[0002] Power maintenance refers to the regular or temporary inspection, maintenance, and repair of power equipment to ensure the normal and safe operation of the power system. Power maintenance typically includes the following aspects: equipment maintenance, line maintenance, grounding maintenance, and protection maintenance. In the power system, various equipment and lines will experience long-term operation or face sudden failures, which can lead to problems such as equipment aging, loose lines, or short circuits. Through regular maintenance work, these problems can be identified and resolved, ensuring the reliable power supply of the power system.

[0003] Wire clamps are important tools in the construction and maintenance of overhead power lines. They are mainly used to adjust sag, tighten conductors and ground wires. Depending on the type of conductor and the operating conditions, wire clamps are divided into various types such as insulated conductor, steel strand, single and double jack, and frog clamp. They are mainly made of aluminum alloy, manufactured through forging and heat treatment processes, and the surface is treated with powder coating.

[0004] When a cable clamp grips a power cable, it relies on its self-locking mechanism to hold and lock the cable. However, in damp or greasy areas, insufficient friction at the engagement point can easily occur, leading to insufficient gripping force and the cable clamp falling off. To prevent the cable clamp from falling off, an anti-fall-off cable clamp for power maintenance is provided. Summary of the Invention

A connecting block 802 is fixedly connected to the outer wall of the movable column 801. A first spring 803 is connected between the connecting block 802 and the mounting plate 1. A vertical rod 804 is fixedly connected to the bottom end of the connecting block 802. The outer wall of the vertical rod 804 is provided with locking teeth. The positioning mechanism 8 also includes a rotating column 805, which is rotatably connected to one end of the mounting plate 1. A first bevel gear 806 is fixedly connected to the outer wall of the rotating column 805. A second bevel gear 807 is rotatably connected to the interior of the mounting plate 1, located on the outer wall of the first bevel gear 806. A threaded rod 808 is fixedly connected to the top end of the second bevel gear 807. A displacement block 809 is slidably connected to the outer wall of the grooved rod 808. The displacement block 809 is slidably connected to the inside of the mounting plate 1. A displacement seat 810 is fixedly connected to the outer wall of the displacement block 809. A displacement groove 811 is provided inside the mounting plate 1 for the displacement seat 810 to slide. A vertical groove 812 is provided on the outer wall of the displacement seat 810 for the vertical rod 804 to slide. A cylindrical groove 813 is provided inside the displacement seat 810 on one side of the vertical groove 812. A steel ball 815 is slidably connected to the inner wall of the cylindrical groove 813. A second spring 814 is connected between the steel ball 815 and the cylindrical groove 813. A pusher frame 816 is slidably connected inside the displacement seat 810 below the steel ball 815. The pusher frame 816 extends to the bottom of the displacement seat 810.

[0024] In this embodiment: when the slide rod 10 slides in the slide groove 12, the slide rod 10 contacts the movable column 801, pushing the movable column 801 to move. When the slide rod 10 separates from the movable column 801, the connecting block 802 is reset by the elastic force of the first spring 803. The displacement of the connecting block 802 drives the movable column 801 to reset. When the movable column 801 moves, the displacement of the movable column 801 drives the vertical rod 804 to move through the connecting block 802. The vertical rod 804 slides in the vertical groove 812. When the upper clamping plate 4 and the lower clamping plate 2 clamp the cable, the slide rod 10 is in the slide groove 12, and the movable columns 801 at the front and rear of the slide rod 10 are in contact with the slide rod 10. After completion, the rotating column 805 is rotated, which drives the first bevel gear 806 to rotate. The first bevel gear 806 drives the second bevel gear 807 to rotate. The second bevel gear 807 drives the threaded rod 808 to rotate. The threaded rod 808 drives the displacement block 809 to move. The displacement block 809 drives the displacement seat 810 to move. The displacement seat 810 slides in the displacement groove 811. At this time, the vertical rod 804... Sliding within the vertical groove 812, when the displacement seat 810 moves to the top of the displacement groove 811, the push frame 816 separates from the steel ball 815. The steel ball 815 is displaced by the elastic force of the second spring 814 and contacts the locking teeth on the vertical rod 804, thus preventing the vertical rod 804 from moving downward relative to the displacement seat 810, thereby positioning the vertical rod 804 and fixing the position of the movable column 801. The movable column 801 fixes the slide rod 10 within the slide groove 12, preventing the upper clamping plate 4 and the lower clamping plate 2 from moving away from each other, thereby preventing the upper clamping plate 4 and the lower clamping plate 2 from loosening their clamping of the cable. When the cable is loosened, rotating the rotating column 805 causes the displacement seat 810 to move downward along the displacement groove 811. At this time, the vertical rod 804 moves upward relative to the displacement seat 810. Simultaneously, the pushing frame 816 contacts the bottom end of the displacement groove 811. The pushing frame 816 moves relative to the displacement seat 810, pushing the steel ball 815 to move and squeezing the second spring 814, causing the steel ball 815 to separate from the locking teeth on the vertical rod 804, so that the vertical rod 804 can slide up and down in the vertical groove 812.
