Then, the inside of the fixing ring 91 is in a power-on state by the external power supply of the lead, the lead cylinder 1001 is inserted into the fixing hole 802 through the fixing pile 1013, and the pressing plate 10131 is pulled to press the push rod 10132, so that the push rod 10132 pushes the push rod 10133 to abut against the inner wall of the fixing hole 802, and the connection between the lead cylinder 1001 and the connection ring 801 is completed.

Then, the yarn on the yarn frame 4 firstly passes through the space between the second guide wheel 1007 and the lever 1008, the yarn separates the second guide wheel 1007 and the lever 1008, the lever 1008 rotates clockwise at a microspur by taking a hinging shaft connected with the lever 1008 as a circle center, the lever 1008 drives the first conductive pile 1010 to rotate clockwise and separate from the second conductive pile 1011, the electromagnetic block 1004 is powered off and loses magnetic force, the yarn then passes through the space between the first guide wheel 1003 and the yarn clamping block 1005, when the yarn is cut off and passes through the space between the second guide wheel 1007 and the lever 1008, the partition is lost between the second guide wheel 1007 and the lever 1008, the lever 1008 can rapidly recover to the original position, the first conductive pile 1010 and the second conductive pile 1011 are contacted and electrified, the electromagnetic block 1004 is electrified to generate magnetic force to adsorb the yarn clamping block 1005 to rotate clockwise, the top end of the yarn clamping block 1005 rapidly abuts against the first guide wheel 1003 to clamp the yarn between the first guide wheel 1003, and place the yarn to enter, when the broken wire is processed, the limiting sheet 1014 is only needed to be pulled upwards to remove the limiting of the connecting sleeve box 1002, and then the connecting sleeve box 1002 is rotated out from the wire guide cylinder 1001, so that the broken wire can be seen to be processed for re-wiring.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
