与现有技术相比，本实用新型提供的一种可伸缩数据线，具有以下优点：
1.本实用新型实施例提供的可伸缩数据线，包括中空的壳体、线缆、卷线组件和活动组件，壳体界定一容置腔，卷线组件及活动组件设置于容置腔中，线缆缠绕卷线组件后穿过壳体外露；卷线组件包括卷线盘，卷线盘可相对壳体转动，活动组件设置在卷线盘的一侧且活动组件与壳体定位连接；活动组件包括与壳体和卷线盘配合的传动组件以及与壳体固定连接的辅助件，传动组件与卷线盘配合，辅助件设置于传动组件的一侧并与传动组件配合，卷线盘转动带动传动组件活动进而带动辅助件产生弹性形变以为传动组件提供朝向或远离辅助件的一侧摆动的预紧力。通过设置卷线盘，使得缠绕在卷线盘上的线缆可自由拉长或收缩。通过在可伸缩数据线中卷线盘与活动组件配合的方式，使得将缠绕与卷线盘上的线缆拉出任意长度时，活动组件均能够将线缆定位。当使用者要放线时，拉动线缆，带动卷线盘旋转即可使线缆从卷线盘上拉出，当使用者拉出合适的长度时，可直接松开线缆，卷线盘与活动组件中的传动组件以及辅助件配合使得线缆保持该长度以便于使用。可见，活动组件与卷线盘配合的设计简化了传动的可伸缩调节充电器的调节装置的结构，有效提高了可伸缩数据线的实用性。
2.本实用新型实施例提供的可伸缩数据线的传动组件包括运动齿轮、限位齿轮及摆动复位件，运动齿轮与卷线盘固定连接；摆动复位件设置于运动齿轮，限位齿轮以及辅助件之间，摆动复位件包括与限位齿轮配合的第一配合单元、与运动齿轮配合的第二配合单元以及与辅助件配合的第三配合单元，辅助件与第三配合单元配合为摆动复位件提供朝向或远离辅助件的一侧摆动的预紧力。通过辅助件的弹性形变通过第三配合单元对摆动复位件施加一个预紧力，使摆动复位件保持有向一侧摆动的趋势，而在拉动线缆带动卷线盘及运动齿轮转动时，运动齿轮会通过第二配合单元带动摆动复位件运动，从而使摆动复位件通过第一配合单元带动限位齿轮转动，但由于预紧力的存在，摆动复位件运动到一定距离时会发生回弹，从而跟限位齿轮的齿槽再次接触配合，通过与限位齿轮上不同的齿槽配合可实现卡位和收缩的功能。可见，由辅助件提供预紧力来使摆动复位件回弹的设计，使可伸缩数据线的结构更加简单。
3.本实用新型实施例提供的可伸缩数据线的辅助件为可产生弹性形变的条状复位件，条状复位件的一端与壳体固定连接，另一端与第三配合单元配合。通过与壳体定位连接，可保证在使用过程中条状复位件整体会保持相对静止，对摆动复位件提供一个稳定的预紧力，并且当辅助件设置为条状复位件时，辅助件本身就与传动组件实现了分体设置，当元件发生故障时，更容易实现更换。
4.本实用新型实施例提供的可伸缩数据线的条状复位件的一端间隔设置有至少两个槽或孔，壳体在对应位置设置有对应数量的限位轴，限位轴与条状复位上的槽或孔配合对条状复位件限位。至少两个轴孔定位配合可对条状复位件实现定位，使条状复位件与摆动复位件的配合更加稳定，且结构简单，安装方便，容易实现。
5.本实用新型实施例提供的可伸缩数据线的第一配合单元包括推动部与卡止部，推动部与卡止部分别设置在摆动复位件的两端与限位齿轮配合。推动部与卡止部的设计，可使摆动复位件在摆动中，对限位齿轮进行传动，与限位齿轮进行配合，从而实现限位齿轮对摆动复位件不同状态的卡止，结构简单，体积小巧，这样的设计使数据线整体更加轻便。
6.本实用新型实施例提供的可伸缩数据线的卷线组件还包括卷簧，卷簧设置在卷线盘远离活动组件的一侧且卷簧与卷线盘固定连接。卷簧可在线缆拉伸时储存弹性势能，在需要回收线缆时，通过储存的弹性势能实现回收，完善了数据线的可伸缩功能。
