[0002] The cable pay-out device is a device specially designed to support and release cables during cable laying. It helps construction workers place cables easily and orderly, ensuring that the cables are not damaged during the laying process while improving work efficiency.

[0003] After searching, the Chinese patent with the announcement number CN217808052U provides a device for installing a cable payout. The cable reel is set on the support rod, and the squeezing disc clamps the cable reel. The synchronous payout mechanism cooperates with the synchronous roller mechanism to synchronize the movement of the L-shaped mobile base with the payout, thereby effectively preventing the cable from being slack due to excessive release, improving the accuracy of cable usage, and when reversing, the cable can be reeled in synchronously, which is highly flexible.

[0004] However, it was found during use that when laying out the cables, the cable reels needed to be frequently put on the support rods. Since some cable reels were heavy, the process of putting them on the support rods was troublesome and laborious. When laying out cables of different sizes, the cable reels needed to be adjusted to the appropriate position on the support rods, which lacked sufficient convenience and affected the construction efficiency and the accuracy of cable laying.
