Reciprocator yarn swinging assembly with reverse yarn swinging function

The invention provides a reciprocator yarn swinging assembly with a reverse yarn swinging function. The reciprocator yarn swinging assembly comprises a motor transmission assembly, an eccentric wheel linkage mechanism and a reverse yarn swinging assembly of a reciprocator device. The upper end and the lower end of the motor are fixedly connected with one end of an output shaft A and one end of an output shaft B, and the output shaft A and the output shaft B reversely rotate. The other end of the output shaft A and the other end of the output shaft B are connected with a motor transmission mechanism, and the motor transmission mechanism is connected with the reverse yarn swinging assembly through the eccentric wheel linkage mechanism. Swinging pieces in the reverse yarn swinging assembly are fixed in a steel channel frame through bolts, and the steel channel frame is fixed to a support. A main connecting rod is arranged on one side face of the outer portion of the steel channel frame, the lower portion of the
