step two, a second pushing cylinder (7) drives a wire stripping mechanism (6) to be close to a wire pressing table (22), meanwhile drives a pushing block (43) to move, a three-wire plug is moved to a socket groove (52), then a wire cutting knife (63) is closed to cut the surface of the inner wire of the connecting wire, and the second pushing cylinder (7) drives the wire stripping mechanism (6) to be far away from the wire pressing table (22), so that the surface of the inner wire of the connecting wire is stripped; simultaneously, the pushing block (43) moves to the original position, and the three-wire plug slides from the feeding groove (42) to the material guiding channel (41).

Step three, a first pushing cylinder (9) drives a sliding seat (21) to move towards a riveting platform (5), an inner line of a connecting line respectively penetrates through a guide groove (541) on a guide seat (54) and is in contact with a plug riveting end, a second lifting cylinder (32) drives a first pressing block (34) to descend, the first pressing block (34) drives a riveting block (532) to descend, and two adjacent riveting blocks (532) are pressed on the middle plug riveting end, so that the connecting line is connected with the plug in a riveting mode.
