对上述进一步改进的实施例中，固定元件1包括内轴体15、及套设于内轴体15外径的外套筒16，旋转连接柱12一体加工成型在内轴体15，空腔11开设在外套筒16、并位于旋转连接柱12的外沿；固定结构13为开设在外套筒16并靠近内轴体15的固定卡槽，第一连接端32卡入至固定卡槽内；外套筒16开设有走线槽161，走线槽161贯穿于外套筒16，内轴体15居中贯通有通孔151，通孔151连通有通槽152，通槽152连通至走线槽161；通过固定卡槽配合第一连接端32卡入固定，使得蓄力元件3的一端固定连接在内部，在旋转时产生扭力作用，从而产生蓄力，回弹时具有助力作用；设置走线槽161、通孔151、和通槽152配合下，可用于连接线的走向，走线方便。
对上述进一步改进的实施例中，固定元件1的两端均设有空腔11，两端的空腔11内均设有旋转连接柱12，空腔11内设有蓄力元件3，旋转连接柱12连接有端盖2，采用两端对称设置，两端均设置有蓄力元件3、旋转连接柱12和端盖2，在使用中蓄力强度更高，稳定性更好。
对上述进一步改进的实施例中，旋转连接柱12套设有轴承121，端盖2设有旋转连接槽21，旋转连接槽21配合于轴承121，定位槽14位于旋转连接槽21的外沿，限位齿141一体成型在定位槽14内，通过旋转连接槽21配合轴承121的安装，从而方便结构旋转，旋转稳定。另外，限位齿141一体成型在定位槽14内，结构强度高，耐耗性强，限位效果好。
本发明在固定元件1内设置空腔11，并在空腔11内设置旋转连接柱12，旋转连接柱12连接端盖2，将空腔11封闭，将蓄力元件3置于内部，从而在使用中，通过转子组件和定子组件4配合，使得蓄力元件3配合限位齿141可用于限位，在正转时可通过限位面141b进行限位，反转时通过导向面141a进行导向旋转，保证结构的正常旋转和使用的蓄力。
以上实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
