A retractable clamp current meter

Abstract

The invention discloses a retractable clamp ammeter, which relates to the technical field of clamp ammeters. Two clamp heads are arranged on the top of the ammeter body, and the clamp heads include built-in clamps arranged in and in the lower clamp , the upper clamp arranged on the built-in clamp, the telescopic rod for making the clamp head telescopic and the clamp head telescopic adjustment assembly, one end of the upper clamp is provided with a mounting groove, and one end of the telescopic rod is telescopic with the clamp head The adjustment assembly is connected, and a trigger is installed on the upper side of the ammeter body to link with a clamp head. The present invention performs synchronous expansion and contraction or independent expansion and contraction processing on the two clamp heads according to the needs of use. Rotate the telescopic rod as the center, so that the telescopic rod and the installation groove are connected together, that is, the telescopic rod extends into the installation groove and is connected together, so that the lifting rod can be adjusted by pushing the push block to slide the two clamp heads at the same time. Synchronous scaling processing.

Description

technical field [0001] The invention relates to the technical field of clamp ammeters, in particular to a retractable clamp ammeter. Background technique [0002] A clamp ammeter is a combination of a current transformer and an ammeter. The iron core of the current transformer can be opened when the wrench is squeezed; the wire through which the measured current passes can pass through the opening of the iron core (that is, the pliers head) without cutting off, and the iron core is closed when the wrench is released. The clamp meter can change different ranges by shifting the gear of the switch. When using the clamp ammeter to detect the current, it is necessary to clamp a wire under test (that is, open the clamp head and clamp a wire) for detection. . [0003] The existing clamp ammeter cannot extend and shorten the clamp head during use, which has limited performance, and it is inconvenient to independently or synchronously expand and contract the clamp head according to...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies of the above-mentioned prior art, the purpose of the present invention is to provide a retractable clamp ammeter, which solves the problem that the existing clamp ammeter proposed in the above background technology cannot be clamped during use. The head is stretched and shortened, which has limited performance, and it is inconvenient to independently or synchronously stretch the pliers according to the needs of use.