7.本实用新型实施例提供的可伸缩数据线的卷线组件还包括卷簧固定件，卷簧固定件与卷线盘靠近卷簧的一端定位连接，卷簧固定件的另一端与卷簧的一端卡接。通过卷簧固定件实现卷簧与卷线盘的固定连接，使安装更加方便，结构更加合理。
8.本实用新型实施例提供的可伸缩数据线的运动齿轮至少包括三个齿槽，第一配合单元为与齿槽配合的凸起。通过齿槽与凸起的配合，一方面可实现运动齿轮带动摆动复位件摆动，另一方面可使摆动复位件运动一定距离时，可从齿槽中滑出，通过预紧力实现回弹，至少三个齿槽可保证在运动齿轮转动时，摆动复位件不会长时间处于未与齿槽配合而静止的状态，从而避免了线缆不能及时卡止的情况。可见，摆动复位件的凸起与齿槽配合的设计，使可伸缩数据线的结构更加合 理，使用更加顺畅。
9.本实用新型实施例提供的可伸缩数据线的卷线盘靠近活动组件的一侧还设置有环形隔离壁，环形隔离壁与壳体界定一隔离腔，活动组件设置于隔离腔中。将活动组件通过隔离腔隔离开来，对活动组件起到了一定的保护作用，延长了可伸缩数据线的寿命。

请参阅图1，本实用新型第一实施例提供一种可伸缩数据线1，包括中空的壳体10、线缆11、卷线组件12和活动组件13。壳体10界定一容置腔，卷线组件12及活动组件13设置于容置腔中，线缆11缠绕卷线组件12后穿过壳体10 外露。卷线组件12包括卷线盘120，卷线盘120可相对壳体10转动，活动组件13设置在卷线盘120的一侧且活动组件13与壳体10定位连接，可以理解地，活动组件13与壳体10定位连接是指活动组件13通过与壳体10的连接，实现了活动组件13与壳体10之间的相对定位，但并不限制活动组件13在相对定位的位置上的运动。活动组件13包括与壳体10和卷线盘120配合的传动组件130以及与壳体10固定连接的辅助件131。传动组件130与卷线盘120配合，活动组件13可随卷线盘120转动而活动，辅助件131设置于传动组件130的一侧并与传动组件130配合，随传动组件130的活动而产生弹性形变。卷线盘120转动可带动传动组件130活动进而带动辅助件131产生弹性形变，以为传动组件130提供朝向或远离辅助件131的一侧摆动的预紧力。通过设置卷线盘120，使得缠绕在卷线盘120上的线缆11可自由拉长或收缩。通过在可伸缩数据线1中卷线盘120与活动组件13配合的方式，使得将缠绕与卷线盘120上的线缆11拉出任意长度时，活动组件13均能够将线缆11定位。当使用者要放线时，拉动线缆11，带动卷线盘120旋转即可使线缆11从卷线盘120上拉出，当使用者拉出合适的长度时，可直接松开线缆11，卷线盘120与活动组件13中的传动组件130以及辅助件131配合使得线缆11保持该长度以便于使用。可见，活动组件13与卷线盘120配合的设计简化了传动的可伸缩调节充电器的调节装置的结构，有效提高了可伸缩数据线1的实用性。
在一些实施例中，卷线组件12还包括卷簧121，卷簧121设置在卷线盘120远离活动组件13的一侧且卷簧121与卷线盘120固定连接。卷簧121可在线缆11拉伸时储存弹性势能，在需要回收线缆11时，通过储存的弹性势能实现回收，完善了数据线的可伸缩功能
请结合图1与图2，在一些实施例中，传动组件130包括运动齿轮1302、限位齿轮1301及摆动复位件1300。运动齿轮1302与卷线盘120固定连接，摆动复位件1300位于运动齿轮1302，限位齿轮1301和辅助件131之间，摆动复位件1300包括与限位齿轮1301配合的第一配合单元13000、与运动齿轮1302配合的第二配合单元13001以及与辅助件131配合的第三配合单元13002。其中，辅助件131与第三配合单元13002配合为摆动复位件1300提供朝向或远离辅助件131的一侧摆动的预紧力。
