Install grounding wire clamps at the copper-aluminum transition wire clamps of transformer and switch leads
By adding a stop clamp to the U-shaped wire clip, designing an inverted U-shaped structure and reset torsion spring, the problem of heavy pulling when installing the grounding wire is solved, resulting in damage to the copper-aluminum transition wire clip, and the effect of easily installing the grounding wire without damaging the wire clip is achieved.

AI Technical Summary
Technical Problem
In the prior art, a large tension is required when installing a grounding wire, which can easily lead to damage or breakage of the copper-aluminum transition wire clamp, affecting the operation safety of the line.
Method used
The stop clamp is added on the basis of the existing U-shaped wire clamp, designed as an inverted U-shaped structure. The double-toned wire clamp is easily installed through reset torsion springs and stop clamps to avoid damage to the copper-aluminum transition wire clamp.
Benefits of technology
The installation of the grounding wire can be easily completed with a small pulling force, avoiding damage to the copper-aluminum transition wire clamp and improving operation convenience and safety.

Abstract
The invention discloses a wire clamp for installing a grounding wire at a copper-aluminum transition wire clamp of a transformer and a knife switch lead wire. The wire clamp comprises a wire clamp body and a wire clamp double tongue. The wire clamp body is an inverted U-shaped structure, a middle stopper is arranged on the top, strip-shaped through holes are arranged on both sides of the middle stopper, the wire clamp double tongues are two and are in an arc-shaped structure, one end of the wire clamp double tongue is hinged to the wire clamp body, and the other end of the wire clamp double tongue passes through the wire clamp body through the strip-shaped through hole, and a reset torsion spring is arranged between the wire clamp double tongue and the wire clamp body; when the grounding wire is installed on the conductor of the copper-aluminum transition wire clamp of the transformer lead wire, because the double tongues of the wire clamp are held open by a semicircular positioning stop fixture, and the double-tongue double-mouth calibers are larger than the diameter of the conductor, as long as the conductor slightly touches the semicircular positioning stop fixture to destroy the positioning stop condition, the grounding wire can be easily installed without causing any external force damage to the copper-aluminum transition wire clamp of the transformer.
