When the inner sliding plate 14 moves, it presses the spring 17. At this time, the position of the adjusting inner slide 6 in the fixed sleeve column 5 can be adjusted. After adjusting to the appropriate position, the pull rod 15 is released. At this time, when the card rod 24 reaches the position of the No. 1 limiting hole 11 on one side of the adjusting inner slide 6, the spring 17 resets and drives the inner sliding plate 14 and the card rod 24 to reset downward. The card rod 24 enters the No. 1 limiting hole 11 on one side of the adjusting inner slide 6, and the adjusting inner slide is adjusted. The position of the strip 6 in the fixed sleeve 5 is restricted, so that the spacing between the No. 1 contact electrode 9 and the No. 2 contact electrode 10 is adjusted. By rotating the limiting bolt 20 upward, the limiting bolt 20 leaves the No. 2 limiting hole 23 on one side of the adjusting support plate 3. At this time, the position of the adjusting support plate 3 in the connecting support plate 2 can be adjusted, and then the moving position of the No. 2 limiting hole 23 is observed through the No. 2 opening 19. The No. 2 limiting hole 23 below is re-limited and fixed by the limiting bolt 20, and the position between the connecting support plate 2 and the adjusting support plate 3 can be fixed, which is convenient for the No. 1 contact electrode 9 and the No. 2 contact electrode 10 to detect steel corrosion.

[0031] It can be understood that the utility model pulls the pull rod 15 through the pull block 16, and the pull rod 15 drives the inner sliding plate 14 and the clamping rod 24 to move, and the clamping rod 24 is separated from the No. 1 limiting hole 11, thereby completing the adjustment of the position between the inner sliding strip 6 and the fixed sleeve column 5.

[0032] See also Figures 1 to 4 A limiting slide rod 22 is symmetrically fixed to one side of the fixed plate 4, and a fixed side plate 21 is slidingly provided on the outer side of the limiting slide rod 22. One side of the fixed side plate 21 is fixed to the connecting support plate 2, and a No. 1 through hole 13 is opened on one side of the fixed sleeve column 5 to cooperate with the No. 2 contact electrode 10.
