When the wire clamping driving mechanism 6 is a needle type air cylinder, the second lifting mechanism 8 comprises a lifting air cylinder and a lifting guide sliding rail assembly, two ends of the lifting air cylinder are respectively connected with the upper connecting plate 12 and the corresponding wire outlet mechanism 4, and a guide rail part and a sliding block part of the lifting guide sliding rail assembly, which are matched with each other, are respectively connected with the upper connecting plate 12 and the corresponding wire outlet mechanism 4.

When the wire clamping driving mechanism 6 is a cam driving mechanism, the second lifting mechanism 8 comprises a transverse pushing cylinder, a transverse pushing guide rail assembly, a lifting cylinder and a lifting guide rail assembly which are arranged on the upper connecting plate 12, a transverse pushing block is arranged at the movable end of the transverse pushing cylinder, a guide rail part and a sliding block part which are matched with the transverse pushing guide rail assembly are respectively connected with the transverse pushing block and the corresponding upper connecting plate 12, two ends of the lifting cylinder are respectively connected with the transverse pushing block and the corresponding wire outlet mechanism 4, a guide rail part and a sliding block part which are matched with the lifting guide rail assembly are respectively connected with the transverse pushing block and the corresponding wire outlet mechanism 4, and the corresponding wire clamping assembly 5 can avoid the corresponding cam 65 by using the transverse pushing cylinder and the transverse pushing guide rail assembly, so that the corresponding wire clamping assembly 5 and the corresponding cam 65 are prevented from interfering.

When the second lifting mechanism 8 is arranged and the wire outlet mechanism 4 positioned at the middle position is needed to be threaded, the lifting cylinder of the second lifting mechanism 8 works to lift the wire outlet mechanism 4 connected with the second lifting mechanism 8, so that the wire outlet mechanism 4 positioned at the middle position is convenient to thread the embroidery rope, and after the wire outlet mechanism 4 positioned at the middle position is threaded, the corresponding wire outlet mechanism 4 is restored to the original position by the lifting cylinder of the second lifting mechanism 8 to be ready for the embroidery rope work.
