[0038] Working principle: In order to make the installation of the fault indicator body 3 more convenient and improve the installation efficiency, the staff first puts the fault indicator body 3 into the placement cup 1, moves the card slot 16 to the fixing mechanism 2, and the second spring 202 pushes the card pin 203 to be inserted into the card slot 16 to preliminarily fix the fault indicator body 3. At this time, the fourth spring 14 is compressed, and the initial position of the top ball 103 is located in the first positioning groove 104. The staff holds the second rubber sleeve 12 with one hand and the first rubber sleeve 11 with the other hand to push the sleeve 5 The sleeve 5 moves, and at the same time, the fixing frame 6 drives the lifting mechanism 7 to move. The rubber wheel 7012 set at one end of the pin 701 slides on the outside of the placement cup 1, so that the lifting mechanism 7 moves smoothly. When the top ball 103 enters the second positioning groove 105, the pin 701 in the lifting mechanism 7 moves under the elastic potential energy of the tension spring 702 and is pushed to the lower side of the compression spring 301. Then the staff pushes the sleeve 5 again to move, and the fixing frame 6 drives the pin 701 to move upward, and the pin 701 lifts the compression spring 301 to open , so that the compression spring 301 is lifted onto the limit rod 8, and the compression spring 301 then moves into the groove 802 on the slope block 801. When the top ball 103 enters the third positioning groove 106, the fixing frame 6 drives the pin 701 to move to the top of the compression spring 301 at this time to avoid affecting the subsequent rebound of the compression spring 301. Then the staff can assemble the fault indicator body 3 on the line. The staff aligns the line with the middle position of the two compression springs 301, and then pushes the long rod 4, so that the line presses the fault indicator body 3 into the placement cup 1. At the same time, the fault indicator body The body 3 drives the compression spring 301 to move downward, so that the compression spring 301 leaves the groove 802. At this time, the compression spring 301 rebounds and clamps the line therein, and the assembly work of the fault indicator body 3 is completed. The staff then needs to remove the installation device of the fault indicator. The staff pulls back the long rod 4 to make the fixing frame 6 drive the lifting mechanism 7 to move. When the long rod 4 is pulled back, the pin 701 on the lifting mechanism 7 will be blocked by the fault indicator body 3. Continue to pull back the long rod 4. The fault indicator body 3 pushes the lifting mechanism 7 to rotate to prevent its blocking from affecting removal.
