[0029] The support plate 1 has several columns 10 around its bottom. One end of each column 10 is fixedly connected to the support plate 1, and the columns 10 provide support for the support plate 1. The other end of each column 10 is fixedly connected to a clamping device mounting plate 11. The clamping device mounting plate 11 can be fixedly connected to the mounting platform 12. The mounting platform 12 is fixedly mounted at the bottom of the clamping device mounting plate 11, and the mounting platform 12 can support the present invention. Clamps 13 are provided at the center lines of both ends of the clamping device mounting plate 11 on the mounting platform 12, and the clamps 13 can fix and clamp the two ends of the magnetic rod 14.

[0030] The chuck 13 includes several abutment blocks 15 and a mounting base 16. The mounting base 16 is fixedly mounted on the mounting platform 12, and the several abutment blocks 15 can abut the end positions of the magnetic rod 14.

[0031] Working principle:

[0032] In use, the bottom of the magnetic rod 14 is placed against the fixing block 501 of the present invention. At this time, the strong magnetism of the magnetic rod 14 causes the iron block 903 to come close to the magnetic rod 14. The iron block 903 coming close to the magnetic rod 14 drives the power source connecting rod 902 to move. When the power source connecting rod 902 moves, the power source support block and connecting rod 904 fixedly connected to it slide along the through groove 8. The connecting rod 904 slides through the turntable 702 to drive the rotating shaft 701 to rotate in the mounting hole 6. When the rotating shaft 701 rotates, the second rope fixing rod 703 fixed to the rotating shaft 701 also rotates. The second rope rod provides the first rope fixing rod 404 with a moving force through the rope. When the fixed rod 404 is under force, the fixed component 4, which is fixedly connected to the first rope fixed rod 404, is under force, so that the upright plate 402 can abut against one side of the magnetic rod 14, causing the magnetic rod 14 to rotate so that the strongest magnetic circuit of the magnetic rod 14 is aligned with the detection magnetic circuit. Then, the clamp 13 is activated to clamp both ends of the magnetic rod 14 and fix the magnetic rod 14. During this process, when the fixed component 4 moves, the slide table 201 moves along the slide rail 202. The tension rod 502 extends out of the through hole 505, and the spring 503 is compressed under force. When the test is completed, the clamp 13 is released and the magnetic rod 14 is removed, causing the spring 503 to lose force. The spring 503 rebounds and drives the fixed component 4 back to its original position.
