[0027] In this embodiment, the arrangement of the hinged plate 44 plays an effect of driving the movable plate 42 to move inside the vertical slot 41 .

[0028] Specifically, a limiting rod 46 is fixedly mounted on the surface of the operating plate 45, and a plurality of limiting holes 47 are formed in an annular shape on the outer wall surface of the rotating shaft 2. The setting of the limiting rod 46 and the limiting holes 47 has the effect of limiting the rotation of the rotating shaft 2.

[0029] In this embodiment: an adjusting device 5 is provided on the surface of the two vertical plates 6, and the adjusting device 5 includes a through groove 501, and the through groove 501 is opened on the surface of the two vertical plates 6, and a sliding rod 502 is fixedly installed between the inner walls of the upper and lower ends of the two through grooves 501, and the surfaces of the two sliding rods 502 are slidably connected with sliding plates 503, and a second guide wheel 504 is rotatably connected between the two sliding plates 503. When it is necessary to adjust the distance between the second guide wheel 504 and the first guide wheel 7, first rotate the rotating wheel 507. The rotation of the rotating wheel 507 drives the threaded rod 506 to rotate. The rotation of the threaded rod 506 drives the movable plate 509 to move inside the strip groove 508. The movement of the movable plate 509 inside the strip groove 508 drives the connecting rod 510 to move. The movement of the connecting rod 510 drives the sliding plate 503 to move on the surface of the sliding rod 502. The sliding plate 503 moves on the surface of the sliding rod 502 and drives the second guide wheel 504 to move. When the second guide wheel 504 moves to a suitable position, stop rotating the rotating wheel 507. Through the cooperation of the above-mentioned structure, the distance between the second guide wheel 504 and the first guide wheel 7 can be adjusted, thereby meeting the guiding operation of power lines of different sizes and further improving the adaptability of the device when used.

[0030] Specifically, a U-shaped plate 505 is fixedly installed on the surface of one of the vertical plates 6 , a threaded rod 506 is rotatably connected between the inner walls at both ends of the U-shaped plate 505 , and a rotating wheel 507 is fixedly installed at one end of the threaded rod 506 .

[0034] Working principle: By setting the limit device 4, when the wire laying work is carried out, the operating plate 45 is moved first, and the movement of the operating plate 45 drives the hinged plate 44 to move, and the movement of the hinged plate 44 pushes the two movable plates 42 to move away from each other inside the vertical groove 41, and the movement of the two movable plates 42 to move away from each other inside the vertical groove 41 will drive the spring 43 to stretch, and at the same time, the movement of the operating plate 45 also drives the limit rod 46 to move, and the limit rod 46 moves to move itself out of the limit hole 47, and the limit rod 46 and the limit hole 47 are separated to make the rotating shaft 2 lose Limiting, the shaft 2 loses the limit so that the winding roller 3 can rotate normally, and at this time you can pull one end of the power line to pass the power line between the first guide wheel 7 and the second guide wheel 504, so that the power line will not deviate at will when paying out, when the paying out is completed, release the operating panel 45, and use the rebound force of the spring 43 to reinsert the limiting rod 46 into the corresponding limiting hole 47 to re-limit the rotation of the shaft 2. Through the cooperation of the above structure, the winding roller 3 will not rotate after the paying out is completed, so that the power line can remain in a taut state. When it is necessary to adjust the distance between the second guide wheel 504 and the first guide wheel 7, first rotate the rotating wheel 507. The rotation of the rotating wheel 507 drives the threaded rod 506 to rotate. The rotation of the threaded rod 506 drives the movable plate 509 to move inside the strip groove 508. The movement of the movable plate 509 inside the strip groove 508 drives the connecting rod 510 to move. The movement of the connecting rod 510 drives the sliding plate 503 to move on the surface of the sliding rod 502. The sliding plate 503 moves on the surface of the sliding rod 502 and drives the second guide wheel 504 to move. When the second guide wheel 504 moves to a suitable position, stop rotating the rotating wheel 507. Through the cooperation of the above-mentioned structure, the distance between the second guide wheel 504 and the first guide wheel 7 can be adjusted, thereby meeting the guiding operation of power lines of different sizes and further improving the adaptability of the device when used.
