[0024] After the drive mechanism is activated, it can drive the connecting arm 6 to move back and forth, which in turn can drive the knife lifting assembly 7 to move back and forth to perform knitting work.

[0025] When the drive mechanism and guide rod 9 need to be lubricated after a long period of operation, lubricating oil can be injected into the interior of the transverse plate 16 and sprayed out through multiple spray nozzles 17 to apply lubricating oil between the two guide rods 9 and the guide cylinder 10 and on the surface of the drive mechanism.
