A 360-degree fan able to rotate about their mean positions, it comprises of two fan blades which means one at the front and other at the back. Usually, a normal table fan rotates approximately at 180-190 degrees in which we take it as 180 degrees. But in this model, we have created we have two fan blades in which one fan blade rotates at 180 degree and other blade also rotates at 180 degrees at last it results in 360-degree rotation. It includes a control device consisting of a left and right shell combined. 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.
