[0059] Specific working principle: After the hosiery machine knits the sock tube, the sock tube is transferred to the toothed disc 81. The toothed disc 81 enters the toe linking position. Then, the second linear driver 33 acts to push the base 1 forward. The linking needle 2 and the supporting hook 23 move to the set position to start the toe linking operation. After the toe linking is completed, the second linear driver 33 reversely moves the base 1 by a certain stroke. The distance between the base 1 and the toothed disc 81 increases, and the space for the cutter holder 41 to enter is emptied. Then, the third linear driver 73 controls the cutter holder 41 to move towards the needle foot of the chain linking needle 2 until the needle foot enters the cutter opening 61. After the cutter holder 41 is in place, the first linear driver 50 acts to control the cutter 43 to axially move. In the process of the intersection of the cutter opening 61 and the top cutting surface of the fixed cutter 44, the yarn is cut off. After the yarn is cut, the cutter 43 and the cutter holder 41 are moved to the original position. The base 1 is further moved away from the toothed disc 81. The toe linking device is withdrawn. The semicircular split toothed disc of the toothed disc 81 is turned over. The hosiery with the linked toe is sucked out of the material by the corresponding negative pressure discharging mechanism.
