Problems solved by technology
When the diameter of the wire is small, it can be completed with bare hands by the construction personnel, but when the diameter of the power cable reaches about 240 mm, the cable rigidity is relatively high, and it is difficult to make the arc with bare hands. Due to the lack of special power cable bending These tools have seriously affected the quality and efficiency of arc-shaped wire bending. If the existing non-professional tools are used for production, the production is difficult, and it is easy to cause damage to the insulation layer of the power cable, which seriously threatens the safe operation of the power supply line.

Embodiment Construction
[0015] Such as figure 1 , 2 As shown in and 3, a live wire bender for power lines includes a wire bending card, a connecting pin 1 and a handle, and the wire bending card is composed of a card body 2, a wire slot, a pin hole 3 and a handle hole 4. 2. It is composed of at least two layers of insulating materials reliably connected. The wire groove is located at the front of the card body 2 and embedded in the card body 2. The wire groove is composed of a straight groove 5, an arc groove 6 and a groove wall 7. The groove wall 7 is connected to the card body. Body 2 is connected in an arc. The pin hole 3 and the handle hole 4 are located at the end of the card body 2. The pin hole 3 is perpendicular to the handle hole 4 and runs through the card body 2. The connecting pin 1 is installed in the pin hole 3, and the handle is connected to the bent wire card through the connecting pin 1. The handle is made of a sleeve 8 and a handle arm 9, and the inner wall of the radial section o...

The invention discloses an electrified wire bending device of an electric power circuit, comprising a wire bending card, a connection pin and a handle. The wire bending card consists of a card body, a line slot, a pinhole and a handle hole, the card body is formed by reliably connecting at least two layers of insulation materials, the line slot is arranged at the front part of the card body and is embedded in the card body, the pinhole and the handle hole are arranged at the distal end of the card and vertically penetrate through the card body, the connection pin is arranged in the pinhole, and the handle is connected with the wire bending card through the connection pin. The electrified wire bending device disclosed by the invention has the advantages of simple, light and convenient structure, high insulation grade, convenience, safety and reliability for carrying and using, can be widely suitable for bending cables with various diameters and does not cause any damage on insulating layers of the electric power circuit.
Description
technical field [0001] The invention relates to a power line live wire bender, which belongs to the field of electric construction tools. Background technique [0002] In the construction of power cable erection, it is often necessary to bend the power cable into an arc shape, so as to ensure reliable connection between the power cable and supports such as insulating ceramic bottles or ceramic columns. When the diameter of the wire is small, it can be completed with bare hands by the construction personnel, but when the diameter of the power cable reaches about 240 mm, the cable rigidity is relatively high, and it is difficult to make the arc with bare hands. Due to the lack of special power cable bending These tools have seriously affected the quality and efficiency of arc-shaped wire bending. If the existing non-professional tools are used to make the production, the production is difficult, and it is easy to cause damage to the insulation layer of the power cable, which s...
