[0025] Specifically, a pulling groove 56 is formed at one end of the rotating arm 55, and a connecting rod 57 is slidably connected inside the pulling groove 56.

[0026] In this embodiment: By arranging the connecting rod 57 inside the rotating arm 55, the rotating arm 55 can be extended and rotated, reducing the situation that it is difficult for the user to rotate the rotating arm 55 when the device is in use.

[0027] Specifically, clamping blocks 58 are fixedly connected to both ends of the connecting rod 57, and the clamping blocks 58 are clamped with the inner wall of the clamping hole 59. The clamping blocks 58 are arranged to facilitate the limitation of the connecting rod 57.

[0028] Specifically, a first spring 510 is fixedly connected inside the connecting rod 57, and one end of the first spring 510 away from the connecting rod 57 is fixedly connected to the inner wall of the pulling groove 56. The first spring 510 is arranged to facilitate applying an elastic force to the connecting rod 57.

[0029] In this embodiment: A connecting device 6 is arranged at the connection between the vertical rod 51 and the base 3. The connecting device 6 includes a connecting hole 61 and a connecting block 62. The connecting hole 61 is formed on the surface of the base 3, the connecting block 62 is fixedly connected to the bottom of the vertical column, the connecting block 62 is arranged with the inner wall of the connecting hole 61, a connecting plate 63 is slidably connected to the inner wall of the connecting block 62, the connecting plate 63 is slidably connected inside the base 3, and a clamping groove 65 is formed inside the connecting block 62.

[0030] In this embodiment: By arranging the connecting block 62 at one end of the vertical column, the vertical column can be positioned, reducing the situation that the vertical column cannot be restricted on the surface of the base 3 when the device is in use.

[0033] Working principle: Cable 2 is a device manufactured to meet optical, mechanical, or environmental performance specifications. It is a communication cable assembly that uses one or more optical fibers placed in a covering sheath as a transmission medium and can be used individually or in groups. When laying cable 2, the user will transport the cable using a vehicle to the location where it needs to be laid. When using the device, the user pulls the connecting rod 57. When the connecting rod 57 moves, it drives the block 58 to move out of the internal card hole 59. When the connecting rod 57 moves, it drives the first spring 510 to displace and deform to generate elastic force. When the block 58 disengages from the internal card hole 59, the rotating arm 55 loses its restraint, and the rotating arm 55 rotates out of the internal rotating ring 53. Immediately, the rotating ring 53 loses its restraint, and the cable 2 overflows from the internal rotating ring 53. By setting the slow-release device 5, the cable 2 is effectively restricted, which plays a role in restricting the cable 2. When the device is in use and the user is laying the cable 2, when the user pulls one end of the cable 2 to stretch and move it, the cable 2 is likely to wind and knot on the surface of the drum 1, causing the cable 2 to fold and be damaged, thus improving the practicality of the device.

[0034] When using the device, the user pulls the pull handle 68. The pull handle 68 drives the connecting plate 63 to move. When the connecting plate 63 moves, it pushes the ball 66 to move. When the ball 66 moves, it drives the second spring 67 to displace and deform to generate elastic force. Immediately, the ball 66 disengages from the internal card slot 65 and enters the internal sliding slot 64. The connecting plate 63 loses its restraint, and the connecting plate 63 is pulled out of the internal connecting block 62. The column loses its restraint. By setting the connecting device 6, the column is effectively stabilized, which plays a role in stabilizing the column. When the device is in use, the column is inserted and connected to the connecting hole 61. When using the cable 2, the column is likely to shake and easily disengage from the base 3, causing the cable 2 to be knocked and damaged, thus improving the practicality of the device.
