The overall structure formed by these components and the light guide plate is the light guide assembly.

[0003] Although there are various current light guide assemblies, there are still certain problems. For example, most current light guide plates are equipped with multiple LEDs, which emit light upward to illuminate the instrument panel for display. The LEDs require wires, and these wires generally need to be fixed using buckles or adhesives, which is time-consuming and laborious during operation and seriously affects work efficiency.

[0009] Furthermore: a c-shaped support plate is arranged at the center of the supporting plate, and a wire passing cylinder is fixed at the center of the support plate, and the wire passes through the wire passing cylinder.

[0010] Furthermore: the overall structure formed by the rotating rod, the transmission rod, and the limiting claw is symmetrically arranged at least in a group on the supporting plate, and adjacent two limiting claws are arranged in a vertically staggered manner.

[0013] Further: The limiting claw is detachably connected to the transmission rod by screws, and at least two limiting claws are arranged on the transmission rod.
