When the plug block 4 is stuck in the interior of the connection box 1, the fixing frame 2 is fixed. When disassembly is required, the button 9 is pressed to drive the plug block 4 to slide into the interior of the fixing frame 2 to release the fixation. When the button 9 is released, the second spring 10 will bounce the limit plate 8. When the limit plate 8 is bounced, it drives the button 9 to reset, thereby facilitating the LED module The block is maintained and replaced. When the wiring harness is fixed, the connector 17 is inserted into the connecting block 12. At this time, the rotating block 14 is pressed. When the rotating block 14 is pressed, it will rotate inside the fixing plate 13. When the rotating block 14 rotates, the fixing block 16 is lifted. When the connector 17 is inserted into place, the rotating block 14 is released. At this time, the third spring 15 will bounce the rotating block 14. When the rotating block 14 is bounced, it drives the fixing block 16 to be inserted into the fixing groove 18 for fixing, thereby solving the problem that the connecting line 11 may be loose or in poor contact, and greatly improving the stability during connection.
