AI Technical Summary
In the measurement of resistance of grounding flat iron, there is often a gap between the test wire and the grounding flat iron, which leads to inaccurate measurement results. Furthermore, it is difficult to fix the test wire effectively when measuring on a wall, resulting in angular error.
An adaptive adjustment mechanism was designed, including components such as mounting parts, placement rods, racks, gears, ratchet wheels, and pawls. The adaptive adjustment of the test lead is achieved through gear linkage, and combined with a strong magnet fixing device, it ensures that the test lead is in perpendicular contact with the grounding flat iron.
This improves the accuracy of grounding flat iron detection, avoids measurement errors, and ensures close contact and verticality between the test wire and the grounding flat iron.
