[0003] Most tools have fixed-length levers that cannot be adjusted according to working height and space. In overhead line work at different heights, fixed-length levers may make it difficult for operators to accurately reach the work point, creating blind spots. At the same time, because it is inconvenient to replace the ends, wire hooks, eagle-beak wire clamps, and scissor heads all need to be equipped with fixed levers, affecting the efficiency of operation and maintenance.

At this point, the protective sleeve 22 and the end of the main rod 21 away from the fixed rod 11 are on the same plane. Then, the main rod 21 is connected to the hook upright 31 through the combined screw 39 and the combined screw hole 24. Then, the protective sleeve 22 is rotated in the opposite direction until the end of the protective sleeve 22 away from the first limiting ring 23 is in contact with the second limiting ring 38. At this point, the protective sleeve 22 covers the connection between the main rod 21 and the hook upright 31 on its inner side, protecting the connection and improving the safety of tool use.

[0036] The working principle of this utility model is as follows: Before use, carefully inspect all components, clean the sliding groove 12 of the fixing rod 11, the combined screw hole 24, and the combined screw 39 to ensure that there are no foreign objects or oil stains affecting the connection effect. First, thread the protective sleeve 22 to the combined main rod 21. Unscrew the protective sleeve 22 from the top of the combined main rod 21 until the protective sleeve 22 is in contact with the first limiting ring 23.

When using the combination assembly 2, insert the combination screw 39 into the combination screw hole 24 and rotate it until the hook upright 31 is in contact with the main combination rod 21, thus achieving the combination connection between the main combination rod 21 and the hook upright 31. After completing the connection between the hook upright 31 and the main combination rod 21, rotate the protective sleeve 22 in the opposite direction, allowing it to slide downwards along the main combination rod 21 and the hook upright 31 until the end of the protective sleeve 22 away from the first limiting ring 23 is in contact with the second limiting ring 38. At this point, the protective sleeve 22... The connection between the main rod 21 and the hook rod 31 is completely fitted inside, achieving insulation protection and waterproof sealing of the connection. Hold the handle 18 and rotate the threaded rod 17 clockwise. During the rotation, the threaded rod 17 interacts with the combined screw hole 24, driving the main rod 21 to slowly extend along the axial direction of the limiting rod 15. Due to the cooperation between the guide groove and the limiting rod 15, the main rod 21 will not rotate and will always maintain linear motion. When performing live work, the C-shaped arc structure and anti-disengagement part of the first hook 36 and the second hook 37 can be used to complete the hooking, fixing or transferring of wires, tools or objects. The hook assembly 3 is described as one end of the combined tool. The combined assembly 2 can also be used in combination with the beak clamp and the scissor head.
