[0006] As an improvement of the above technical solution: the wire body includes an insulating tube, a plurality of wire cores distributed at equal distances are arranged inside the insulating tube, a shielding layer is fixedly connected to the outside of the insulating tube, and a protective inner layer is arranged on the outside of the shielding layer.

[0007] As an improvement of the above technical solution: through holes are provided at both ends of the support shaft, and the other end of the through hole penetrates to the outside of the support shaft.

[0008] As an improvement of the above technical solution: the connecting frame is U-shaped, the elastic part includes elastic blocks fixedly connected to two sides of the inner wall of the connecting frame, and the ends of the two elastic blocks facing each other are arc-shaped.

[0009] As an improvement of the above technical solution: one end of the support shaft is fixedly connected to the outer side of the reinforcing core through a connecting block, and one of the connecting frames on the support shaft is fixedly connected to the inner side of the supporting layer.

[0011] Beneficial effects of the utility model:

[0012] When the control cable of the present application is laid or used, the cooperation between the support tube and the filling cotton can minimize the tension on the insulating tube, thereby preliminarily protecting the wire body. The wire body is then wound around the support shaft so that the pulling force on the wire body is evenly dispersed, further preventing the wire body from being subjected to excessive tension. When the wire body is pulled at both ends, the elastic blocks on both sides of the multiple connecting frames can buffer the pulling force on both ends of the wire body, thereby effectively avoiding the wire body from being subjected to tension and effectively protecting the wire body in the cable.
