当然，除此之外，所述弹性元件60还可采用弹性片等弹性元件60，但将弹性元件60采用弹簧，为本实用新型的最优实施方式，可降低成本，方便于安装。
所述锁定件40上设置有供弹性元件60嵌入的定位槽43，以方便于弹性元件60的安装定位。
所述定位套50上位于任意相邻的两嵌置槽51之间的部位形成为供锁定件40抵靠的抵靠部52，而在锁定件40随着旋转座30转动从嵌置槽51移向相邻抵靠部52时，所述锁定件40在抵靠部52的抵顶作用下后移向安装槽41内，所述弹簧处于压缩状态，而在锁定件40随着旋转座30转动从抵靠部52移向相邻嵌置槽51时，所述弹簧弹性复原，所述锁定件40在弹簧的弹性力作用下朝向定位套50方向移动并相应嵌置槽51内。
所述锁定件40为锁定销，所述锁定销设有横截面呈三角形状并用于嵌入嵌置槽51内的销头42。所述嵌置槽51的形状与销头42的形状相匹配。而通过采用上述结构，可方便于锁定件40嵌入和移出嵌置槽51内。
当然，除此之外，所述锁定件40还可采用柱芯、圆球体等，而作为本实用新型的另一优选实施方式，所述锁定件40可采用波珠，以在锁定件40随着旋转座30转动从抵靠部52移向相邻嵌置槽51时，所述波珠可在弹簧的弹性力作用下回弹，嵌入相应嵌置槽51内与嵌置槽51的槽壁发生碰撞发出响声，方便于使用者根据响声了解旋转座30连同保护壳20的转动情况，提高用户体验感。
所述支撑部件70包括固定在保护壳20上的支撑轴71，所述支撑轴71上设置有限位部72以及限位件80，所述旋转座30设有连接耳31，所述支撑轴71可转动地插装在连接耳31上，且连接耳31夹持在限位部72与限位件80之间，所述支撑轴71的中心轴线形成为所述第二旋转轴线。而通过推动保护壳20连同支撑轴71绕第二旋转轴线相对旋转座30的连接耳31转动，可绕第二旋转轴线调节保护壳20的转动角度，而待保护壳20转动到位，通过连接耳31与限位部72、限位件80之间的摩擦力（或者连接耳31与限位部72、限位件80之间的摩擦力、及支撑轴71与连接耳31之间的摩擦力）使得保护壳20保持在相应开合角度的位置处。
所述限位件80包括以可拆卸的方式连接在支撑轴71上的紧固件81、以及套装在支撑轴71上并位于连接耳31与紧固件81之间的若干个弹性垫圈82。所述限位件80还包括套装在支撑轴71上的第一垫圈83和第二垫圈84；所述第一垫圈83位于连接耳31和与连接耳31相邻的弹性垫圈82之间；所述第二垫圈84位于紧固件81和与紧固件81相邻的弹性垫圈82之间。
其中，所述紧固件81可为螺纹连接在支撑轴71上的锁紧螺母、或者卡装在支撑轴71上的卡圈等等。
所述限位部72包括设置在支撑轴71上的轴肩、以及位于轴肩与连接耳31之间的第三垫圈，以方便于安装、制作。当然，除此之外，所述限位部72还可为设置在支撑轴71上的卡圈等等，但将限位部72采用轴肩和第三垫圈，为本实用新型的最优实施方式，可方便于安装、制作。
而在本实施例中，所述支撑部件70包括固定在保护壳20上并呈相对设置的两支撑轴71，该两支撑轴71的中心轴线重合，所述旋转座30设有与该两支撑轴71分别一一对应的两连接耳31，所述支撑轴71可转动地插装在对应连接耳31上，以提高保护壳20转动的稳定性。
其中，所述键盘本体10的外壳、保护壳20的材质可依据实际需求而设置，作为本实用新型的进一步优选实施方式，所述键盘本体10的外壳、保护壳20可设置为透明闪亮状，可外显出键盘本体10内的元器件，形成赛博朋克风，并可提高外观效果,当然可以做成键盘本体多种颜色变化、灯光闪烁效果等等。
具体的，所述安装槽41沿着旋转座30的径向延伸。
在本实施例中，所述旋转座30包括支撑盘、固定在支撑盘上并插装在定位套50内的圆轮、以及固定在支撑盘上的连接架，所述安装槽41设置在圆轮上，所述连接耳31设置在连接架上，并朝上延伸。而通过采用上述结构，可方便于旋转座30的制作。
当然，除此之外，所述旋转座30还可采用其他结构，但将旋转座30采用支撑盘、圆轮、以及连接架的结合，为本实用新型的最优实施方式，可降低制作成本。
作为本实用新型的进一步优选实施方式，所述键盘本体10为蓝牙键盘本体，以方便于该蓝牙键盘本体10与平板电脑通过蓝牙无线方式连接。
上述实施方式仅为本实用新型的优选实施方式，不能以此来限定本实用新型保护的范围，本领域的技术人员在本实用新型的基础上所做的任何非实质性的变化及替换均属于本实用新型所要求保护的范围。
