[0031] The rotating structure 5 includes a bearing 51, a rotating rod 52, a first turntable 53 and a second turntable 54. The rotating rod 52 is sleeved on the bearing 51. The rotating rod 52 is fixedly connected to the first turntable 53. The first turntable 53 and the second turntable 54 are fixed by bolts. When the bearing 51 rotates, the rotating rod 52 will rotate accordingly, and thus the first turntable 53 and the second turntable 54 can be rotated together.

[0032] The expansion structure 6 includes a threaded rod 61, a sleeve 62, a connection groove 63 and a connection block 64. A sleeve 62 is provided on the left side of the threaded rod 61. Connection grooves 63 are formed on both sides inside the sleeve 62. A connection block 64 is provided inside the left connection groove 63. The sleeve 62 can be replaced with sleeves 62 of different lengths according to the usage requirements.

[0033] The connection block 64 and the sleeve 62 are fixed by bolts. The threaded rod 61 is threadedly connected to the sleeve 62. When replacing the sleeve 62, first, the bolts need to be loosened to disengage the threads between the connection block 64 and the sleeve 62, and then the sleeve 62 is rotated to disengage the threaded rod 61 from the sleeve 62.

[0034] The moving structure 2 includes a slide rail 21, a slider 22 and a moving seat 23. Sliders 22 are slidably connected to the tops of the slide rails 21. The moving seat 23 is fixedly connected to the tops of the sliders 22.

[0035] The working process of the present utility model: When using a cable traction device for cable laying, first, when performing the traction work, the drive motor 8 is connected to the second mounting seat 4. The drive motor 8 can drive the expansion structure 6 to rotate. When the bearing 51 rotates, the rotating rod 52 will rotate accordingly, and then the first turntable 53 and the second turntable 54 will rotate together. When replacing the sleeve 62 of different lengths, only need to loosen the bolts to disengage the threads between the connection block 64 and the sleeve 62, and then the moving structure 2 will be activated. At this time, the slider 22 will drive the equipment on the moving seat 23 and the first mounting seat 3 to move, increasing the distance between the two. Then, the sleeve 62 is rotated to disengage the threaded rod 61 from the sleeve 62, and then the sleeve 62 can be replaced. If the entire cable reel needs to be replaced, only need to remove the bolts between the first turntable 53 and the second turntable 54, and then connect the discs on both sides of the cable reel to the first turntable 53 and the second turntable 54 respectively, thus achieving the purpose of replacing different cable reels.
