shown, there is a return spring 307 between the two connecting plates 304, and the limiting blocks 306 are fixedly connected to the connecting plates 304. The two ends of the return spring 307 are respectively sleeved on the outside of the two limiting blocks 306, so that under the action of the return spring 307, the clamping block 305 and the connecting block 301 can be clamped more tightly.

[0022] As a technical optimization solution of the utility model, Figure 2 As shown, the two inserting blocks 4 are symmetrically distributed about the middle of the bottom plate 1 , and the cross-section of the top of the inserting block 4 is a trapezoidal structure, so it can play a guiding role when the inserting block 4 is engaged with the backlight assembly 2 .
