[0032] 2. Through the stable support of the inner support rods and the inner sides of the cable reels, the present invention ensures that the cable reels can rotate smoothly with the winding base during the cable release process.

[0033] 3. The present invention can conveniently adjust and fix the supporting positions of the inner support rods through the displacement mechanism, so that cable reels of different sizes can be supported, and the device has stronger applicability and wider range.

[0034] 4. The present invention can automatically cut the cable by driving the cutting knife with the electric telescopic rod, and at the same time, extrude and fix the end of the cable, so as to facilitate the continuous pulling and wire threading at the next operation point and avoid the chaos and entanglement of the cables during the movement.

[0035] 5. The present invention can drive the clamping block on one side to synchronously extrude the cable while cutting the cable through the linkage component. And due to the action of the spring on the clamping block on the other side, the two oppositely arranged clamping blocks can clamp cables with different diameters, with stronger applicability. At the same time, when the end of the cable is in the clamped state, the cutting edge of the cutting knife is placed in the cutting groove, which ensures the safety of the device during movement.
