[0026] Reset component includes the rotating shaft 10 for supporting, and the rotating shaft 10 is rotatably connected in the inside of through groove 9, and the outside of rotating shaft 10 is fixedly sleeved with the connecting plate 12 for connecting, and the both ends of connecting plate 12 extend out of through groove 9.

[0027] The both side surfaces of connecting plate 12 are fixedly connected with torsion spring 11 for the reset of connecting plate 12, and the other end of torsion spring 11 is fixedly connected with the inner wall of through groove 9, and torsion spring 11 movably sleeves the outside of rotating shaft 10, by staff to move connecting plate 12, at this time, connecting plate 12 will rotate with rotating shaft 10 as the shaft, to drive torsion spring 11 to produce elastic deformation, so as to facilitate the reset of connecting plate 12 by the elastic potential energy stored in torsion spring 11 subsequently.

[0028] The both side surfaces of connecting plate 12 are fixedly connected with torsion spring 11 for the reset of connecting plate 12, and the other end of torsion spring 11 is fixedly connected with the inner wall of through groove 9, and torsion spring 11 movably sleeves the outside of rotating shaft 10, by staff to move connecting plate 12, at this time, connecting plate 12 will rotate with rotating shaft 10 as the shaft, to drive torsion spring 11 to produce elastic deformation, so as to facilitate the reset of connecting plate 12 by the elastic potential energy stored in torsion spring 11 subsequently.

[0029] The outside of rotating ring 6 is slidably sleeved with the driving ring 18 convenient for user operation, and the outside of rotating ring 6 is fixedly connected with four positioning blocks 19, and the driving ring 18 is located between positioning block 19 and connecting plate 12, when staff needs to lay cable, first pushes the driving ring 18 and slides in the outside of rotating ring 6, at this time, the driving ring 18 will force connecting plate 12 to rotate, to drive guide pulley 7 to rotate, then the cable outside cable roller shaft 2 is passed between two guide pulleys 7, and subsequently slowly releases the driving ring 18 until the driving ring 18 is again abutted with positioning block 19, to be able to restrict the cable in the inside of wire groove 8 on the surface of two guide pulleys 7, to facilitate subsequent traction of the cable.

[0030] In the above embodiment, when the cable is pulled for traction, the guide wheel 7 will not rotate at this time, thus ensuring the stability of the traction cable, because the positioning block 19 limits the driving ring 18, and the connecting plate 12 is limited by the driving ring 18.

[0032] The lower surface of the adjusting plate 4 is fixedly connected with a second connecting piece 14, and the second connecting piece 14 and the first connecting piece 22 are rotationally connected with a lifting plate 15 for adjusting the height of the adjusting plate 4 through a shaft body. When the sliding seat 21 slides in the interior of the guide groove 20, because the length of the lifting plate 15 is fixed, when the lower end of the lifting plate 15 moves forward along with the first connecting piece 22, the front end of the adjusting plate 4 will be lifted upward, and when the lower end of the lifting plate 15 moves rightward along with the first connecting piece 22, the lower end of the adjusting plate 4 will be lowered, thus realizing the adjustment of the laying height of the cable.

The rotation of the threaded rod 16 can be adjusted by rotating the crank handle 17, and the movement of the sliding seat 21 can be driven by the rotation of the threaded rod 16.

[0034] Working principle:

[0035] When the cable laying cable traction device is used, when the staff needs to lay the cable, the driving ring 18 is first pushed to slide on the exterior of the rotating ring 6, at this time the driving ring 18 will force the connecting plate 12 to rotate, at this time the connecting plate 12 will rotate around the rotating shaft 10, thus driving the torsional spring 11 to elastically deform, the rotation of the connecting plate 12 can drive the rotation of the U-shaped frame 13, thus driving the rotation of the guide wheel 7, then the cable outside the cable roller shaft 2 is passed between the two guide wheels 7, and then the driving ring 18 is slowly loosened until the driving ring 18 abuts against the positioning block 19 again. In this process, the elastic potential energy stored in the torsional spring 11 can drive the connecting plate 12 and the U-shaped frame 13 to reset, thus being able to limit the cable in the interior of the wire grooves 8 on the surfaces of the two guide wheels 7, so as to facilitate the subsequent traction of the cable.

[0036] If the laying angle changes, at this time the cable will drive the guide wheel 7 and the rotating ring 6 to freely rotate in the interior of the fixed plate 5 under the action of the two guide wheels 7, thus effectively avoiding the bending of the cable when bending.

[0037] In addition, when the laying height needs to be adjusted, the rotation of the threaded rod 16 can be adjusted by rotating the handle 17, and the movement of the sliding seat 21 can be driven by the rotation of the threaded rod 16, when the sliding seat 21 slides in the guide groove 20, since the length of the lifting plate 15 is fixed, when the lower end of the lifting plate 15 moves forward along with the first connecting piece 22, the front end of the adjusting plate 4 is lifted upward, when the lower end of the lifting plate 15 moves right along with the first connecting piece 22, the lower end of the adjusting plate 4 is lowered, so that the adjustment of the cable laying height is realized.

[0038] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, the scope of the utility model is defined by the appended claims and their equivalents.
