[0046] 3. After the shearing action is completed, the hydraulic motor 1 drives the transmission mandrel 3 to continue to rotate instantaneously, and the head and tail of the packing wire on the wire track 7 pass through the kink groove 30 on the wire track 7.

[0047] 4. When the instantaneous needle rotates, the tail and head of the baling wire in the wire slot rotate and twist instantly, and slowly slide out of the wire slot to achieve the purpose of baling.
