Power control cable peeling wrench

Abstract

The invention relates to a wrench, and aims at solving a technical problem of a current power control cable in a peeling process. The power control cable peeling wrench provided by the invention is characterized in that the wrench comprises a handle; the top of the handle is provided with a pressure head; the top of the pressure head is provided with hold-on teeth; the root of the pressure head is hinged to a hook head; the hook head is located at an inner side of the pressure rod; the interior of the hook head is provided with a polygonal hold-on plane; the gap between the pressure head and the hook head gradually becomes smaller when the pressure head and the hook head rotate relatively; an outer side surface of the pressure head is provided with a cutting blade; the edge of the cutting blade is higher than the hold-on teeth; and the edge of the cutting blade has a camber which is consistent with the arc shape of the pressure head. The beneficial effects of the invention are that the wrench is simple in structure, is convenient to operate, can quickly cut off an insulating rubber layer and an iron skin, and guarantees a flat notch.

Description

technical field [0001] The invention relates to a wrench, in particular to a wrench for cable stripping. Background technique [0002] At present, in the high-voltage power supply line, the structure of the control cable is as follows: figure 1 As shown, the copper cable core 1 is covered with an insulating rubber layer 21 to form a single control cable, and several control cables are combined and covered with moisture-proof paper 3 on the outside, and the moisture-proof paper 3 is covered with shielding copper foil 4, and the shielding copper foil 4 The outside is coated with an intermediate insulating rubber layer 22 , the intermediate insulating rubber layer 2 is coated with an iron sheet 5 , and an outer layer of insulating rubber layer 23 is coated outside the coated iron sheet 5 . When wiring control is required, the single control cable at the end of the control cable needs to be stripped. The operation is extremely difficult during the stripping operation. The three...

Problems solved by technology

When wiring control is required, the single control cable at the end of the control cable needs to be stripped. The operation is extremely difficult during the stripping operation. The three rubber layers, copper foil, and moisture-proof paper are relatively easy to remove, and the rubber layer can be used Cut off with a knife, the copper foil and moisture-proof paper are very thin and can be torn off by hand. The problem is that the iron sheet is difficult to remove

In the current operation, the outermost rubber layer is first peeled off with a knife, and then the tool is used to make a tear on the iron sheet, which is cut off bit by bit with pliers. The operation efficiency is extremely low, and the cut surface of the iron sheet is uneven. It is very easy to injure the hand during the operation, so there is an urgent need for a peeling device that is easy to operate and can significantly improve the operating efficiency.
