[0002] The maintenance and repair of power distribution lines mainly include regular inspections of the line equipment status, clearing tree obstructions along the line, handling broken strands or wear of conductors, inspecting and tightening connection components, replacing damaged insulators or hardware, measuring grounding resistance and repairing grounding devices, repairing distribution transformers and switchgear, testing line insulation resistance, preventing external damage, and eliminating equipment overheating or discharge defects. In line maintenance work, it is often necessary to fix low-voltage grounding wires, broken strands of conductors, and terminals to prevent equipment from becoming energized and causing injury to operators.

[0003] In existing technologies, wire ends are often clamped using insulated gloves or insulated pliers, which poses a high risk when operated by hand. Insulated pliers are inconvenient to adjust and cannot clamp and fix wires of different sizes. In addition, the operating distance is short, which increases the risk factor. They are also inconvenient to use for power testing and closing operations. Therefore, a convenient wire end fixing device for the maintenance of power distribution automation lines is proposed.

A thrust seat 5 is vertically slidably installed inside the guide cylinder 2. A spring 11 is provided between the thrust seat 5 and the bottom surface of the guide cylinder 2. Specifically, the spring 11 is housed inside the guide cylinder 2, and the top of the spring 11... The spring 11 is inserted into the countersunk hole on the bottom surface of the thrust seat 5. The bottom end of the spring 11 abuts against the inner bottom surface of the guide cylinder 2. Both ends of the thrust seat 5 extending out of the mounting cylinder 1 are hinged to connecting rods 9. Specifically, the connecting rods 9 are H-shaped, and both ends of the connecting rods 9 are hinged by hinge shafts. The end of the guide cylinder 2 away from the mounting cylinder 1 is detachably connected to a support 6. The two ends of the support 6 are respectively hinged to a first gripper 7 and a second gripper 8.

The first gripper 7 and the second gripper 8 are hinged and positioned via the support 6. The bottom ends of the first gripper 7 and the second gripper 8 are connected to the end of the thrust seat 5 via the connecting rod 9. Then, under the action of the spring 11, the thrust seat 5 pushes... The push seat 5 drives the first gripper 7 and the second gripper 8 to rotate in opposite directions around the end of the support 6, thereby separating and opening the first gripper 7 and the second gripper 8 to facilitate clamping the wire. The handle 13, in conjunction with the pressure handle 18, drives the pull rope 12 to pull the push seat 5 in the opposite direction. The push seat 5 compresses the spring 11, thereby driving the first gripper 7 and the second gripper 8 to rotate in opposite directions around the end of the support 6. The first gripper 7, the second gripper 8, and the support 6 work together to clamp and fix the wire end. This not only makes it easy to carry, but also allows for easy adjustment of the clamping size of the first gripper 7 and the second gripper 8 according to the wire size. Furthermore, it makes it easier to apply force during clamping and provides higher stability.

[0016] In this embodiment, the outer wall of the guide cylinder 2 is further provided with a guide groove 3 that is slidably connected to the two shaft sections of the thrust seat 5.

By providing the protective sleeve 14 on the outside of the handle 13, a gripping area for the operator is formed, which can effectively prevent slippage and improve the stability of use.

[0018] In this embodiment, the handle 13 is further provided with an insulating sleeve 15. Specifically, the insulating sleeve 15 is tightly fitted to the outer wall of the handle 13. The insulating sleeve 15 is made of silicone or rubber. The two ends of the insulating sleeve 15 abut against the two ends of the protective sleeve 14. Specifically, the insulating sleeve 15 is located inside the protective sleeve 14, so that the user can be insulated and protected by the insulating sleeve 15, thereby improving the safety of operation.

[0019] In this embodiment, the inner bottom surface of the thrust seat 5 is further detachably connected to a guide rod 10 that passes through the spring 11. The bottom end of the guide rod 10 is slidably connected to one end of the guide cylinder 2 that extends into the mounting cylinder 1. Specifically, the bottom end of the guide rod 10 is fitted with a shaft hole in the inner bottom surface of the guide cylinder 2. The end of the guide rod 10 that extends into the mounting cylinder 1 is detachably connected to the end of the pull rope 12 that is away from the handle 13. Specifically, both ends of the pull rope 12 are provided with connectors. The connector at the top of the pull rope 12 is threadedly connected to the end of the guide rod 10 that extends into the mounting cylinder 1. Thus, the guide rod 10 is slidably connected to the inner bottom surface of the guide cylinder 2. The guide rod 10 further guides the sliding installation of the thrust seat 5, improving the stability of the thrust seat 5. The guide rod 10 also extends downward to facilitate the connection of the pull rope 12.

[0020] In this embodiment, a traction rod 16 is slidably connected inside the handle 13. One end of the traction rod 16 extending into the mounting cylinder 1 is detachably connected to the end of the pull rope 12 away from the guide cylinder 2. Specifically, the connector at the bottom of the pull rope 12 is threadedly connected to the end of the traction rod 16 extending into the mounting cylinder 1. A counter-pull rod 19 is hinged between the end of the pressure handle 18 away from the handle 13 and the extended end of the traction rod 16. Thus, the traction rod 16 can cooperate with the handle 13 to pull... The rod 16 further pulls the pull rope 12, and the pull rod 16 and the end of the extension and the pressure handle 18 away from the handle 13 are hinged by the counter-pull rod 19. Then, by holding the handle 13 and the pressure handle 18, the pressure handle 18 is deflected towards the handle 13. The pressure handle 18 cooperates with the counter-pull rod 19 to stretch the pull rod 16 outward. Then, the pull rope 12 and the guide rod 10 counter-pull the push seat 5 to compress the spring 11. The first clamp 7 and the second clamp 8 clamp and fix the wire end.

[0021] In this embodiment, the end of the traction rod 16 extending out of the handle 13 is detachably connected to a corner seat 17. Specifically, the corner seat 17 is in the shape of a right angle or an obtuse angle, with one end threadedly connected to the extended end of the traction rod 16. The end of the corner seat 17 facing away from the traction rod 16 is hinged to the end of the counter-pull rod 19 facing away from the pressure handle 18. By setting the corner seat 17 at the extended end of the traction rod 16, the counter-pull rod 19 can be hinged to the traction rod 16, making disassembly and maintenance more convenient.

[0022] The working principle of this utility model is as follows: When it is necessary to clamp the wire, the clamping area formed by the first clamp 7 and the second clamp 8 covers the wire end. By holding the handle 13 and the pressure handle 18, the pressure handle 18 is deflected towards the handle 13. Through the pressure handle 18 and the counter-pull rod 19, the traction rod 16 is stretched outward. Then, through the pull rope 12 and the guide rod 10, the push seat 5 is pulled back to compress the spring 11. The push seat 5 pulls the connecting rod 9, which deflects the first clamp 7 and the second clamp 8 towards each other. Then, through the first clamp 7 and the second clamp 8 and the support 6, the wire end is clamped and fixed. By pressing the pressure handle 18, the clamping and fixing of the wire end can be maintained at all times.
