    • An electric fan capable to rotate for 360 degrees includes a control device consisting of a left and a right shell combined together. The shells have a L-shaped steel plate inside to fix a motor and a speed-reducing device. The speed-reducing device has its spindle fitted with the fixed shaft of a clutch having bead hole for receiving two steel beads and a spring. A shaft sleeve has bead grooves for receiving two aforesaid steel beads and firmly fitted in a copper sleeve by a bolt screwing through a bolthole and resting against a concave groove of the stand post. The shells further have a shaft groove for receiving the upper half portion of the stand post, thus, the upper half portion is actuated by the control device to rotate with an angle from 0 degree to 360 degrees.
    • 能够旋转360度的电动风扇包括组合在一起的左右壳体的控制装置。 壳体内部有一个L形钢板,用于固定电机和减速装置。 减速装置的主轴装配有具有用于容纳两个钢珠和弹簧的胎圈孔的离合器的固定轴。 轴套具有用于接收两个上述钢珠的胎圈槽,并通过螺栓拧紧穿过螺栓并牢固地固定在铜套筒中,并抵靠在立柱的凹槽上。 壳体还具有用于容纳立柱的上半部的轴槽,因此,上半部分由控制装置致动以0度至360度的角度旋转。
