By arranging the connecting piece 3, the first shell 201 and the connecting screw 203, the connecting screw 203 can be screwed into and out of the connecting piece 3 during use, so that the bendable part 1 and the unbendable part 2 can be quickly assembled and disassembled, the work efficiency is greatly improved, and the bendable part 1 and the unbendable part 2 can be disassembled into two parts when carrying, the overall length is reduced, the carrying out is facilitated, the copper nose 103 is arranged, the stable connection of the test wire clamp is facilitated during use, and the contact area is increased.

[0032] The connecting piece 3 comprises a second shell 301, and a mounting seat 303 and a second nut 302 for connecting the bendable part 1 and the unbendable part 2 are arranged in the second shell 301. One end of the mounting seat 303 is provided with a groove matched with the cable 101. The second shell 301 and the first shell 201 are both made of resin. By arranging the mounting seat 303 and the groove, the cable 101 can be inserted into the mounting seat 303 and then fixed by welding or other means, so that the connection strength between the cable 101 and the mounting seat 303 is improved. By arranging the second nut 302 and the connecting screw 203, the connection between the unbendable part 2 and the connecting piece 3 is facilitated.

[0033] The unbendable part 2 comprises a connecting screw 203 threadedly connected to the connecting piece 3. The outer side of the connecting screw 203 is fixedly connected with the first shell 201. One end of the connecting screw 203 extends outward through the first shell 201 and is threadedly connected with the second nut 302. The other end of the connecting screw 203 is fixedly connected with a first nut 204. By arranging the bendable part 1 and the unbendable part 2, when working in a narrow space of a ring main unit, the extension rod can be bent by the bendable part 1 to increase the distance between phases, so that safety hazards caused by too small distance between phases are avoided. The first nut 204 arranged in the first shell 201 can be connected with a threaded cable terminal.
