Then, a rack 19 is provided on the bottom walls of the two insertion columns 7. Then, a gear 13 is meshed and connected below the two racks 19. At the same time, a rotating shaft 14 is fixedly penetrated through the central axis positions of the two gears 13. And both ends of the two rotating shafts 14 are rotationally connected to the bottom wall of the support base 1 through two limit seats 12 in a limited manner. Then, one end of the two rotating shafts 14 is rotationally penetrated through the surface of the limit seat 12 and connected with a worm gear 15. And the two worm gears 15 are meshed and connected with a worm 16 below. At the same time, a rotating rod 17 is jointly penetrated through the central axis positions of the two worms 16. And the rotating rod 17 is rotationally connected to the bottom wall of the support base 1 through a limit block in a limited manner. Finally, an adjusting knob 18 is fixedly sleeved and connected to the outer side wall at the middle position of the rotating rod 17. Through the setting of the adjusting knob 18, the rotating rod 17 can be rotationally adjusted;

[0022] When adjusting and using, first adjust and rotate the rotating rod 17 through the adjusting knob 18, and then drive the two worms 16 to rotate through the rotating rod 17. The lines on the worm 16 that mesh with the worm wheel 15 are opposite, so that when the two worms 16 rotate synchronously, the two worm wheels 15 will drive the two rotating shafts 14 to rotate in the opposite direction, and the rotating shafts 14 that rotate in the opposite direction drive the two gears 13 to rotate in the opposite direction, and then the two gears 13 are meshed and connected with the two racks 19, so that the two plug posts 7 are moved away from each other until the two plug posts 7 are adjusted to the appropriate positions. The setting of this structure can quickly and stably adjust and fix the two plug posts 7, thereby improving the practicality of the device;

[0023] As a further implementation of this embodiment, Figures 1-4 As shown, a support plate 8 is provided at one end of the two plug posts 7 which are away from each other, and then a lifting ring 9 is provided on the support plate 8. The lifting ring 9 is U-shaped, and both ends can be threadedly screwed with connection nuts. At the same time, a pillar 2 is provided on the top wall of the support seat 1, and a lower hoop ring 3 is provided on the top of the pillar 2, and then an upper hoop ring 4 is provided above the lower hoop ring 3, and then a mounting plate 5 is provided on the top of the upper hoop ring 4, and two anchor bolts 6 are symmetrically threaded on the surface of the mounting plate 5, and rubber anti-skid pads 10 are provided on the inner side walls of the lower hoop ring 3 and the upper hoop ring 4, and a fixing plate 11 is fixedly connected at both ends of the lower hoop ring 3 and the upper hoop ring 4, and the two fixing plates 11 abutting against each other are connected by screw limiters;

[0024] When the device needs to be fixedly installed on the roof, the device can be fixed in position by the matching arrangement of the mounting plate 5 and the two anchor bolts 6. At the same time, the lower hoop ring 3 and the upper hoop ring 4 can be clamped and installed on the tubular component, and the lower hoop ring 3 and the upper hoop ring 4 can be fixed by installing screws on the fixing plate 11, thereby supporting and fixing the support seat 1 and the whole. By setting the rubber anti-skid pad 10, it is not easy to rotate, and the clamping stability is improved. The power line passes through the lifting ring 9, and the lifting ring 9 is installed on the support plate 8. The lifting ring 9 is fixed by a nut, thereby fixing the power line;

[0025] Specific working principle:

[0026] When the device is in use, the support seat 1 is first installed and fixed, and then the power line is passed through the lifting ring 9, and the lifting ring 9 is installed on the support plate 8. The lifting ring 9 is fixed by a nut to fix the power line, and then the rotating rod 17 is adjusted by the adjusting button 18, and then the two worms 16 are driven to rotate by the rotating rod 17. The patterns on the worm 16 that are meshed with the worm wheel 15 are opposite, so that when the two worms 16 rotate synchronously, the two worm wheels 15 will drive the two shafts 14 to rotate in opposite directions, and the two gears 13 are driven to rotate in opposite directions through the rotating shafts 14 rotating in opposite directions, and then the two gears 13 are meshed with the two racks 19 to make the two plug posts 7 move away from each other until the two plug posts 7 are adjusted to a suitable position, which is convenient for the installation of power lines with different spacings.
