定位销滑块 32 ，其上设有定位孔 321 、连接孔 322 及滑槽 323 ，定位孔 321 设于定位销滑块 32 上表面垂直位置，连接孔 322 设于与定位孔 321 相交的横向位置，滑槽 323 设于定位销滑块 32 上的横向位置。
定位销 33 的下方设有第三通孔 331 。
使用时，定位销滑块 32 设于滑块安装位 312 内，定位销 33 穿过定位销座 31 的定位孔 311 ，插设在定位销滑块 32 的定位孔 321 中，滑块销 35 穿过定位销滑块 32 的连接孔 322 的，穿过定位销 33 的第三通孔 331 ，使定位销 33 与定位销滑块 32 固设。连接轴 24 的另一端，是位于定位销滑块 32 的滑槽 323 中。
吊杆 4 的上端成形为环状 41 ，其可挂在一挂钉 A 上，吊杆 4 的下端设有连接孔 42 ，传动组件 2 通过连接轴 24 与吊杆 4 的连接孔 42 相连。
参考图 2 、 6 所示，吊杆 4 的环状 41 挂在挂钉 A 上， 实现锁紧与吊装连接功能。扳动手板柄 11 使其顺时针旋转 45° ，转矩大于复位弹簧 5 的转矩后，驱动手扳转轴 3 、挂钩限位件 17 、保险挂钩 12 作顺时针旋转，以致保险挂钩 12 与保险扣 161 分离，拉动旋转手柄 10 即可打开设备的门或盖；关闭设备的门或盖时，保险扣 161 与保险挂钩 12 触碰，转矩大于复位件 15 的转矩后，驱动保险挂钩 12 逆时针转动，待设备的门或盖关闭后，复位弹簧 5 转矩驱动挂钩限位件 17 、保险挂钩 12 逆时针旋转，从而扣住保险扣 161 ，实现自动扣紧功能，在此期间，复位弹簧 5 始终提供转矩驱动挂钩限位件 17 、保险挂钩 12 逆时针旋转扣住保险扣 161 ，实现防松、保险作用。同时，扳动手板柄 11 还可使其作为驱动件，通过 定位销 23 ，驱动凸轮组件 2 的凸轮 22 转动，凸轮 22 通过与吊杆 4 相连的连接轴 24 ，驱动吊杆 4 ，使吊杆 4 作伸缩运动；同时，凸轮 22 的连接轴 24 还驱动定位销滑块 32 ，定位销滑块 32 进行上下运作，即带动与其相连的定位销 33 进行上下动作，使定位销 33 顶出或退回，且该动作与吊杆 4 的动作匹配。即本发明需要松开时，反下手板柄 11 ，吊杆 4 伸出，定位销 33 退回，需要锁紧时，合上手板柄 11 ，同时吊杆 4 锁紧，定位销 33 顶出，从而实现了快速拆装的目的。
综上所述，本发明采用采用如上设计， 支持单个箱体从屏体当中的任意位置进行快速拆装，并且非常方便、快捷；另外，在狭小空间内 (45mm*51mm*136mm) ，实现高精度定位、强力锁紧 ( 大于 1000Kg ，作吊装机构用 ) ，并且操作方便；再者，所有零件结构简单，容易加工，适合批量化生产，从而成本低。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
