The second housing 2 is located between the first housing 1 and the third housing 5, and the third housing 5 is fixedly connected to the second housing 2. The cable specifically means a connection cable for connecting the plurality of connection ports 51 to a device (for example, a notebook computer), and the cable has a connection port, such as a USB port, which can be extended out of the wire receiving space and can be connected to the device.

As shown in fig. 4 to 8, the first housing 1 has a first inner surface 11, a spiral chute 12 is provided on the first inner surface 11, and a groove 120 communicates with a leading end portion and/or a trailing end portion of the spiral chute 12. In the present embodiment, the leading end portion and the trailing end portion of the spiral chute 12 are each in communication with one groove 120. The spiral chute 12 is wound around the axis of the rotation by more than one turn, and 1.5 turns are shown in fig. 7; in other embodiments, it may not be limited to 1.5 turns, but may be 2, 3, or 4 turns, etc. As shown in fig. 8, the cross section of the spiral chute 12 along the radial/rotational axis is V-shaped; the groove 120 is a hemispherical groove having an arcuate, preferably semi-circular, cross-section along the radial/rotational axis. The depth of the groove 120 is greater than the depth of the helical chute 12.

As shown in fig. 4 to 6, the second housing 2 has a second inner surface 21, and the second inner surface 21 and the first inner surface 11 are disposed opposite to each other with a space therebetween. A take-up space 16 is formed between the first inner surface 11 and the second inner surface 12.

Specifically, the first inner surface 11 and the second inner surface 21 are entirely planar, and preferably perpendicular to the rotational axis.

Further, the cable winding device 110 further comprises an elastic member 22 for inserting the second portion of the bump 4 into the groove 120. The elastic member 22 is provided between the second housing 2 and the bracket 3, preferably using a compression spring. Further, as shown in fig. 6, the bracket 3 is rotatably disposed on the second housing 2, and has a free end 31 and a pivot end 33, the pivot end 33 is rotatably connected to the second housing 2 through a pivot 32, and an included angle greater than 0, for example, an included angle of 90 degrees is formed between the axis of the pivot 32 and the axis of rotation, and the pivot 2 may extend in the radial direction of the second housing 2.
