If you want to improve the smoothness of the unwinding effect, you can also reinstall the lid 4 back to the opening of the accommodation bin 21 and lock it with screws, and then thread the handle 5 between the first connection hole 2c of the holding member 2 and the second connection hole 43 of the lid 4. Take the handle 5 as the rotating shaft and pull the decorative light string outwards to make the holding member 2, the main winding and unwinding member 1 and the auxiliary winding and unwinding member 3 rotate synchronously around the handle 5, and the decorative light string can be easily unwound.

[0040] When it is necessary to store the disassembled decorative light string, the cover 4 of the present utility model is in the removed state. The handle 5 is clamped on the corresponding bump 151 on the groove 15 of the main storage and release member 1 through the connecting groove 51. Then, after one end of the decorative light string is clamped on the clamping portion 34, the handle 5 is used to make the connecting section 12 of the main storage and release member 1 rotate around the accommodating section 2a of the holding member 2. At this time, due to the limiting relationship between the clamping block 33 of the auxiliary storage and release member 3 and the bayonet 13 of the main storage and release member 1, the auxiliary storage and release member 3 rotates together with the main storage and release member 1, and the decorative light string is wound around the connecting section 12 in the storage structure. Subsequently, the other end of the decorative light string is put into the accommodating bin 21 through the wire clamping port 24, the controller, the adapter and other structures are stored in the accommodating bin 21, and then other items to be stored (such as the handle 5, the remote control, etc.) are put into the storage bin together. Then, each second buckle 42 of the cover 4 is clamped in the corresponding card hole 23, and the installation hole 41 is locked and fixed at the fixing hole 22 with screws. Finally, the present utility model is placed at the storage position, and the storage of the decorative light string is completed. It should be noted that the design of the wire clamping port 24 can effectively prevent the decorative light string wound in the storage structure from loosening randomly, ensuring the storage effect of the decorative light string.