请结合图1至图3，在一些实施例中，运动齿轮1302至少包括三个齿槽，第二配合单元13001为与所述齿槽配合的凸起。通过齿槽与凸起的配合，一方面可实现运动齿轮1302带动摆动复位件1300摆动，另一方面可使摆动复位件1300运动一定距离时，可从齿槽中滑出，通过预紧力实现回弹，使其与下一个齿槽配合，至少三个齿槽可保证在运动齿轮1302转动时，摆动复位件1300不会长时间处于未与齿槽配合的状态，从而避免了线缆11不能及时卡止的情况。可见，凸块与齿槽配合的设计，使可伸缩数据线1的结构更加合理，使用更加顺畅。
请参阅图1至图4，在一些实施例中，限位齿轮1301上间隔设置有卡位齿槽13010和复位齿槽13011，第一配合单元13000包括推动部130000和卡止部130001，推动部130000和卡止部130001分别设置在摆动复位件1300的两端与限位齿轮1301的卡位齿槽13010和复位齿槽13011配合。
请结合图1至图5当拉伸线缆11时，运动齿轮1302通过第二配合单元13001带动摆动复位件1300摆动，使推动部130000与限位齿轮1301接触并推动限位齿轮1301转动，当拉伸停止时，由于卷簧121的弹力，会使卷线盘120回转一小段距离，此时卷线盘120的回转以及辅助件131提供的预紧力会带动摆动复位件1300回摆一段距离，此时摆动复位件1300的卡止部130001与限位齿轮1301的卡位齿槽13010配合，将摆动复位件1300固定到当前位置，从而使得与第二配合单元13001配合的运动齿轮1302固定到当前位置，进而实现卷线盘120以及线缆11的固定；当需要回收线缆11时，将线缆11拉伸合适的距离，运动齿轮1302带动摆动复位件1300摆动一段距离，使对推动部130000推动限位齿轮1301转动，将复位齿槽13011转到预定的位置，在松手时，由于运动齿轮1302的回转和预紧力的存在，摆动复位件1300回摆，卡止部130001与复位齿槽13011配合，此时第二配合单元13001不再与运动齿轮1302的齿槽配合，运动齿轮1302带动卷线盘120回转，完成线缆11的回收。
请参结合图5与图6，在一些实施例中，辅助件131为可产生弹性形变的条状复位件1310，条状复位件1310的一端为固定端与壳体10固定连接，另一端为自由端与摆动复位件1300配合。通过与壳体10固定连接，可保证在使用过程中条状复位件1310整体会保持相对静止，自由端在一定的范围内活动，对摆动复位件1300提供一个稳定的预紧力，并且当辅助件131设置为条状复位件1310时，辅助件131 本身就与传动组件130实现了分体设置，当元件发生故障时，更容易实现更换。
可以理解，预紧力的大小与自由端的长度而定，因此可以调整固定端与自由端的长度从而调整预紧力大大小。
请结合图1、图6与图8，在一些实施例中，条状复位件1310的一端间隔设置有至少两个槽或孔13100，壳体10在对应位置设置有对应数量的限位轴103，限位轴103与条状复位件1310上的槽或孔13100配合对条状复位件1310限位。至少两个轴孔定位配合可对条状复位件1310实现定位，使条状复位件1310与摆动复位件1300的配合更加稳定，且结构简单，安装方便，容易实现。
