Clutch structure of heald selecting mechanism of weaving machine multi-arm device

The utility model discloses a clutch structure of a loom dobby device heald selecting mechanism, which comprises a drive shaft, a plurality of disk drives which are fixedly connected on the drive shaft, a plurality of sheaves which are rotatably matched with the drive shaft, wherein the disk drives are corresponding to the sheaves and each heald lifting arm of a loom, the rotation angle formed by the synchronous rotation of the disc drives with the drive shaft is in a functional relationship with the rotation angle of a loom spindle, and the sheaves can form four connecting bar mechanisms through connecting bars and the heald lifting arms. The mechanism is characterized in that an electromagnetic bolt clutch which enables the sheaves to be in a mesh form or a separated form with the disc drives is directly arranged on the disc drives, which is fixed on the disc drives through screws, and is extended towards the inner portion of the disc drives, and a jack which is corresponding to the mesh bolt of the electro
