[0023] Reference Figure 1-Figure 4 , an adjustable composite insulating crossarm, including an insulating frame 2, a slide groove 1 is opened at the top of the insulating frame 2, a plurality of sliders 5 are slidably connected in the slide groove 1, a fixed block 4 is fixed to the top of the slider 5 by a bolt, a first card groove 15 is opened inside the fixed block 4, an insulating sleeve 3 is installed in the first card groove 15, a first fixing component is provided between the insulating sleeve 3 and the fixed block 4, the first fixing component fixes the insulating sleeve 3 and the fixed block 4, thereby stabilizing the position of the insulating sleeve 3, an avoidance groove 6 is opened inside the slider 5, one end of the slide groove 1 is rotatably connected to a connecting rod 7, and the connecting rod 7 is located in the avoidance groove 6, and a plurality of protrusions 8 are installed on the outside of the connecting rod 7 to avoid A second slot 17 is provided on one side of the positioning slot 6, and the protrusion 8 is engaged with the second slot 17. A detachable second fixing component is provided between the other end of the connecting rod 7 and the insulating frame 2. The staff rotates the connecting rod 7 to rotate the protrusion 8 and separate it from the second slot 17. At this time, the slider 5 loses its restriction, and the staff pushes the slider 5 to move it along the slide 1 to the required position, and then reverses the connecting rod 7 to re-engage the protrusion 8 in the second slot 17, and fixes the position of the connecting rod 7 through the fixing component, so that the position of the insulating sleeve 3 on the fixing block 4 is adjusted and fixed, which is convenient for the staff to move according to the change in the position of the wire to be supported.

[0024] In the present invention, it should be noted that the first fixing component includes a threaded groove 16, which is provided on the inner wall of one side of the fixing block 4, and a slot 18 is provided inside the bottom end of the insulating sleeve 3. A threaded rod 14 is inserted into the slot 18, and the threaded rod 14 is threadedly connected to the threaded groove 16. When the insulating sleeve 3 needs to be disassembled, the threaded rod 14 is rotated to move along the slot 18 and out of the threaded groove 16. At this time, the insulating sleeve 3 loses its restriction, and the staff can directly move the insulating sleeve 3 upward from the fixing block 4. The second fixing component includes a notch 13, which is provided inside the part of the connecting rod 7 extending out of the insulating frame 2, and a rotating rod is slidably connected in the notch 13. The movable block 11 and the insulating frame 2 have a groove 10 on one side, and the rotating block 11 is located in the groove 10. A spring 12 is welded on one side of the groove 13, and the spring 12 is fixed to the rotating block 11. The staff pulls out the rotating block 11 along the groove 13 until it moves out of the groove 10. At this time, the spring 12 contracts, and then the rotating block 11 is rotated to drive the connecting rod 7 to rotate. The inside of the slide 1 is fixed with a guide rod 9 by bolts, and the guide rod 9 is slidably connected to the slider 5. The guide rod 9 can guide the slider 5 so that it can move stably. One end of the threaded rod 14 passes through the fixed block 4 and is welded with a knob, which is convenient for the staff to rotate the threaded rod 14 with ease.

[0025] Working principle: When the position of the insulating sleeve 3 needs to be adjusted, the staff first moves the rotating block 11 along the slot 13 until it moves out of the groove 10. At this time, the spring 12 contracts, and then the rotating block 11 is rotated to drive the connecting rod 7 to rotate, so that the protrusion 8 rotates and separates from the second slot 17. At this time, the slider 5 loses its restriction, and the staff pushes the slider 5 to move it along the slide 1 to the required position, and then reverses the rotating block 11 to make the protrusion 8 re-engage in the second slot 17, release the rotating block 11, and the spring 12 rebounds and extends, so that the rotating block 11 is re-engaged in the groove 10, thereby adjusting and fixing the position of the insulating sleeve 3 on the fixed block 4, so that the staff can move the insulating sleeve 3 according to the position change of the wire that needs to be supported.