作为一种变形，条状装复位件与壳体10固定连接也可采用以下的方式：条状复位件1310的一端间隔设置有至少两个螺纹孔，壳体10的对应位置设置有对应数量的通孔，条状复位件1310与壳体10螺纹连接。螺纹连接的结构更加稳定，也同样结构简单，容易安装。
请参阅图7，在一些实施例中，第三配合单元13002为一凹槽，凹槽具有一定的深度，可保证摆动复位件1300在摆动时条状复位件1310不从凹槽中滑出。摆动复位件1300摆动时，凹槽与条状复位件1310相对运动，使条状复位件1310发生形变且使条状复位件1310的一端不滑出凹槽，从而提供一个稳定的预紧力。
请参阅图8，在一些实施例中，壳体10内设置有第一定位轴100与第二定位轴101，限位齿轮1301通过第一定位轴100与壳体10转动连接，摆动复位件1300通过第二定位轴101与壳体10转动连接。
请继续参阅图9，在一些实施例中，卷线组件12还包括卷簧固定件122，卷簧固定件122与卷线盘120靠近卷簧121的一端定位连接，卷簧固定件122的另一端与卷簧121的一端卡接。通过卷簧固定件122实现卷簧121与卷线盘120的固定连接，使安装更加方便，结构更加合理。
请结合图1与图10，在一些实施例中，卷线盘120靠近活动组件13的一侧还设置有环形隔离壁1200，环形隔离壁1200与壳体10界定一隔离腔，活动组件13设置于隔离腔中。将活动组件13通过隔离腔隔离开来，对活动组件13起到了一定的保护作用，延长了可伸缩数据线1的寿命。
请继续参阅图10，在一些实施例中，条状复位件1310设置为弧形，环绕中心轴102设置。环绕设置可以使得条状复位件1310由于形变而产生的预紧力能够更合理的反馈到摆动复位件1300上同时也使条状复位件1310与摆动复位件1300在相对运动时，两者不容易相互分离。
进一步地，线缆11还包括输入接头与输出接头。
可选的，线缆11的输入接头与输出接头均可为一个、两个或三个。具体的，在本实用新型实施例中，线缆11的输入接头为一个，输出接头为三个，且输入接头与任一输出接头可为USB接头、Type-C接头、Micro接头或Lightning接头。
示例性地，可伸缩数据线1的初始状态为回收状态，当需要使用数据线时，拉伸线缆11，线缆11的拉伸带动卷线盘120旋转，一方面，与卷线盘120固定连接的卷簧固定件122随着卷线盘120同步旋转，卷簧121弹力增大，另一方面，与卷线盘120固定连接的运动齿轮1302与卷线盘120同步旋转，带动与运动齿轮1302配合的摆动复位件1300向一侧转动，摆动复位件1300在转动时，推动部130000会推动限位齿轮1301转动，将卡位齿槽13010推动到预设位置，当摆动复位件1300摆动到一定距离时，摆动复位件1300上的第二配合单元13001从运动齿轮1302的齿槽中滑出，而此时与摆动复位件1300配合的条状复位件1310已发生了弹性形变，为摆动复位件1300提供了一个预紧力，因此摆动复位件1300朝着另一方向回弹，与运动齿轮1302的下一个齿槽配合，当拉到合适的长度松手后，卷簧121的弹力会使卷线盘120回转并带动运动齿轮1302回转，由于运动齿轮1302的回转以及预紧力的存在，使得摆动复位件1300上的卡止部130001与限位齿轮1301的卡位齿槽13010配合，将摆动复位件1300固定到当前位置，即使得与摆动复位件1300上第二配合单元13001配合运动齿轮1302固定到当前位置，从而实现卷线盘120以及线缆11的卡止；
