A through - slot is opened on one of the winding rods, the rodless cylinder is fixed on the winding frame below the through - slot, and the shearing blade passing through the through - slot is fixed on the slider of the rodless cylinder.

[0009] Further, arc - shaped guide rods are fixed at both ends of the winding rod.

[0010] The advantages of the utility model are as follows: during operation, the end of the tying rope on the reel is tied to one of the winding rods, and the handle is manually driven to make the connecting disk drive the winding rods to rotate synchronously around the supporting shaft, and at the same time, the tying rope is gradually wound and tightened around the periphery of each winding rod. After winding several circles, a knife is inserted between the two winding rods to cut off the wound tying rope, so that multiple tying ropes are formed for tying and sealing; thus, the utility model can quickly cut out several short sections of tying ropes, which saves time and labor, reduces manual labor intensity, and improves work efficiency.

[0011] When it needs to be cut after being wound several times, the rodless cylinder is controlled to move, and the slider on the rodless cylinder drives the shear blade to move from one end of the through slot to the other end. During this process, the wound tie rope is cut off to achieve the purpose of automatic cutting, further reduce labor intensity and improve work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
