具体实施方式
为了更充分理解本发明的技术内容，下面结合具体实施例对本发明的技术方案进一步介绍和说明，但不局限于此。
如图1-2A所示，本发明 双向可分离式传动联接的手柄 40 ，包括 与杆体 10 旋转联接的手柄本体 41 ，杆体 10 还包括与其头部螺纹联接的螺母 13 ，杆体 10 的尾部设有卡接槽 11 ；杆体 10 还设有轴向延伸的止转槽 12 ；螺母 13 位于手柄本体 40 内，且其外周设有环向齿状部 131 。 在联接时，杆体10因为设有止转槽12而不会转动，可以通过手柄40旋转螺母13，从而实现联接杆对工件之间的锁紧联接。
手柄40还包括与杆体10旋转联接的手柄本体41；手柄本体41设有空腔42，空腔42内设有铰接于手柄本体41的双向调节柄43；双向调节柄43设有铰接孔431（通过铰接螺钉44固定于手柄本体41内），及对称设于铰接孔431两侧的逆向啮合部432和顺向啮合部433；顺向啮合部433向外侧延伸至手柄本体41之外的拔动部434。其中的环向齿状部、逆向啮合部432和顺向啮合部433采用三角形齿。当触动拔动部434至不同的位置时，可以让手柄顺向或逆向推动螺母，从而使螺母的旋紧或旋松，可以在狭小的空间时，实现组合式联接杆对工件之间的锁紧联接。比如用于固定显示屏的多个箱体。由于双向调节柄需要保持在顺向啮合或逆向啮合的状态，因此，在铰接孔431的侧边设有棱边439，在手柄本体41上还固定有预紧座45，在预紧座45内依次设有预紧限位球450、预紧弹簧451和调节螺钉452。在在手柄本体41上还设有对应于调节螺钉452的调节孔411，以实现对预紧力的调节。由于双向调节柄的支撑点在铰接孔处，当逆向啮合部432处于啮合状态，只能逆向传递手柄上的扭力，反向时，会形成分解力，从而让逆向啮合部432处于脱离状态；当顺向啮合部433处于啮合状态，只能顺向传递手柄上的扭力，反向时，会形成分解力，从而让顺向啮合部433处于脱离状态。手柄本体41采用螺钉联接的上下盖结构。
为了便于对手柄本体的操作，能够起到防滑的作用，在手柄本体的上下盖表面设有若干个防滑凸点412。为了便于把持手柄本体，手柄本体的外形采用了弧形结构。
其中，上下盖采用塑胶件结构，为了固定预紧座45，在上下盖的空腔内设有筋板461、462，二者之间形成用于容置预紧座45的固定槽。
如图3所示，本发明 一种自动锁扣装置，包括组合式联接杆，及与杆体 10 的尾部联接的自动锁结构 S 。 如图4-图9所示，本发明 自动锁扣装置 中所采用的自动锁结构，包括与设有卡接槽11的杆体10可拆式联接的固定座管20；固定座管20的前端为用于插入联接杆的插孔部21，固定座管20的后端还联接有固定盖22；插孔部21的圆壁上环向设有六个钢珠孔210；钢珠孔210内设有可以径向活动的钢珠23；还包括套设于固定座管20外周且弹性止抵于固定盖22的外套筒31和位于插孔部21后端且弹性止抵于固定盖22的内套筒32；外套筒31的前端设有用于容置向外排出的钢珠23的回退槽311；固定盖22的外周设有向前延伸的凸起部221；外套筒31的后端设有与凸起部221相对应的锁止槽312和开启槽313；外套筒31旋转至开启槽313对应凸起部221时，当其向后端滑动至回退槽311对应于钢珠孔210，内套筒32在弹性力的作用下，处于前端位置，挡住钢珠23向中心移动，钢珠23进一步挡住外套筒31向前端移动，保持在后端的位置，即内套筒32位于最前端，挡住钢珠23不向内侧移动，未插入杆体10时，内套筒32一直保持在前端的位置，外套筒31一直保持在后端的位置。当杆体10从固定座管20的前端插入至插孔部21，内套筒32受压向后端移动，钢珠23向外挤出至回退槽311；杆体10的卡接槽11对应于钢珠孔210的位置时，外套筒31受弹性力向前端滑动，钢珠23与外套筒31的接触点由回退槽311滑至外套筒31的内孔壁319，钢珠23受力向内压缩并置于卡接槽11内，这样可以实现自动锁紧，为了更加安全，防止外套筒受到非正常外力的作用而发生移动，可以将外套筒31旋转至锁止槽312对应于凸起部221。为了操作方便，本实施例设计为旋转90度。其中，锁止槽的深度远远小于开启槽的深度，锁止槽对应于凸起部时，外套筒只能轴向活动几毫米的行程。
还包括套设于固定盖22外周的外弹簧222（作用于外套筒31），固定盖22设有内孔220，内孔220设有内弹簧223（作用于内套筒32）。固定座管20的后端设有内凸缘201；内套筒32设有与插孔部21配合的前端滑动部329和与内凸缘201配合的后端滑动部328；内套筒32的后端还联接有止抵于固定座管20后端面的内端盖33，内弹簧223作用于内端盖33。
为了便于加工和安装，固定盖22与固定座管20为螺丝联接，内端盖33与内套筒32也为螺丝联接。
锁止槽312与开启槽313之间设有过渡槽部314；外弹簧222的后端与固定盖22的后端外周固定联接，外弹簧222的前端与外套筒31的后端固定联接；过渡槽部314与凸起部221对应时，外套筒31受外弹簧222的向后拉力（这种向后拉力可以让外套筒处于锁止位置时，在无外力作用的情况下，凸起部始终处于锁止槽，而不会自动滑出至过渡槽部314）。为了实现这个向后拉力，固定盖22的后端外周设有与外弹簧222后端内孔过盈配合的凸台联接部（图中未示出）；外套筒31的后端设有用于容置外弹簧222的弹簧孔，弹簧孔的底部设有与外弹簧前端外圆过盈配合的内联接部（图中未示出）。
为了实现固定座管20的安装，在其前端设有径向外侧方向延伸的凸边202，凸边202设有安装孔203。外套筒31的外周还设有防滑环向槽317。
总之， 本发明手柄采用了双向调节柄，可以通过对拔动部的操作，切换双向调节柄的逆向啮合部或顺向啮合部与环向齿状部啮合，实现手柄本体与螺母之间的逆时针方向或顺时针方向的传动联接，而反向旋转时，由于三角形齿会向外的分力，从而使手柄本体与螺母处于分离状态，由此实现手柄本体与螺母之间的双向可分离式传动联接，将手柄与杆体成为一个整体，适合用于狭小空间的联接，并且免工具操作，十分地方便。与自动锁结构组合在一起使用时，还可以实现二个工件之间的快速安装，十分适合用于 LED 显示屏中的各个箱体之间的紧固联接。
上述仅以实施例来进一步说明本发明的技术内容，以便于读者更容易理解，但不代表本发明的实施方式仅限于此，任何依本发明所做的技术延伸或再创造，均受本发明的保护。本发明的保护范围以权利要求书为准。
