具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施方式作进一步地详细描述。
实施例1
如图1、图2所示为本发明的一个实施例，该实施例中卷线模组设置有转轮9，导线11或者信号线缠绕在转轮9上，与转轮9配合设置有止动按键4，与止动按键4配合有弹簧线5作为弹性支撑装置，在弹簧线5的弹力作用下止动按键4自动对转轮9进行阻止旋转，弹簧线5呈弧形，或者被止动按键4预压变形呈弧形。
止动按键4自动对转轮9进行阻止旋转，是阻止收回导线11时的旋转，对于释放导线11的旋转不能阻止，这是棘轮9-1和棘爪配合的结构要求。止动按键4可以采用金属按键。
如图3、图4所示，弹簧线5是单根簧线，根据弹力需要，也可以将单根簧线折叠形成并排的2根簧线，这样设计可以提高弹力，延长使用时间。弹簧线5的弧形也可以称作弓形，不预压时即呈弧形或者通过预压变形呈弧形均可，安装之后要保证弹簧线5对止动按键4形成足够的弹力支撑。
如图2、图4所示，卷线模组设置有固定盖6，转轮9安装在该固定盖6下方，止动按键4安装在该固定盖6一侧，固定盖6的盖体上设置有容纳槽，弹簧线5安装在该容纳槽内顶推止动按键4，驱使止动按键4对转轮9制动；容纳槽为弧形，弹簧线5两端弯曲构成配合部。
弹簧线5两端也可以不弯曲，不过弯曲后更容易和其他部件配合。
如图4、图5所示，弹簧线5基本上水平地安装在容纳槽中，即弧形径向与固定盖6平面平行，这样就能有效降低高度，占用空间较小。
止动按键4为杠杆结构，中部设置有安装孔，配合销钉2安装在固定盖6一侧，止动按键4围绕销钉2转动，止动按键4与转轮9配合的一端设置有棘爪，棘爪上安装有塑胶套3。在转轮9释放导线11旋转时，塑胶套3起到棘爪和转轮9之间的润滑作用。
转轮9上端安装有棘轮9-1，与止动按键4配合；转轮9中部设置有轴孔，固定盖6上固定有转轴1，转轮9围绕转轴1旋转，转轴1下端设置有卡环14，卡环14将转轮9限位在转轴1上。
如图2、图3、图6所示，转轮9上端设置有安装槽9-2，安装槽9-2中设置有电路连接弹片8，固定盖6下端面上设置有FPC连接端子7，电路连接弹片8一端与导线11连接，一端与FPC连接端子7连接，电路连接弹片8被转轮9带动相对FPC连接端子7旋转。
FPC连接端子7为圆环形，连接外部柔性电路板(即FPC)，电路连接弹片8为两片，对称布置分别和FPC连接端子7接触，转轮9通过电路连接弹片8对FPC连接端子7形成预压，这样就能充分保证电路连接的可靠性。FPC连接端子7和电路连接弹片8均要采用导电性能良好的材料制成，例如铜合金。
两片电路连接弹片8之间设置有导线17连接(与图7中的下连接端子8-2连接)，导线17会和导线11连接。
如图7所示，电路连接弹片8与FPC连接端子7接触的一端为叉式结构(图7中的上连接端子8-1)，并带有圆弧段，通过圆弧段与FPC连接端子7接触，这样能降低滑动时的摩擦力。
电路连接弹片8中部设置有固定孔8-3，相应地安装槽9-2中也设置有销柱与其配合，采用该设计，在电路连接弹片8相对FPC连接端子7旋转时可以更稳定。
转轮9下端设置有储能腔9-4，储能腔9-4中安装有卷簧12，卷簧12一端 与转轴1固定，一端与储能腔侧壁固定，随着导线11的拉出，转轮9旋转收紧卷簧12进行蓄能，为收回导线11提供预备动力。
储能腔9-4安装有转轮盖16。
转轮盖16的侧壁上设置有卡孔，储能腔9-4的侧壁上设置有卡爪9-5，储能腔9-4与转轮盖16卡接组合；转轮盖16的侧壁上在卡孔两侧设置有裂缝，允许该位置侧壁向外扩张变形适配卡爪9-5。
在卷线模组使用过程中，弹簧线5的下端与止动按键4的上端接触并保持弹簧线5一定量的预压，使止动按键4始终受弹簧线5沿力F的反方向推力，从而使塑胶套3保持卡入转轮9端部棘齿的趋势。
转轮9端面的棘齿与外轮廓切线间的夹角为左侧锐角、右侧直角设计，自然状态下，转轮9可沿B向顺时针转动，因塑胶套3的阻止，转轮9不能沿A向逆时针转动。
沿图3中C向拉动导线11，转轮9沿B向顺时针转动，卷簧12被反方向缠绕使转轮9产生沿A向逆时针转动的趋势，停止拉动导线11，在止动机构作用下，塑胶套3卡住转轮9端面棘齿而阻止转轮9沿A向逆时针转动；在止动按键4端部施加力F，塑胶套3向外运动脱离转轮9端面棘齿，转轮9在卷簧12作用下沿A向逆时针转动，导线11被收回到转轮线槽9-3里。
实施例2
该实施例是在实施例1的基础上对储能腔9-4做出进一步改进。如图1、图2所示，储能腔9-4安装有转轮盖16，转轮盖16中设置有密封圈15，轴孔中也设置有密封圈10，储能腔9-4中设置有阻尼脂，密封圈10、15防止阻尼脂泄露。
优选地，在储能腔9-4中设置转轴套13，转轴套13被卡环14限位，转轴套13上端压紧密封圈10，这样可以提高密封效果。密封圈15依靠储能腔9-4压紧。
设置阻尼脂能够调节卷簧的释放速度，让导线11缓慢收回，防止对导线11造成损伤。
实施例3
该实施例是在实施例1的基础上对电路连接弹片做出进一步改进。在该实施例中，电路连接弹片为1片(未图示)，实际上是将实施例1中的两片电路连接弹片8一体制成，其他结构如叉式结构相同，只不过是一体冲切制成，在中部和导线11连接。这样设计可以简化电路连接部分的组装工序。
以上所述，仅为本发明的具体实施方式，在本发明的上述教导下，本领域技术人员可以在上述实施例的基础上进行其他的改进或变形。本领域技术人员应该明白，上述的具体描述只是更好的解释本发明的目的，本发明的保护范围应以权利要求的保护范围为准。
