The supporting mechanism includes a support fixedly connected with the cylinder, and a rotating mechanism fixedly connected with the bottom end of the support. The rotating mechanism includes a bottom support, a pedal arranged at one end of the bottom support, a plug pin, and a turnplate body matched and connected with the plug pin, and the turnplate body is fixedly connected with the bottom of the cylinder.

What is claimed is: 
     
         1 . A universal rotary fan, including
 a supporting mechanism,   a cylinder mounted on the supporting mechanism,   a front net cover and a rear net cover arranged respectively on a front end face and a rear end face of the cylinder,   fan blades are located inside the cylinder, and   a control mechanism electrically connected with the fan blades,   wherein, the supporting mechanism includes a support fixedly connected with the cylinder, and a rotating mechanism fixedly connected with the bottom end of the support; the rotating mechanism includes a bottom support, a pedal arranged at one end of the bottom support, a plug pin connected with the pedal through a steel wire, and a turnplate body matched connected with the plug pin, and the turnplate body is fixedly connected with a bottom of the cylinder.   
     
     
         2 . The universal rotary fan according to  claim 1 , wherein a bottom of the turnplate body is in a shape of a round flat-bottom vessel, and a wall of the turnplate body is provided with a plurality of positioning holes that are matched with the plug pin. 
     
     
         3 . The universal rotary fan according to  claim 2 , the rotating mechanism further includes a turnplate base, wherein a middle portion of the turnplate base is concave inwards and matched with an outside of the turnplate body, and a through hole matched with the plug pin is formed in a side, where the plug pin is located, of the wall formed through the inward concave middle portion of the turnplate base. 
     
     
         4 . The universal rotary fan according to  claim 3 , wherein a plug pin guide base is sheathed outside the plug pin, clamped outside the through hole in the turnplate base. 
     
     
         5 . The universal rotary fan according to  claim 1 , wherein the center between the turnplate body and the turnplate base is provided with central through holes that are interconnected, through which both of them can be coaxially connected with each other. 
     
     
         6 . The universal rotary fan according to  claim 5 , wherein the turnplate body and the turnplate base are coaxially connected through a bolt and a nut. 
     
     
         7 . The universal rotary fan according to  claim 6 , wherein two wheels are coaxially arranged at an end, away from the pedal, of the bottom support. 
     
     
         8 . The universal rotary fan according to  claim 5 , wherein two supporting legs are arranged at the bottom of the other end, opposite to the two wheels, of the bottom support, and the bottom surfaces of the two supporting legs and the bottom surfaces of the two wheels are located on the same horizontal plane.
