Description

Technical Field

[0001] The utility model relates to an underground metal detector, belonging to the technical field of electronics and detection. Background Art

[0002] Underground metal detectors are widely used in mineral exploration, archaeological excavations, security inspections, and scrap metal recycling. Their basic principle is electromagnetic induction, emitting high-frequency electromagnetic waves and receiving reflected signals from metal objects to locate and identify metal targets. However, existing underground metal detectors have issues with battery replacement and display module viewing angle adjustment, which affect user experience and detection efficiency.

[0003] Traditional underground metal detectors typically feature fixed display modules, preventing users from adjusting the viewing angle of the display screen to suit their needs. This can lead to unclear displays and inconvenient operation when using the detector in varying lighting conditions or for users of varying heights. Furthermore, traditional underground metal detectors typically feature a fixed battery compartment, requiring tools or complex procedures to open the battery compartment cover when replacing batteries. This not only increases operational complexity but can also lead to problems such as damage to the cover or poor battery contact. Utility Model Content
