[0023] During implementation, the elastic force of the tensioning spring 53 inside the tensioning groove 51 pulls the pin rod 52 downward, which drives the pressing plate 55 to press the circuit board 2. When the pin rod 52 moves downward, it also drives the elastic buckle 54 to fix the inner shell 1 to the outer shell, thereby solving the problem that the existing flexible LED light source module needs to be fixed with bolts, and improving the work efficiency during the assembly of the flexible LED light source module.
