[0038] When the staff needs to detect the switch cabinet, the locking mechanism 8 can be used to cancel the limiting of the rotating rod 411 in advance, and then the two test pens 415 are taken out from the interference fit clamping ring frame 6. Since the two test pens 415 are connected to the first wire harness 414 at the ends, and the wire harness is wound around the two wire reels 413 in the middle of the rotating rod 411, the pulling force caused by the staff taking the test pen 415 will rotate the rotating rod 411 and the two wire reels 413, thereby achieving the relaxation of the test pen 415 and the connected wire harness, so as to adjust the measurement position of the test pen 415 on the switch cabinet.

The length of the second wire harness 47 only needs to be enough for the above movement, and when winding, only the reverse operation is needed. It is portable and practical. Secondly, when the rotating rod 411 and the fixed gear 81 are rotated to the appropriate angle, the staff can slowly loosen the pull block 84, so that it is inserted into the alignment tooth groove around the gear 81 with the guide rod 85 and the clamping block 87 cooperating with the movable groove 86 in the middle of the fixed mounting block 82 under the reset of the first reset spring 83, thereby achieving the fixation of the rotating rod 411 and the wire reel 413, and locking the adjustment length of the first wire harness 414.
