[0078] As shown in the figure, Figure 8As shown, in one embodiment, the distance L1 between the extension 222 and the through hole 121 in the first direction X is between 0.6cm and 10cm.

[0079] In this embodiment, the distance L1 between the extension section 222 and the through hole 121 in the first direction X is greater than 0.6 cm, so that the bending section 223 has a certain length, so that the stress distribution on the bending section 223 is uneven, thus avoiding stress concentration on the bending section 223 and reducing the guiding pressure of the guide part 13. This allows the guide part 13 to guide the bending section 223 so that the bending section 223 bends from the second direction Y to the first direction X.

[0080] Furthermore, this embodiment reduces the size of the telescopic cable module in the first direction X by making the distance L1 between the extension section 222 and the through hole 121 less than 10cm, which helps to reduce the volume of the telescopic cable module and makes it easier for users to carry the telescopic cable module.

At the same time, the first arc-shaped surface 131 can reduce the friction and resistance between the two, allowing the guide portion 13 to guide the bending segment 223 to bend more smoothly.

[0090] like Figure 5 As shown, in one embodiment, the top wall of the through hole 121 has a rounded corner structure 14. In this embodiment, by providing a rounded corner structure 14 on the top wall of the through hole 121, the friction and compression of the top wall of the through hole 121 on the data cable 2 is reduced when the interface 21 is driven to remove the data cable 2 from the receiving groove 12 under the action of external force, thereby reducing the possibility of damage to the data cable 2 and extending the service life of the data cable 2.

[0091] like Figure 5 , 7 As shown, in one embodiment, the opening 124 of the receiving groove has a rounded corner structure 14. By providing the rounded corner structure 14 at the opening 124 of the receiving groove in this embodiment, the presence of sharp edges at the opening 124 of the receiving groove is reduced, making the edge of the opening 124 of the receiving groove smoother and facilitating the insertion or removal of the user's fingers from the interface 21.

[0092] like Figure 7 , 9 As shown, in one embodiment, the length L3 of the receiving groove 12 is greater than the length L4 of the interface 21. The receiving groove 12 has a first sidewall 122 and a second sidewall 123 opposite to each other. The first sidewall 122 is provided with a through hole 121. The interface 21 is close to the first sidewall 122 so that an access space 125 is formed between the second sidewall 123 and the interface 21.

[0093] This embodiment provides a retrieval space 125 in the receiving slot 12, allowing users to easily grasp the interface 21 without having to forcefully clip or pull it. This improves the ease of use of the telescopic cable module and reduces the risk of damage due to improper operation.

[0094] In one embodiment, the length of the slot opening 124 is greater than the length of the interface 21.

[0095] like Figure 7As shown, in one embodiment, the second side wall 123 has a second arc surface 1231. This embodiment provides guiding assistance for the user to grab the interface 21 through the taking space 125, which facilitates the user to grab the interface 21.

[0096] This embodiment also provides a charging device comprising the flexible wire module facilitating interface storage as described in any of the above. This embodiment provides the charging device, which reduces the probability of the interface 21 being impacted and rubbed by the outside, can better protect the interface 21 from being damaged, helps to prolong the service life of the data line 2, and reduces the replacement demand caused by the damage of the interface 21.
