Technical Problem
[0003]在习知结构中，该心轴具有一传动齿轮可滑动嵌入两蜗杆之一进行带动，或保持传动齿轮于两螺杆之间呈心轴空转的状态，由于心轴的滑动操作及转动是由调整钮施力进行的，在整个结构设计中并没有针对心轴位置予以定位的特别设计，所以在调整钮的操作过程中十分依赖使用者的手感，因此在习知双导线调整器调整的过程中，使用者虽然可以经由调整钮拉出或推入的操作确保心轴嵌入一蜗杆的穿孔中，并借由转动调整钮以收放该齿型卷线轮的导线，然而在转动调整钮的过程中难免会产生心轴相对蜗杆滑动的问题，致使心轴传动齿轮脱离蜗杆而造成空转的现象，不仅操作性不够稳定，更有许多使用者会误以为调整器已经损坏而保修，造成使用者与维修者双方极大的困扰
Benefits of technology
由于本实用新型的双导线调整器令线径C型扣呈可转动状态而设置在心轴的环槽内（即线径C型扣结合环槽呈间隙配合），且该线径C型扣的外径与两蜗杆的穿孔呈过盈配合，所以当线径C型扣的外径被穿孔轴向套入时，线径C型扣可经由弹性变形而径向收束，形成线径C型扣顶压在蜗杆穿孔内壁的状态，所以线径C型扣除了可受到心轴的带动而在蜗杆穿孔内滑动以外，当心轴进行转动时，线径C型扣与蜗杆穿孔间的固定作用，令心轴具有类似轴承的功能，让心轴的转动不会发生滑动，防止心轴传动齿轮脱离蜗杆而造成空转的现象，达到提升调整器操作稳定性的目的。

Abstract
The utility model relates to an improved structure of a double-conductor adjuster, the transmission gear of the mandrel of the adjuster is selectively slidably inserted into one of the two worms to drive the toothed winding wheel connected with the worm in which the transmission gear is inserted, so that the conductor combined or wound on the toothed winding wheel can be reeled in or out, the perforations of the mandrel and the two worms are in clearance fit, two ring grooves are provided on the mandrel, the two ring grooves are respectively located in the sliding range of the two worms, a wire diameter C-shaped buckle in a rotatable state is respectively arranged in the two ring grooves, the outer diameter of the wire diameter C-shaped buckle is in interference fit with the perforations of the two worms, the wire diameter C-shaped buckle of the mandrel is reeled in through elastic deformation and enters the worm perforation to generate a pressing force on the inner wall of the worm, so that the mandrel is prevented from sliding during rotation.
