Description

Technical Field

[0001] The utility model relates to the technical field of detonator detection, in particular to a detonator detection device with multiple protection structures. Background Art

[0002] In order to ensure the quality of detonators during blasting operations, necessary inspections are required before loading. Detonators are easily affected by external electricity and stray currents and are high-risk pyrotechnics.