当需要回收线缆11使，将线缆11拉伸一小段距离，使运动齿轮1302带动摆动复位件1300摆动一小段距离，使推动部130000推动限位齿轮1301，将复位齿槽13011推动到预设的位置，在松手时，摆动复位件1300回摆，使得卡止部130001与复位齿槽13011配合，将摆动复位件1300固定到当前位置，此时，摆动复位件1300的第二配合单元13001不再与运动齿轮1302配合，运动齿轮1302的回转不受阻碍，卷簧121的弹力使卷线盘120回转，完成线缆11的回收。
请结合图11和图12，在一些实施例中，传动组件130包括档位齿轮1303和摆动件1304，档位齿轮1303与卷线盘120固定连接，摆动件1304的一端与壳体转动连接；摆动件1304设置于档位齿轮1303与辅助件131之间，摆动件1304 的另一端设有档位齿轮1303配合的第四配合单元13040，摆动件1304还包括与辅助件131配合的第五配合单元13041，辅助件131与所述第五配合单元13041配合为摆动件1304提供朝向或远离所述辅助件131的一侧摆动的预紧力。
优选地，辅助件131为条状复位件1310，第四配合单元13040为设置在摆动件1304另一端的齿状凸块13042。
在一些实施例中，档位齿轮1303包括空档齿槽13030和限位齿槽13031，第四配合单元13040与空档齿槽13030与限位齿槽13031配合实现所述线缆11的回收与卡止。
可选地，空档齿槽13030的数量1～4，限位齿槽13031的数量为4～8。
优选地，空档齿槽13030的数量为2，限位齿槽13031数量为八个，且空档齿槽13030及限位齿槽13031在档位齿轮1303上对称设置。应理解，空档齿槽13030及限位齿槽13031的数量和设置位置还可以为其他方式，只要可实现线缆11拉伸时的卡止以及回收即可。
可以理解地，档位齿轮1303在使用过程中，会产生多档位循环的效果，即用户在拉伸线缆11时，每当拉伸一个大档位(摆动件1304从一个空档齿槽13030运动到下一个空档齿槽13030)，中间会有四个小档位进行微调(4个限位齿槽13031)，这样的设计既方便对线缆11长度的调节，同时也增强了用户的体验感。
可以理解地，在拉伸线缆11时，线缆11会带动卷线盘120以及档位齿轮1303转动，而档位齿轮1303会带动摆动件1304的一端向与辅助件131提供的预紧力方向相反的方向运动，当摆动件1304运动段行程后，会从档位齿轮1303的齿槽中脱离从而回弹，并与相邻的齿槽配合，而相邻的齿槽会继续带动摆动件1304向预紧力相反的方向摆动；
当拉伸动作停止后，此时若齿状凸块13042与限位齿槽13031配合，则档位齿轮1303会在回转一小段行程后，即线缆11会在回收一小段距离后，被摆动件1304卡止住，使得线缆11保持拉伸状态；若拉伸停止后，线缆11并未在回收一小段距离后卡止，则此时齿状凸块13042与空档齿槽13030配合，要实现线缆11的卡止只需继续拉伸线缆11，使得齿状凸块13042与限位齿槽13031配合即可；
当需要回收拉伸状态的线缆11时，继续拉伸线缆11直至齿状凸块13042与空档齿槽13030配合，此时松开线缆11，卷线盘120和档位齿轮1303回转，而空档齿槽13030会通过齿状凸块13042带动摆动件1304向预紧力方向摆动，使得档位齿轮1303在回转时，齿状凸块13042不再与限位齿槽13031配合，摆动件1304不再阻碍卷线盘120的回转，即线缆11的回收。
以上所述仅为本实用新型的较佳实施例而已，并不用以限制本实用新型，凡在本实用新型的原则之内所作的任何修改，等同替换和改进等均应包含本实用新型的保护范围之内。
