The utility model belongs to an integrally formed insulating material tool, which comprises an operating handle, a frame, a rigid insulating material and a fully-wrapped insulating soft material, wherein the handle is provided with a prestressing device for tightly pressing the frame to tightly cover a shielding device and wrap a shielded object, and the frame is provided with a prefabricated bent grabbing part.

The utility model has the beneficial effects that:

1. the electric power overhaul personnel only contact the handle, and the shielding measures are carried out on the electrified part through the handle, so that the electric power overhaul personnel have more operating distances and more safety distances compared with the shielding of the original insulating blanket cladding and normal insulator shielding cover. (the industry stipulates the safe distance: 0.4 meters relatively, 0.6 meters apart);

2. according to the utility model, the target insulator is wrapped by opening and closing the handle, and compared with the traditional method of folding and wrapping the insulator by using an insulating blanket, fixing the blanket clamp and manually opening and closing the insulator shielding cover, the method is more efficient and labor-saving;

3. the utility model belongs to an integrated forming device, and compared with an insulating blanket, the utility model also needs to be provided with a blanket clamp, and compared with the existing insulator shielding cover, the placement is more convenient, and the device can directly clamp the edge of the insulating outer arm, and is convenient to carry.
