Technical Field
The invention relates to the technical field of metal detection, in particular to a handheld metal detector.
Background
In the exploration equipment, a handheld metal detector is used for detecting underground mineral products, the principle is that according to the electromagnetic induction principle, a coil which is communicated with alternating current is used for generating an alternating current changing magnetic field, the alternating current changing magnetic field can generate induced eddy current in the detected metal, the eddy current can generate a magnetic field, the magnetic field can influence the original magnetic field in turn, and the detector is triggered to sound so as to search mineral substances, but the existing handheld metal detector always has some problems:
the existing hand-held metal detector needs to keep a certain distance with the ground in the using process, which requires a person to hold the detector all the time, but the detector can be scratched due to the protrusion of the detector and the ground caused by negligence of an operator, so that the detector is damaged, the continuous working time of the person can be seriously influenced if the person holds the detector all the time, arms are easily tired, the efficiency is not improved, particularly under the underground mineral exploration condition, not only underground mineral is explored, but also peripheral walls are detected, so that if the traditional hand-held metal detector is used, the distance between the detector and the wall is more difficultly controlled, the person is more easily tired, and the existing detector does not have the function of marking the position of detected metal no matter whether the underground mineral is explored or the mineral is explored, the detected position must be marked manually by lime, so that the marked position is not accurate, but the mark on the ground is easy to be blurred, thereby reducing the working efficiency of exploration.
