Left-right automatic head shaking mechanism of electric fan

The left-right automatic head shaking mechanism comprises a synchronous motor, one end of the synchronous motor is connected with a rotating iron shaft, the end of the rotating iron shaft is sleeved with a rotating shaft sleeve, the end of the rotating shaft sleeve is sleeved with a fixing base, and a splicing plate is fixed to the side wall of the rotating shaft sleeve. The end face of the spliceplate is connected with a connecting rod through a screw, the other end of the connecting rod is connected with a synchronous crank through a screw, a mounting plate is arranged at one end of the synchronous crank, and a supporting friction plate is arranged on the surface of one end of the mounting plate; according to the utility model, the designed rotating iron shaft has good strength, so thatthe synchronous motor is prevented from being damaged under the forward tilting action, the supporting strength of the synchronous motor is improved, and the designed supporting friction plate has good wear resistance, so tha
