Description

Technical Field

[0001] The utility model relates to the technical field of resistance testers, in particular to a novel resistance tester clamp structure with high stability. Background Art

[0002] Grounding resistance refers to the resistance of the grounding body buried underground and the scattered resistance of the soil. It is usually measured using a grounding resistance meter (or grounding resistance megohmmeter). The appearance and structure of the megohmmeter vary slightly depending on the model, but the method of use is basically the same. The measuring instrument also comes with two grounding detection rods and three wires. The clamping effect of the existing tester test clamp is poor, which makes the clamping range small and the adaptability of the clamp is poor. At the same time, the protection effect of the clamp is poor, the DC resistance cannot be fully clamped, and the operability is poor. For this reason, we propose a new resistance tester clamp structure with high stability to solve the above problems. Utility Model Content

[0007] Furthermore, a second handle is fixedly mounted on the upper end of the movable splint.

[0008] Furthermore, a first handle is fixedly installed on the left side of the sliding block.

[0009] Compared with the prior art, the utility model has the following advantages:
