[0001] The invention relates to the technical field of electric tools, in particular to an insulating rod method live lead clamp. Background Art

[0002] The popular insulated rod method live lead clamps on the market are currently mostly J-type or K-type wire clamps, which are mainly composed of two parts, one part is two J elements with wedges to fix the lead, and the other part is a bolt to tighten; Through many practices of live connection, it was found that this type of wire clamp has the following three problems: first, there are model restrictions for different lead wires, and the fastening screws between different models of wire clamps are not universal; second, during the fastening process, the lead wire or the main wire is often stuck in the middle of the wedge block, resulting in the screw being unable to be fastened, resulting in live connection failure; third, during the fastening process, a lead wire operating rod needs to be used to hold the wire, and poor cooperation of the operator can easily cause the lead wire to fall off, affecting the personal safety of the operator. Therefore, the present invention proposes an insulating rod method live connection wire clamp to solve the problems existing in the prior art. Summary of the invention

[0003] In view of the above problems, the present invention proposes an insulating rod method live wire clamp, which only needs to be operated with a shooting gun rod during connection, avoiding the need for pole climbing workers to use a wire holding rod for operation, greatly saving manpower, increasing operation speed and improving operation safety.
