Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention mainly relates to connecting the ends of the electric wires at a predetermined relative interval when connecting two electric wires by crimping or soldering through a connecting sleeve. This invention relates to an electric wire gathering tool for connecting electric wires that is used to draw and hold electric wires in position.

<Prior art> Conventionally, in order to connect two electric wires by crimping or soldering through a connecting sleeve, one of the workers grasps the two electric wires to be connected.
While maintaining the position of inserting the bare wire section into the connection sleeve, one of the workers presses the connection sleeve with a pressure tool to make the crimped connection. Similarly, the bare wire portions are held in a facing position or in a parallel contact position, and another worker performs the soldering work.

Therefore, conventional manual connection of electric wires of this type usually involves two people working together.
In particular, in cases where the electric wire is already suspended on a utility pole or on the roof of a required building, or where one of the electric wires is suspended, two-person work is essential.

<Problems to be Solved by the Invention> Therefore, in the past, there were problems in that work efficiency was poor and two-person work on utility poles was dangerous.

Therefore, in order to solve these conventional problems, the present invention aims to develop a work tool that allows one person to perform this type of wire connection work efficiently and with relatively little danger. We hereby propose a work tool that has achieved this goal.
