[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] The low-wear wire guide is provided with a support structure. When the wire passes through between two wire guide hole columns, it drives the wire guide roller shaft to rotate. On this basis, the wire guide roller shaft is driven by a worm gear block and a compression spring, so that the moving rod reciprocates left and right inside the mounting hole and outside the support rod. In this way, when the wire passes over the top of the wire guide roller shaft, it can evenly pass over the top of the wire guide roller shaft, avoiding long-term contact wear with the wire guide roller shaft at the same position. This design greatly improves the service life of the wire guide roller shaft;

[0017] Further, in the initial state of the device, the compression spring applies a force to the moving rod in the direction of the outside of the mounting hole, so that the wire guide roller shaft is located on the right side of the top of the moving block. At this time, the limiting ring reaches the shortest distance from the mounting hole. Through the action of the tension spring, the moving block slides inside the chute and on the top of the mounting block, so that the worm gear block is in close contact with the threaded ring. At this time, the wire passes through the wire guide hole column and moves, driving the wire guide roller shaft to rotate;

[0018] Further, during the rotation of the wire guide roller shaft, the wire guide roller shaft drives the threaded ring to rotate, so that the threaded ring moves outside the worm gear block, thereby driving the wire guide roller shaft and the limiting ring away from the side of the positioning plate. At this time, the wire guide roller shaft drives the moving rod to move, compressing the compression spring. When the wire passes over the top of the wire guide roller shaft, it can evenly pass over the top of the wire guide roller shaft;

[0019] Further, when the wire guide roller shaft moves to the side away from the positioning plate, the wire guide roller shaft drives the trigger disc to move outside the reserved groove, so that the trigger disc drives the two elastic pieces to separate from the inside of the rotating shaft. The ratchet structure formed by the annularly distributed card slots inside the rotating shaft and the two symmetrically distributed elastic pieces is separated. At this time, high-pressure gas is filled into the air valve, so that the pneumatic rod drives the moving block to move to the rear side of the mounting block through the high-pressure gas inside the air valve. At this time, the moving block drives the worm gear block away from the threaded ring. Since the threaded ring is separated from the worm gear block, the compression spring drives the moving rod away from the positioning plate, so that the wire guide roller shaft approaches the positioning plate, thereby returning the wire guide roller shaft to the initial state;

[0020] Further, when the wire guide roller shaft is in the initial state, the gas inside the pneumatic rod is discharged. At this time, the tension spring pulls the moving block to move, so that the worm gear block is in close contact with the threaded ring again, and the elastic pieces are reinstalled in the annularly distributed card slots inside the rotating shaft. The ratchet structure fixes the position of the moving block on the top of the mounting block. Description of the Drawings

A wire guiding roller shaft 12 is rotatably connected outside the moving rod 15, and threaded rings 13 and limiting rings 14 are respectively fixedly connected to both ends of the wire guiding roller shaft 12.

A moving block 9 is slidably connected inside the chute 2, a worm gear block 10 is fixedly connected to one side of the top of the moving block 9, and wire guiding hole columns 11 are fixedly connected to the side surfaces of the top of the moving block 9. A wire passes through the wire guiding hole columns 11, and the wire is slidably connected to the outside of the wire guiding roller shaft 12. A connecting cross bar 5 is fixedly connected to the bottom of the mounting block 1, an air valve 6 is fixedly connected to the middle of the connecting cross bar 5, and a rotating hole 7 is provided inside the inner side of the connecting cross bar 5. A reserved groove 8 is provided on one side of the mounting block 1, the trigger disc 18 is slidably connected inside the reserved groove 8, and the lower end of the trigger disc 18 is slidably connected inside the rotating hole 7.

A spring is provided outside the lower end of the trigger disc 18, and the spring connects the lower end of the trigger disc 18 and the rotating hole 7, and a piston structure is formed between the lower end of the trigger disc 18 and the rotating hole 7. A rack 22 is fixedly connected to the bottom of the moving block 9, and the rack 22 is composed of a plurality of equidistantly distributed teeth, and the rack 22 meshes with the outside of the gear 21. A tension spring 23 is fixedly connected to the side of the connecting cross bar 5 away from the air valve 6, and a pneumatic rod 24 is provided inside the tension spring 23. The pneumatic rod 24 is fixedly connected to one side of the connecting cross bar 5, and the inside of the pneumatic rod 24 communicates with the air valve 6. The sides of the tension spring 23 and the pneumatic rod 24 away from the connecting cross bar 5 are both fixedly connected to the bottom of the moving block 9;

[0030] When the wire passes through between the two wire guiding hole columns 11, it drives the wire guiding roller shaft 12 to rotate. On this basis, the wire guiding roller shaft 12 is driven by the worm gear block 10 and the compression spring 16, so that the moving rod 15 makes left - right reciprocating movements inside the installation hole 4 and outside the support rod 17. In this way, when the wire passes over the wire guiding roller shaft 12, it can uniformly pass over the top of the wire guiding roller shaft 12, avoiding long - term contact wear with the wire guiding roller shaft 12 at the same position. This design greatly improves the service life of the wire guiding roller shaft 12;

[0031] In the initial state of the device, the compression spring 16 exerts a force on the moving rod 15 in the direction outside the mounting hole 4, such that the wire guiding roller shaft 12 is located on the upper right side of the moving block 9. At this time, the limiting ring 14 reaches the shortest distance from the mounting hole 4. Under the action of the tension spring 23, the moving block 9 slides inside the chute 2 and on the top of the mounting block 1, making the worm gear block 10 in close contact with the threaded ring 13. At this time, the wire passes through the wire guiding hole column 11 and moves, driving the rotation of the wire guiding roller shaft 12;

[0032] During the rotation of the wire guiding roller shaft 12, the wire guiding roller shaft 12 drives the rotation of the threaded ring 13, causing the threaded ring 13 to move outside the worm gear block 10, thereby driving the wire guiding roller shaft 12 and the limiting ring 14 away from the side of the positioning plate 3. At this time, the wire guiding roller shaft 12 drives the moving rod 15 to move, compressing the compression spring 16. When the wire passes over the top of the wire guiding roller shaft 12, it can uniformly pass through the top of the wire guiding roller shaft 12;

[0033] When the wire guiding roller shaft 12 moves to the side away from the positioning plate 3, the wire guiding roller shaft 12 drives the trigger disc 18 to move outside the reserved groove 8, causing the trigger disc 18 to drive the separation of the two elastic pieces 19 from the inside of the rotating shaft 20. The annularly distributed card slots inside the rotating shaft 20 and the two symmetrically distributed elastic pieces 19 form a ratchet structure separation. At this time, high-pressure gas is filled into the air valve 6, and the pneumatic rod 24 drives the moving block 9 to move to the rear side of the mounting block 1 through the high-pressure gas inside the air valve 6. At this time, the moving block 9 drives the worm gear block 10 away from the threaded ring 13. Since the threaded ring 13 is separated from the worm gear block 10, the compression spring 16 drives the moving rod 15 away from the positioning plate 3, making the wire guiding roller shaft 12 approach the positioning plate 3, so that the wire guiding roller shaft 12 returns to the initial state;

[0034] When the wire guiding roller shaft 12 is in the initial state, the gas inside the pneumatic rod 24 is discharged. At this time, the tension spring 23 pulls the moving block 9 to move, making the worm gear block 10 come into close contact with the threaded ring 13 again. The elastic piece 19 is reinstalled in the annularly distributed card slots inside the rotating shaft 20, and the ratchet structure fixes the position of the moving block 9 on the top of the mounting block 1.
