The adjusting handle 7 is fixedly connected to the bottom outer wall of the gear rack 11, and the fixing handle 8 is fixedly connected to the other end of the bottom of the clamping seat 5.

[0036] like Figure 3 and Figure 4 As shown, the rotating groove has multiple sliding holes arranged in a circle. The extension rod 15 is slidably connected to the inner wall of the sliding hole, and one end of the extension rod 15 is fixedly connected to the outer wall of the elastic ring 6.

[0037] A sliding seat 14 is fixedly connected to the sliding hole in the axial position. An extension rod 15 is slidably connected to the inner wall of the sliding seat 14.

The gear ring 10 will then drive the bevel gear 13 and the lead screw 16 to rotate through the bevel gear 13 meshing with it. The rotation of the lead screw 16 will drive the extension rod 15 threaded on it to slide in the sliding seat 14, and drive the elastic ring 6 to move and unfold. The wire to be tested is placed in the elastic ring 6. At this time, release the adjustment handle 7. The spring force of the reset spring 12 will drive the gear rack 11 to move in the opposite direction, and then drive the gear ring 10 to rotate in the opposite direction. The extension rod 15 will then drive the elastic ring 6 to return to its original position and clamp and fix the wire through the conductive sheet 9.
