The staff turns on the metal detector and performs a sensitivity test before use. When the No. 1 coil 10 inside the detection disk 1 has a weakened metal detection ability, the staff presses the button set at the upper end of the support rod 2 to make the driving device work, so that the threaded rod 16 connected to its output end rotates, and the threaded rod 16 is threadedly connected to the vertical plate 18. A sleeve 1601 is provided between the threaded rod 16 and the clamp 13, so that the threaded rod 16 can move horizontally, thereby driving the clamp 13 to move horizontally. By providing the shrinking coil 12, the shrinking coil 12 can be squeezed and shrunk. When the clamp 13 moves horizontally, the shrinking coil 12 is squeezed and shrunk, so that the shrinking coil 12 is exposed to the detection surface, thereby increasing the number of coils inside the detection disk 1, thereby improving the sensitivity of the metal detector. By providing an isolation plate 11, and the side close to the first coil 10 is the detection surface, and the isolation plate 11 is a circular ring with the diameter of the first coil 10, when the shrinking coil 12 is squeezed and shrunk, it will be exposed to the detection surface, thereby increasing the number of coils in the detection disk 1 and improving its sensitivity.

[0026] like Figure 1-Figure 4 As shown, a No. 1 driving device 17 is fixedly installed at one end of the threaded rod 16 away from the clamp 13, an electric telescopic rod 14 is fixedly installed on the inner wall of the clamp 13, a sliding block 15 is fixedly installed at one end of the electric telescopic rod 14 away from the clamp 13, a sleeve 1601 is rotatably installed on one side surface of the clamp 13, the sleeve 1601 is threadedly screwed and connected with the threaded rod 16, the sliding block 15 is slidably connected with the clamp 13, and there are two electric telescopic rods 14. The staff starts the No. 1 driving device 17, so that the No. 1 driving device 17 works, and the output end of the No. 1 driving device 17 is connected to the threaded rod 16, and the threaded rod 16 is connected to the vertical plate 18 and the sleeve 160. 1 is screwed together, and the sleeve 1601 is rotatably connected with the clamp 13, so that when the No. 1 driving device 17 is working, the threaded rod 16 moves horizontally, so that the clamp 13 moves horizontally, so that the two clamps 13 can squeeze the shrinking coil 12 to make it be squeezed and shrunk. When the shrinking coil 12 needs to be restored to its original position, the electric telescopic rod 14 is turned on to make the sliding block 15 slide to the outside of the clamp 13, so that the two sliding blocks 15 clamp the shrinking coil 12, and then the No. 1 driving device 17 is turned on to make the threaded rod 16 move with the clamp 13 toward the No. 1 driving device 17, so that the shrinking coil 12 is restored to its original position. Example

[0027] A metal detector calibration device, such as Figure 1-Figure 2 As shown, at least two mounting blocks 8 are fixedly installed on the upper end of the detection disk 1, and the mounting blocks 8 are threadedly screwed with the support rod 2 by bolts 9.

The No. 2 driving device 6 is fixedly installed with a rotating shaft 601, and the rotating shaft 601 is fixedly installed with a gear plate 5. By setting the mounting blocks 8 to be threadedly screwed with the support rod 2 by bolts 9, it is more convenient for the staff to carry out detection.

At this time, the staff turns on the No. 2 driving device 6, and the rotating shaft 601 is fixedly installed on the output end of the No. 2 driving device 6, so that when the No. 2 driving device 6 is turned on, the rotating shaft 601 rotates, and at the same time, the rotating shaft 601 is fixedly connected with the gear plate 5, so that the gear plate 5 rotates.

[0028] like Figure 1-Figure 2 As shown, the gear plate 5 is meshedly connected with the gear plate 4, the gear plate 4 is fixedly connected with the auxiliary rod 3, the auxiliary rod 3 extends to the outside of the support rod 2, and the auxiliary rod 3 is fixedly installed with a balance plate 7 at one end away from the support rod 2. The balance plate 7 is located in the middle above the detection plate 1, and the balance plate 7 is used for balancing and resetting the detection plate 1. The gear plate 5 is meshedly connected with the gear plate 4, so that the gear plate 4 moves, thereby driving the auxiliary rod 3 to move. At the same time, the balance plate 7 is fixedly installed at one end of the auxiliary rod 3 away from the support rod 2, so that when the auxiliary rod 3 moves out of the support rod 2, the balance plate 7 is driven to move, so that the balance plate 7 touches the detection plate 1, so that the detection plate 1 is balanced and reset.

[0029] Working principle: The staff turns on the metal detector and performs a sensitivity test before use.

When the clamp 13 moves horizontally, the shrinking coil 12 is squeezed and shrunk, so that the shrinking coil 12 is exposed to the detection surface, thereby increasing the number of coils inside the detection plate 1, thereby improving the sensitivity of the metal detector, and by setting an isolation plate 11, and close to the No. 1 coil 10 One side is the detection surface, and the isolation plate 11 is a circular ring with the diameter of the No. 1 coil 10, so that when the shrinking coil 12 is squeezed and shrunk, it will be exposed on the detection surface, thereby increasing the number of coils in the detection disk 1 and improving its sensitivity. At the same time, the staff turns on the No. 2 driving device 6, and the output end of the No. 2 driving device 6 is fixedly installed with a rotating shaft 601, so that when the No. 2 driving device 6 is turned on, the rotating shaft 601 rotates, and the rotating shaft 601 is fixedly connected to the gear plate 5, so that the gear plate 5 rotates, and the gear plate 4 is meshed and connected by the gear plate 5, so that the gear plate 4 moves, thereby driving the auxiliary rod 3 to move, and at the same time, the auxiliary rod 3 is fixedly installed with a balance plate 7 at one end away from the support rod 2, so that when the auxiliary rod 3 moves out of the support rod 2, it drives the balance plate 7 to move, so that the balance plate 7 touches the detection disk 1, so that the detection disk 1 is balanced and reset.
