Further, the bottom end of the vertical plate 13 is bent and extended towards the direction close to the supporting arm 14 to form a stopping arm 16, the stopping arm 16 is located below the supporting arm 14, and the stopping arm 16 is used for stopping the supporting arm 14.

As can be seen from the above description, the stop arm 16 can provide better support for the support arm 14, further improving the structural stability of the cable clamp 1.

Further, a force unloading groove 18 is arranged at the joint of the stop arm 16 and the vertical plate 13.

As can be seen from the above description, the force-releasing slot 18 improves the stress concentration at the connection between the stopper arm 16 and the riser 13, so that the cable clamp 1 is durable.

Further, at least one side of the vertical plate 13 extends outwards to form an extension plate 19.

Further, the riser 13 has the extension plates 19 on opposite sides thereof, respectively.

Further, the vertical plate 13 and the two extension plates 19 form a concave structure.
