Description

Technical Field

[0001] The utility model belongs to the technical field of bracelet detection, and in particular relates to a hole detection device. Background Art

[0002] At present, when testing hollow gold bracelets, it is generally impossible to accurately determine whether the hollow gold bracelet contains silver or other non-gold materials in a non-destructive manner. Therefore, testers often use a steel needle to drill a micro hole in the inner ring of the hollow gold bracelet, and then use a magnifying glass to observe the inside of the hollow gold bracelet to determine whether it contains other non-gold materials. However, when testing, the tester needs to hold the hollow gold bracelet with one hand and pinch the steel needle with the other hand, and it is very inconvenient to rotate and adjust the hollow gold bracelet with one hand, which is not conducive to the tester's testing. Utility Model Content

[0003] In order to overcome the defects of the prior art, the utility model provides a hole detection device which can conveniently detect hollow gold bracelets.

[0019] The beneficial effects of adopting the above technical solution are: since one end of the first plate body is hinged to the second plate body, the first plate body can be flipped around the hinge point with the second plate body, and the angle adjustment component can change the deflection angle of the first plate body, so that the orientation angle of the steel needle changes, thereby adjusting the orientation of the steel needle when drilling a hole in the hollow gold bracelet to avoid limiting the drilling field of view due to the hollow gold bracelet blocking the light source.

[0020] In one embodiment, the angle adjustment assembly includes two connecting rods and strip grooves arranged on both sides of the first plate body, the length direction of the strip groove is the same as the length direction of the first plate body, and the upper end of the strip groove is evenly connected with a plurality of slots along the length direction; one end of the connecting rod is hinged on the second plate body, and the other end of the connecting rod is provided with a protrusion slidably connected to the strip groove and the plurality of slots.
