Based on the above scheme, the first conductive part 201 is in a circular truncated cone shape, that is, the radii of the holes are different, in order to facilitate understanding, the side with the largest radius of the first conductive part 201 is defined as the right side, the side with the smallest radius is defined as the left side, the elastic wire fixing mechanism 3 can move in the first conductive part 201, when the wire body is inserted into the first conductive part 201 from one end of the first conductive part 201 and is covered by the elastic wire fixing mechanism 3, the wire body can move towards the right side against the elastic wire fixing mechanism 3 until the elastic wire fixing mechanism 3 moves towards the right side in the first conductive part 201 to the maximum stroke, and in this time, the wire body is fully wrapped in the elastic wire fixing mechanism 3, because the elastic wire fixing mechanism 3 is elastic, in this state, the elastic wire fixing mechanism 3 can be initially locked, in order to further stabilize the locked wire body, a force can be applied on the fastener 6, so that the fastener 6 has a trend of moving leftwards, the conductive plate 5 is driven by the fastener 5 to further press the elastic piece 4, the elastic piece 4 is stressed to shrink the wire body, so that the elastic wire body can move towards the right side against the elastic wire fixing mechanism 3, and even if the elastic wire body is pulled towards the left side, the elastic wire fixing mechanism 3 is not pulled to the maximum stroke, or the elastic wire fixing mechanism is pulled out of the elastic wire fixing mechanism is more stable, and the wire fixing mechanism is prevented from moving towards the inner side, even if the elastic wire fixing mechanism is pulled to be more stable, the inner side, and the elastic wire fixing mechanism is easy to be pulled out from the wire fixing mechanism is easy to move or the wire fixing mechanism is broken to be broken; the cylinder 1 is fitted over the first conductive portion 201, and serves to fix the first conductive portion 201.

It should be noted that, in the above scheme, the electric wire body is inserted into the elastic wire fixing mechanism 3 and has at least two states, the first is that the elastic wire fixing mechanism 3 moves to the rightmost initial fixing state in the first conductive part 201, the second is that the elastic wire fixing mechanism 3 moves to the leftmost final fixing state in the first conductive part 201, the two states can respectively correspond to different use scenes, the first is applicable to the use scene with less strict requirements on the stability of the electric wire body, the components such as the fastener 6 do not need to be adjusted, and the wiring speed can be faster; the second type of the wire can be used in the use situation with high requirements on the stability of the wire body, so that the wire cannot loosen in the use process.

In addition, it should be noted that the elastic wire fixing mechanism 3 is conductive, that is, when the electric wire body is mounted on the elastic wire fixing mechanism 3, no matter where the elastic wire fixing mechanism 3 is located in the first conductive portion 201, the electric current can be conducted.
