The described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-Figure 4 , an adjustable cross arm, including two fixing frames 1, the outer walls of both ends of the fixing frames 1 are fixed with mounting rods 5 by bolts, the interior of the mounting rods 5 is provided with a winding assembly with adjustable distance, one end of the fixing frame 1 is rotatably connected with a clamping plate 2, the top of the fixing frame 1 located below is fixed with a fixing rod 3 by bolts, the top of the fixing rod 3 is provided with a threaded hole 6, the bottom of the fixing frame 1 located above is fixed with a sliding rod 4 by bolts, and the sliding rod 4 is slidably connected with the fixing rod 3, an avoidance groove 8 is provided inside the sliding rod 4, a screw 7 is provided inside the avoidance groove 8, and the screw 7 passes through the avoidance groove 8 and is threadedly connected with the threaded hole 6, a card slot 18 is provided inside one end of the fixing frame 1, and one end of the clamping plate 2 is located in the card slot 18, one end of the fixing frame 1 is provided with a limiting component for fixing the clamping plate 2, the two clamping plates 2 are rotated to open, the device is put on the outside of the electric pole through the fixing frame 1, and then the clamping plate 2 at the top is fixed to the fixing frame 1 through the limiting component, and the fixing frame 1 at the bottom is pulled downward to cause sliding extension between the sliding rod 4 and the fixing rod 3, and then the screw 7 is aligned with the threaded hole 6, so that it passes through the avoidance groove 8 and is rotated to be inserted into the threaded hole 6, thereby lengthening the length of the sliding rod 4 and the fixing rod 3 after the position is changed, and then the distance between the two clamping plates 2 is adjusted and fixed, and finally the clamping plate 2 at the bottom and the fixing frame 1 are fixed by the limiting component.

[0023] In the present invention, it should be noted that the winding assembly includes a slide groove 11, which is opened inside the mounting rod 5, and a connecting rod 15 is slidably connected inside the slide groove 11. The top of the connecting rod 15 passes through the slide groove 11 and is bonded with a porcelain bottle 10. The bottom end of the connecting rod 15 is rotatably connected with a screw rod 13, and the outer side of the screw rod 13 is threadedly connected with a slide plate 14. When it is necessary to adjust the distance between two porcelain bottles 10 on the same mounting rod 5, the porcelain bottles 10 are pushed to move the two along the slide groove 11 to the required distance, and then the screw rod 13 is rotated to make the slide plate 14 move upward along the screw rod 13 and come into close contact with the rubber strip 12, thereby adjusting and fixing the distance between the two porcelain bottles 10. Two rubber strips 12 are bonded to the bottom outer wall of the mounting rod 5, and the slide plate 14 is in contact with the rubber strip 12. The rubber strip 12 can increase the friction between the slide plate 14 and the bottom of the mounting rod 5. The limiting component includes a mounting column 16, which is fixed to one end of the fixing frame 1 by bolts. The outer side of the mounting column 16 is rotatably connected with a baffle 19, and the baffle 19 is in contact with the clamping plate 2. A torsion spring 17 is sleeved on the outer side of the mounting column 16, and the two ends of the torsion spring 17 are respectively fixed to the mounting column 16 and the baffle 19. Release the baffle 19 at the top, and the torsion spring 17 rebounds and resets, so that the baffle 19 rotates and contacts the clamping plate 2 again, thereby making the baffle 19 limit the position of the clamping plate 2. A hexagonal block 9 is welded at the bottom end of the screw rod 13, which is convenient for the staff to use tools to rotate the screw rod 13. The mounting rods 5 are respectively located on both sides of the fixing frame 1, and the multiple mounting rods 5 are symmetrically distributed.

[0024] Working principle: When the device needs to be installed, first move the baffle 19 to separate it from the clamping plate 2, deform the torsion spring 17, then rotate both clamping plates 2 to open, put the device through the fixing frame 1 to the outside of the pole, then loosen the baffle 19 at the top, the torsion spring 17 rebounds and resets, so that the baffle 19 at the top rotates and contacts the clamping plate 2 again, then pull down the fixing frame 1 at the bottom, so that the sliding rod 4 and the fixing rod 3 slide and extend, then align the screw 7 with the threaded hole 6, pass it through the avoidance groove 8 and rotate it into the threaded hole 6, so as to change the position. After the slide bar 4 and the fixed bar 3 are placed, the lengths become longer, thereby adjusting and fixing the distance between the two clamps 2. Then, the baffle 19 at the bottom is released, and the torsion spring 17 rebounds and resets, thereby rotating the baffle 19 at the bottom and contacting the clamp 2 again. When it is necessary to adjust the distance between the two porcelain bottles 10 on the same mounting rod 5, push the porcelain bottles 10 so that the two move to the required distance along the slide groove 11. Then, rotate the screw rod 13 so that the slide plate 14 moves upward along the screw rod 13 and contacts the rubber strip 12 closely, thereby adjusting and fixing the distance between the two porcelain bottles 10.

[0025] Finally, it should be noted that: for those skilled in the art, they can still modify the technical solutions recorded in the above embodiments, or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this utility model shall be included in the protection scope of this utility model.
