[0025] As an implementation method, the two clamps are divided into a first clamp 6 and a second clamp 7, one end of the first clamp 6 is hinged to one end of the second clamp 7, and the detection device further includes a connecting mechanism 8, and the other end of the first clamp 6 is detachably connected to the other end of the second clamp 7 through the connecting mechanism 8;

[0026] The connecting mechanism 8 includes: a first fixing block 81, a second fixing block 82, and a connecting piece 83; the first fixing block 81 is fixedly connected to the end of the first clamping plate 6; the second fixing block 82 is fixedly connected to the end of the second clamping plate 7; a groove 831 is provided on one side of the connecting piece 83, and the first fixing block 81 and the second fixing block 82 are both arranged in the groove 831, and the connecting piece 83 prevents the first fixing block 81 and the second fixing block 82 from being disengaged.

[0027] Through the above arrangement, the first clamping plate 6 is detachably connected to the second clamping plate 7 via the first fixing block 81 , the connecting member 83 , and the second fixing block 82 .

[0028] In the present application, when the first fixing block 81 and the second fixing block 82 are located in the groove 831, the connecting piece 83 can prevent the first fixing block 81 and the second fixing block 82 from being separated, thereby preventing the first clamping plate 6 and the second clamping plate 7 from being opened, so that the first clamping plate 6 and the second clamping plate 7 can stably clamp the wire 9; as an implementation method, the first fixing block 81 and the second fixing block 82 can be set to a semi-cylindrical structure and provided with an external thread.

The groove 831 is set as a threaded hole. After the connecting piece 83 is tightened on the cylindrical stud, the first fixing block 81 and the second fixing block 82 can be locked together.
