when the first support and the second support rotate, the opening of the first support points towards the opening of the second support.

The shape of the first supporting piece and the second supporting piece is designed to be C-shaped in the longitudinal section, so that the through ground wire is convenient to insert, and the acting force is convenient to apply to the through ground wire.

In the above tool for rapidly bending a through ground wire, as a preferred embodiment, the rotating rod is fixedly connected with the connecting plate on the first support vertically; the connecting plate on the second supporting piece is sleeved on the rotating rod.

In the tool for rapidly bending the through ground wire, as a preferred embodiment, the rotating rod is provided with an arc-shaped groove;

when the through ground wire is placed in the first supporting piece and the second supporting piece, the bending part of the through ground wire is embedded in the arc-shaped groove.

The arc-shaped groove is convenient for accurately positioning the bending part of the through ground wire.

In the above tool for rapidly bending through-ground wires, as a preferred embodiment, the distal ends of the first support member and the second support member are each coated with a shock-absorbing layer.

The shock-absorbing layer is the rubber layer, and the operator holds the shock-absorbing layer of first support piece and second support piece and is convenient for operate, reducible application to the hand.

In the above tool for rapidly bending through-ground wires, as a preferred embodiment, the length of each of the first support member and the second support member is 18-25cm.

The beneficial effects of the utility model are as follows: the tool for rapidly bending the through ground wire can rapidly bend the through ground wire, and can accurately position the bent position. The operation is simple and convenient, the construction efficiency is improved, the damage to cables is reduced, and the waste of materials is avoided.
