请参阅图1与图2，本申请的第一实施例提供了一种弦准装置100，包括调节组件10、调节杆20与连接件30。
请参阅图3，调节组件10包括外壳11、传动杆12以及与传动杆12啮合的传动轮13，外壳11内设有空腔111，空腔111容置传动杆12与传动轮13，沿传动轮13的轴向方向，外壳11的一侧设有凸出部113，凸出部113中部开设通孔1131，通孔1131与空腔111连通，且通孔1131的内壁设有内螺纹1132。
调节杆20，包括相对设置的第一端21与第二端22，第一端21可拆卸地连接传动轮13，第二端22设有安装孔221，安装孔221用于固定琴弦。
连接件30，套设于调节杆20上，连接件30的一端设有外螺纹31，外螺纹31与内螺纹1132配合。
本实施例的弦准装置100在安装时，将调节杆20第一端21插入调节组件10的传动轮13中，同时调节杆20第一端21部分套设于通孔1131内。再将调节组件10与调节杆20安装于弦乐器中琴头200的背面，再将连接件30从琴头 200正面旋入通孔1131，实现弦准装置100在琴头200的固定。使用时，将琴弦穿过安装孔221，通过旋转传动杆12带动传动轮13、进而带动调节杆20旋转的方式，将琴弦固定缠绕于第二端22，并调节琴弦的松紧。
于一实施例中，调节组件10还包括调节件14，调节件14具有相对设置的第三端141与第四端142，第三端141连接传动杆12。使用者可以夹持第四端142，并通过第四端142旋转调节件14，从而经由传动杆12、传动轮13最终将扭力传递至调节杆20，实现琴弦的调节。
于一实施例中，传动杆12朝向调节件14的一端设有连接部121，第三端141设有连接孔1411，连接部121插接于连接孔1411内，以实现传动杆12与调节件14的稳固连接。调节件14可以与传动杆12仿形配合，连接部121的截面为多边形，连接孔1411的截面与连接部121大致相同的多边形，连接部121插接至连接孔1411时，连接部121与连接孔1411之间可以设为过盈配合，从而提高连接强度。
于一实施例中，沿第三端141到第四端142的方向，调节件14的横截面积逐渐增大，呈现扁平的柄状，提高了使用者扭转调节件14的便利性。
于一实施例中，传动轮13开设有固定孔131，固定孔131容置第一端21，以提高调节杆20与传动轮13的连接强度。
于一实施例中，调节杆20第二端22开设有凹陷部222，安装孔221设于凹陷部222处，在使用时，琴弦穿出安装孔221，并通过环绕数圈的方式固定于第二端22，此时琴弦环绕设置于凹陷部222处，提高琴弦的固定的稳定性。
于一实施例中，连接件30开设有定位孔32，定位孔32设于连接件30远离外螺纹31的一端，当安装连接件30时，可以通过杆状工具抵持定位孔32的方式以旋转连接件30，用于将连接件30固定牢靠或者拆卸。本实施例中连接件30靠外一侧对称设有两个定位孔32，以平衡连接件30被抵持旋转时的受力。
请参阅图4，于一实施例中，传动杆12设有凸缘122，外壳11设有收容槽112，收容槽112连通空腔111，且收容槽112容置凸缘122。空腔111为与传动杆12和传动轮13形状大致相同的两个圆柱体结合，收容槽112为扁平的圆柱体，且直径大于空腔111中与传动杆12的所在空间，使得空腔111与收容槽112 交界处形成台阶面，台阶面抵持传动杆12的凸缘122，以确保传动杆12在外壳11内定位稳定，不发生偏移。
于一实施例中，外壳11包括定位板114，定位板114安装于外壳11背离凸出部113的一侧，用于固定传动轮13，使用时先将传动轮13置入空腔111，再将安装板装入，从而固定传动轮13的位置，避免发生偏移，从而影响调弦。
请参阅图5，一种弦乐器，包括琴头200、琴身(图未示)与琴弦(图未示)，还包括如上述实施例所述的弦准装置100，弦准装置100安装于琴头200上，琴弦穿出并固定于安装孔221。琴头200上开设有多个安装槽210，安装槽210容置外壳11的凸出部113。本实施例中凸出部113的外缘为正六边形，安装槽210的形状与凸出部113对应设置。
于一实施例中，琴头200还设有定位凹槽(图未示)，定位凹槽设置于安装槽210的周侧，外壳11上设有定位凸起(图未示)，定位凸起设置于凸出部113的周侧。定位凸起可插接于定位凹槽内，且与定位凹槽的形状相对应，定位凸起与定位凹槽可设为T型、L型、矩形等，提高辨识度的同时以进一步提高外壳11与琴头200的连接强度。
对于本领域技术人员而言，显然本申请不限于上述示范性实施例的细节，而且在不背离本申请的精神或基本特征的情况下，能够以其他的具体形式实现本申请。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的。
以上实施例仅用以说明本申请的技术方案而非限制，尽管参照较佳实施例对本申请进行了详细说明，本领域的普通技术人员应当理解，可以对本申请的技术方案进行修改或等同替换，而不脱离本申请技术方案的精神和范围。
