when the third cord 28 on the third reel 46 is used up, the third cord 28 is not pulled by the third reel 46, the third cord 28 cannot press the knot detection wheel 71 downwards, because the second support spring 74 has elastic potential energy, the second rotating rod 76 is pushed by the second support spring 74 to move upwards, the second rotating rod 76 drives the knot detection wheel 71 to move upwards, the knot detection wheel 71 is not contacted with the second induction block 73, which indicates that no remaining cord exists on the third reel 46 at the moment, the movable resisting block 50 is electrified to generate attraction force at the moment, the movable resisting block 50 attracts the inner wall of the rear side of the movable resisting block sliding groove 84, the movable resisting block 50 slides towards the rear side, the movable resisting block 50 does not resist against the rotating shaft base 48, the reversing motor 86 starts to work, the reversing motor 86 drives the reversing motor shaft 51 to rotate clockwise, the reversing motor shaft 51 drives the rotating shaft base 48 to rotate one hundred eighty degrees clockwise, the third reel 46 falls into the recycling bin cavity 42, the reversing motor 86 drives the reversing motor shaft 51 to rotate reversely, the reversing motor shaft 51 drives the rotating shaft base 48 to rotate one hundred eighty degrees reversely, the movable abutting block 50 is powered off and loses attraction force, the abutting block spring 85 has elastic potential energy, the abutting block spring 85 pushes the movable abutting block 50 to move forwards, the movable abutting block 50 abuts against the rotating shaft base 48, meanwhile, the wire pressing block 80 is powered on to generate attraction force, the wire pressing block 80 attracts the inner wall of the lower side of the wire pressing cavity 78, the wire pressing block 80 moves downwards, and the wire pressing block 80 is matched with the wire pressing groove 81 and presses a wire tail tightly; when the device normally works, the actuating electromagnet 59 is electrified to generate attraction force, the actuating electromagnet 59 attracts the second pull plate 57 and the first connecting rod 55, the first connecting rod 55 drives the fourth push-pull rod 69 to rotate clockwise around the third rotating shaft 66, the second pull plate 57 drives the second push-pull rod 65 to rotate anticlockwise around the third rotating shaft 66, the second rotating shaft 64 to which the second push-pull rod 65 moves downwards, the fourth push-pull rod 69 drives the fourth rotating shaft 68 to move upwards, the second rotating shaft 64 drives the first push-pull rod 63 to rotate clockwise around the first rotating shaft 62, the third push-pull rod 67 drives the first rotating shaft 62 to rotate anticlockwise, the first rotating shaft 62 pushes the push-pull block 61 to move leftwards, the push-pull block 61 pushes the press plate 60 to move leftwards until the press plate 60 abuts against the reel, when the reel needs to be changed, the actuating electromagnet 59 is powered off to lose the attraction force, and the pull-up spring 54 pulls the first connecting rod 55 to the original position due, because the pull-down spring 58 has elastic potential energy, the pull-down spring 58 pulls the second connecting plate 56 to return to the original position, the pressing plate 60 returns to the original position, the pressing plate 60 does not extrude the reel, the second reel 18 falls off, then the electromagnet 59 is actuated to electrify, the pressing plate 60 extrudes the first reel 15, and the first reel 15 is left in the reel bin cavity 14; the second wire wheel 18 falls on the surface wheel 43, the second wire wheel 18 is sleeved on the wire shaft 47, the second wire rope 20 presses the loading detection wheel 23, the loading detection wheel 23 moves downwards, the loading detection wheel 23 contacts the first induction block 25, and the fact that the second wire wheel 18 is loaded at the moment can start knotting is shown.
