[0029] Embodiment 1:

[0030] As Figures 1 to 5As shown in the figure, this embodiment provides a live working line clamp, which includes a main seat body 1. The main seat body 1 includes a lead clamp part 10. A wire clamp block 2 and a middle clamp block 3 are slidably arranged on the main seat body 1. The middle clamp block 3 is located between the wire clamp block 2 and the lead clamp part 10. A wire groove 40 is formed between the middle clamp block 3 and the wire clamp block 2, and a first lead groove 41 is formed between the middle clamp block 3 and the lead clamp part 10. Fixed rod parts 11 are arranged at both ends of the lead clamp part 10. A lead clamp block 5 is sleeved on the fixed rod parts 11. The lead clamp block 5 is provided with a movable hole 50 and is hung on the fixed rod part 11 through the movable hole 50. A second lead groove 42 is formed between one inner wall of the movable hole 50 and the fixed rod part 11. A first threaded hole 51 penetrating the lead clamp block 5 and a screw rod 52 threadedly connected to the first threaded hole 51 are arranged on the other side thereof. A positioning hole 6 is arranged on one side of the fixed rod part 11 facing the first threaded hole 51 along the axial direction of the screw rod 52. When not in use, only the end of the screw rod 52 needs to be screwed into the positioning hole 6 to position the screw rod 52 through the positioning hole 6, prevent the lead clamping block 5 from rotating, avoid the need to readjust the position of the lead clamping block 5 every time an operation is performed, reduce the operation time, improve the operation efficiency, and at the same time, avoid the generation of noise due to the random shaking of the lead clamping 5 block during transportation or carrying.

[0031] Among them, the positioning hole 6 is a circular hole adapted to the screw rod 52, or the positioning hole 6 is an oblong hole adapted to the screw rod 52. In this embodiment, the former is preferably selected.

[0032] Furthermore, a spring 7 is sleeved on the part of the screw rod 52 located in the movable hole 50. Both ends of the spring 7 respectively abut against the fixed rod part 11 and the lead clamp block 5. The spring 7 is a compression spring. Under the action of the spring 7, the second lead groove 42 formed between one inner wall of the movable hole 50 and the fixed rod part 11 can pre-clamp the lead during wiring, and then the lead is completely fixed by rotating the screw rod 52, reducing the wiring difficulty.

[0033] Secondly, a first annular groove 70 is coaxially arranged on the fixed rod part 11 outside the positioning hole 6, and / or a second annular groove is coaxially arranged on the lead clamp block 5 outside the first threaded hole 51. Both the first annular groove 70 and the second annular groove can be inserted into the end part of the spring 7, which is beneficial to positioning the spring 7 and at the same time reduces the assembly difficulty of the product.

[0034] Further, a sliding groove 12 is provided on the main seat body 1. The wire clamping block 2 includes a sliding seat portion 20 slidably disposed in the sliding groove 12. A second threaded hole and a limiting rod 21 threadedly connected to the second threaded hole are provided on the end surface of the sliding seat portion 20 facing the sliding groove 12. A limiting sliding groove 121 penetrating the main seat body 1 is provided on the end surface of the sliding groove 12 facing the second threaded hole. The limiting rod 21 is slidably disposed in the limiting sliding groove 121. Through this setting, the sliding range of the wire clamping block 2 in the sliding groove 12 can be limited, and the wire clamping block 2 can be prevented from detaching from the sliding groove 12.

[0035] It further includes an operating member 8. A circular ring is provided on the operating member 8. A through third threaded hole 23 is provided on the sliding seat portion 20 along the sliding direction. A through hole 13 is provided at one end of the main seat body 1 close to the lead clamping portion 10. The through hole 13 is coaxially arranged with the third threaded hole 23. One end of the operating member 8 passes through the through hole 13 and is threadedly connected to the third threaded hole 23. A limiting ring 80 is provided on the portion of the operating member 8 outside the through hole 13. A convex block portion 14 is provided on the main seat body 1 on at least one side of the through hole 13. A fourth threaded hole 140 and a limiting member 141 threadedly connected to the fourth threaded hole 140 are provided on the convex block portion 14 along the radial direction of the limiting ring 80. The limiting member 141 is used to limit the axial movement of the operating member 8. In this way, by rotating the operating member 8, the wire clamping block 2 can clamp the wire in the sliding groove 12.

[0036] Wherein, a V-shaped clamping surface is formed on one side of the middle clamping block 3 corresponding to the first lead groove 41, and an arc-shaped clamping surface is formed on one side of the lead clamping portion 10 corresponding to the first lead groove 41; V-shaped clamping surfaces are formed on one side of the middle clamping block 3 and the wire clamping block 2 corresponding to the wire groove 40; Arc-shaped clamping surfaces are formed on one side of the middle clamping block 3 and the fixed rod portion 11 corresponding to the second lead groove 42. The V-shaped design helps to naturally guide the cable to the central position, forming a self-locking effect, reducing the displacement risk of the cable during the clamping process, ensuring fixation during live working, improving safety, and the arc-shaped clamping surface can evenly distribute the pressure acting on the cable, reducing cable damage or deformation caused by concentrated pressure. In addition, the combination of the V-shaped clamping surface and the arc-shaped clamping surface enables the wire clamp to adapt to various different specifications and sizes of cables.

[0037] During use, the leads are sequentially passed through the second lead groove 42 and the first lead groove 41, the screw 52 is tightened with a wrench so that the leads are fixed on the wire clamp. Then, the head of the gun-type operating rod is hooked onto the circular ring on the operating member 8, and the gun-type operating rod is locked. Then, the wire clamp and the leads are hung towards the wire direction with the gun-type operating rod, ensuring that the wire enters the wire groove 40 of the wire clamp. Finally, the gun-type operating rod is rotated clockwise to lock the wire.
