[0020] As Figure 1 The bottom end of ring type frame 2 is open, so that the cable can pass through, facilitating the clamping and isolation of the cable fault part by arc plate 5, and the telescopic insulating rod 3 at one end of docking box 1 facilitates the isolation of the cable fault part from a distance.

[0021] The number of docking plate 4 and arc plate 5 is two respectively, the top of arc plate 5 is fixedly connected with limiting strip, the bottom of docking plate 4 is provided with slide cooperating with limiting strip, facilitating the sliding of limiting strip in the slide, facilitating the disassembly and assembly in the later period, and facilitating the replacement of the next group of arc plates for use.

[0022] Telescopic insulating rod 3 includes sleeve 301 fixedly connected at one end of docking box 1, support rod 302 arranged in sleeve 301 away from one end of docking box 1, and handle cylinder 303 fixedly connected at one end of support rod 302 away from sleeve 301, the surface of sleeve 301 is threadedly connected with positioning ring, fastener 6 includes auxiliary ring 601 rotatably connected in the inside of ring type frame 2, horizontal rod 602 arranged at one side of auxiliary ring 601, and fastening band 603 wound on the surface of horizontal rod 602.
