位于输出轴 30的上侧。 第一传动单元 40可传动地连接操作件 20和输出轴 30, 借此可通 过转动操作件 20驱动输出轴 30转动。 图 3显示了图 2所示结构的部分结构, 图 4显示了图 3所示结构的分解结构。 如图 3 和图 4所示,指示件 50沿一个平行于第一轴线 L1的第一方向 D1穿设于操作件 20并被设 置以能够相对于操作件 20绕第一轴线 L1转动。 指示件 50的沿第一方向 D1穿出操作件 20的一端 (即图 3和图 4中的下端) 连接输出轴 30以能够与输出轴 30同轴同角度转动。 在示意性实施方式中, 指示件 50与输出轴 30相互插接以形成键配合, 借此实现同轴同角 度转动, 但不限于此。在其他示意性实施方式中, 指示件 50例如也可以通过焊接、 卡扣连 接等方式与输出轴 30连接。 指示件 50的沿第一方向 D1 的反方向穿出操作件 20的一端 (即图 3和图
