具体地，所述的旋转锁定结构包括旋转锁定连杆10和设置在所述的旋转锁定连杆10后部的复位弹性件12，所述的旋转锁定连杆10沿所述的手柄2前后方向设置于所述的手柄顶板16下面，所述的复位弹性件12向后抵靠所述的手柄2的内表面。具体地，所述的复位弹性件12优选为弹簧。所述的旋转锁定连杆10的上端面前后位置设置两个自锁凸台11，所述的手柄顶板16设置两个自锁开口，并且以所述的旋转轴套21为中心，在所述的机壳底板17上设置两个圆弧形的旋转槽25；所述的自锁凸台11通过所述的自锁开口卡入所述的旋转槽25。为了操作者解锁所述的旋转结构，所述的旋转锁定连杆10的前端伸出所述的手柄2的表面。
进一步地，在所述的旋转槽25的中心位置设置自锁卡口24，在所述的复位弹性件12的作用下，所述的自锁凸台11卡入所述的自锁卡口24，限制所述的主机壳体1的旋转。当操作者按下所述的旋转锁定连杆10，所述的复位弹性件12被压缩，所述的自锁凸台11位于所述的旋转槽25以内，不再受限，所述的主机壳体1可以进行旋转，选择操作模式。
除了上述优选实施例外，本发明还有其他的实施方式，本领域技术人员可以根据本发明做出各种改变和变形，只要不脱离本发明的精神，均应属于本发明所附权利要求所定义的范围。
