| Summary: | The pattern needle fixing device of the sewing machine comprises a swing mechanism and a swing needle driving mechanism, the swing mechanism is in transmission connection with a transmission shaft through tooth meshing, the transmission shaft is sleeved with at least one set of magnetic assembly, and a Hall assembly is arranged beside the magnetic assembly; the swing needle driving mechanism is connected with the swing assembly which is in swing connection with one end of the swing needle connecting rod, and the other end of the swing needle connecting rod is connected with the needle rod frame. The required transmission ratio is achieved through a mechanical structure, then the magnetic steel installed in the fixing ring rotates by the 720-degree needle stopping angle, an instruction is sent out to the motor to control swing, the mechanical structure is driven to enable the required needle rod frame to meet the stopping position requirements of different positions, and the requirement for controlling and com |
