A detection mechanism 3 for detecting the cable is installed inside the clamping mechanism 2, and the detection mechanism 3 includes a plurality of contact components 4 that can contact and detect the cable, and a control component 5 that can process signal data collected by the contact component 4. In this embodiment, the detection mechanism 3 is arranged inside the clamping mechanism 2, wherein the contact components 4 in the detection mechanism 3 can move within the clamping mechanism 2, and the contact components 4 are provided in ten numbers and are arranged in a circular array in the middle of the clamping mechanism 2.

A second compression spring 16 is fixedly connected to the sliding block 15, and the other end of the second compression spring 16 is fixedly connected to the walking frame 14. A walking wheel 17 that can contact the cable is rotatably connected to the sliding block 15, and the middle part of the walking wheel 17 is opened into a concave arc shape to facilitate adapting to the shape of the cable.
