The top end of the base 1 is fixed with rotating shaft brackets 41 which are vertically and symmetrically arranged, and the two rotating shaft brackets 41 are vertically fixed on the base 1. The upper end of the rotating shaft support 41 is provided with a horizontally arranged rotating shaft 42, and an eccentric wheel 49 is fixed on the rotating shaft 42. The two ends of the rotating shaft 42 are rotatably connected to the corresponding rotating shaft brackets 41 through bearings, respectively. One end of the turning shaft 42 extends out of the turning shaft holder 41, and a second pulley 43 is fixed to this end of the turning shaft 42. The top of base 1 is fixed with motor fixing base 441, be fixed with three-phase asynchronous motor 44 on the motor fixing base 441, the top of base 1 is close to motor fixing base 441 and is fixed with the first pulley support 45 of vertical setting, be connected with first pulley axle 461 through the bearing rotation on the first pulley support 45, first pulley support 45 extends respectively at the both ends of first pulley axle 461, and the one end of first pulley axle 461 is fixed with first pulley 46, the other end of first pulley 46 passes through shaft coupling 48 and is connected with the power output shaft transmission of three-phase asynchronous motor 44, be equipped with belt 47 between first pulley 46 and the second pulley 43, first pulley 46 passes through belt 47 with power and transmits for second pulley 43.
