Description

Technical Field

[0001] The invention relates to the technical field of power wiring, in particular to a tool pliers for power wiring and a use method thereof. Background Art

[0002] The installation of grounding clamps is a special operation. The connected wires or copper bars are usually erected in the air above 4 meters. It is necessary to use a sufficiently long insulating top rod to lift the wiring tool to the height of the wires or copper bars for remote operation. At present, the industry generally uses a grounding clamp that is assembled and disassembled by screwing. There are two major problems with this clamp during use.

[0003] 1. The success rate of one-time clamping is low. In the clamping process, the existing wire clamp transmits the rotational force to the clamp head by twisting the insulating handle, driving the screw in the clamp head to rotate, and finally tightening the clamp plate to clamp the wire or the copper busbar. This installation method cannot install a fixing device at the clamp head, resulting in the clamp head moving with the rotation of the handle during the twisting process of the insulating handle, resulting in the inability to accurately clamp the wire or copper busbar.

[0004] 2. Difficult to disassemble. When the existing wire clamp needs to be disassembled, the insulated handle is screwed in the opposite direction to drive the screw inside the clamp to rotate, so as to loosen the clamp. However, in actual operation, when the wire clamp is clamped, the friction between the clamp and the wire can ensure that the screw rotates smoothly while the wire clamp is not loose. However, when the clamp is loose but the opening is not open enough to detach from the wire, the friction between the clamp and the wire is weakened, and the stability of the clamp cannot be guaranteed. The clamp will move along the wire as the insulating handle rotates, which is not only inconvenient, but also poses a safety hazard during the disassembly process. Summary of the invention

[0005] The object of the present invention is to provide a tool pliers for power wiring and a method of using the same to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0016] S2, insert the insulating ejector rod with ejector pin into the casing, and the magnet in the casing will attract the insulating ejector rod;

[0017] S3, pull the handle to make the upper clamping plate detach from the lower clamping plate, then rotate the support plate so that the support plate rests on the limit rod, at this time pull the tension spring and insert the pull pin into the ring at the end of the tension spring, and make one end of the pull pin contact with the baffle in the spring compartment, and the other end is inserted into the limit groove, then place the cable to be connected to the main line between the lower clamping plate and the upper clamping plate, at this time use the insulating top rod to lift the entire wiring tool, and connect the cable to be connected to the main line with the main line, then move the wiring tool to make the main line contact with the support plate, and push the support plate away from the limit rod, at this time under the action of the tension spring, the upper clamping plate quickly descends to clamp the cable for access;

[0018] S4, use the pin at the end of the insulating push rod to push the bowl-shaped plug upward, and the bowl-shaped plug drives the unlocking lever to move upward in a scissor-like manner along the installation rods on both sides of the casing. At this time, the end of the unlocking lever tends to move downward. At this time, the pull pin is pulled out of the limit groove through the wire rope, and then the ring at the end of the tension spring slides off the pull pin, and then the tension spring is in a relaxed state.

During the disassembly process, only the bowl-shaped plug is supported so that the unlocking lever and the wire rope drive the pull pin to separate from the tension spring. At this time, the upper and lower clamping plates are in a loose state, thereby facilitating clamping and disassembly. BRIEF DESCRIPTION OF THE DRAWINGS
